The 14 Bolt Bible
By BillaVista


I Intend to use this article to gather all the info and pics I can find on the venerable GM "corporate" 14 Bolt (14b) full-floating rear axle, also referred to as the 10.5" (after the size of the ring gear in inches.) There are "other" 14b axles out there - a 9.5" ring gear semi-float for one, and even a 11.5" ring gear full-float version. This article is NOT about them.

It is almost certainly destined to be a perpetual "work in progress" as I gather more and more info.

I compiled them all into a single 14 bolt manual in pdf format.


Identification, data, and specs

Land vehicle Vehicle Tractor Car Auto part


The 14bolt is found in a huge number of GM 4x4 pickup trucks and vans, 3/4 and 1 ton, from the 70s right through until at least 2000. You can find it in:
  • 73-96 C20, C2573-00 C30, C3573-00 G30, G3573-00 K20, K2573-00 K30, K3584-88 CUCV
  • 88-91.5 V30

As well as a whole lot more cab and chasis trucks, delivery vans, etc.

It is most easily distinguished by its huge, uniquely shaped diff cover that is, of course, held on with 14 bolts.

It is also fairly easily distinguished from other 1 ton full-float rear axles by the removable pinion support, that can be clearly seen just behind the pinion yoke in the above picture.

Being a full float (FF) axle, it of course has full floating wheel hubs and axle shafts. I simply love full-float axles, and would never go back to running anything but a FF axle, for some very good reasons:
  • The axle shaft does not support the weight of the vehicle, but merely transmits torqueBecause of the above - FF axle shafts are not subject to bending loads like semi float (SF) axles are and can therefore be made of harder materials making them capable of carrying greater torque loadsIf you should ever break a rear FF axle shaft, you will not loose the wheel too.If you need to change a FF rear axle, it is extremely easy and simple to do.The hubs run big, strong, common, reasonably cheap wheel bearings, races, and seals (14b Dana 60 and 70 bearings, front and rear, are all the same)
  • The wheel bearings are not pressed onto anything, if need be they can be removed and replaced with nothing more than a screwdriver and big hammer.

Before we delve deeper into the 14bolt, let's just talk about why this is such an awesome axle. It has a number of distinct features / advantages:
  • Gear strength - 10.5" ring gear, 1.750" 30 spline pinion, huge 2 piece carrier made of 8620
  • Heat treated alloy steel, extra pinion bearing support
  • Shaft strength - 1.5' 30 spline full floating shafts
  • Housing strength - massive cast iron center section, 3.25: x 0.5" tubes
  • Comes in two widths - 63" and 67" wms-wms, easily converted from one to the other (shafts are common)
  • Removable pinion support, unbolts from the rest of housing, makes for easier gear setup
  • Diff housing has built-in threaded carrier pre-load adjusters, makes for easier gear setup
  • Because the carrier is so large and strong, a "full" detroit locker fits in the stock housing, and is therefore easy to install without gear setup changes, and is much cheaper than other 1 ton FF lockers
  • Pinion yokes commonly available for 1350 series u-jointsFairly commonly came stock with 4.10 and 4.56 gears and Detroit Lockers
  • Cheap and easy to find, buy, and build
  • Easy to convert to disc brakes
  • Easy to "shave" for 2" inch gain in clearance
  • Pinion length shorter than other 1 ton ff rear axles (D60, D70), for improved driveshaft length and angles
  • Large ID spindles
  • Common spindle nut threads with Dana60 front axle, meaning only one style of spindle nut and socket need be used / carried

Of course, there are drawbacks too:
  • Lack of traction aiding differentials - especially spoolsLack of available gearing - only down to 5.13
  • Lack of aftermarket alloy axle shafts
  • Carrier break. Most 1 ton ff also have a carrier break though, so it's relative
  • Uses a crush sleeve to set pinion preload heavyLow clearance in stock form
  • Heavy in stock trim

Overall, I think they are a superb choice for a heavy duty off-road machine. I'll let H8Monday, from the PBB, sum it up, as he does so well. H8 is a rock crawling competitor, devout throttle crazy maniac, who runs a 14b behind a very healthy 5.0. He says:

"One of the best things about the 14 bolt, other than they are dirt cheap and nearly indestructible, is the cost of building them. It is very common to find them with 4.56 gears, and often axle shops and junk yards will have used factory sets. They are very easy to set up, because they have an adjustable backlash. Spare axle shafts are nearly free, and the shafts are the same for the C&C or standard version. Not that spares are usually necessary with a 1.69" axle shaft diameter, (splines are 30). But, the best thing is, because the stock carrier is a monstrous hunk of an assembly, you do not change the carrier with a Detroit,(its basically a massive lunch box locker). So detroit only cost about $325(and that's if you don't shop around). My disk brake conversion didn't cost over $150 ($40 each for rotors, $40 for loaded calipers, plus about $20 for brake lines. I had about $1000 into my entire 14 build up, including cost of the axle, gears, locker, disc brakes, and new lug nuts. Not bad for a full floater, rear axle with discs, 4.56 gears and a detroit."
Let's have a closer look at the beast.

Watch out for this when you go to remove the wheel hub outer bearing and race. The bearing does not simply fall out of the end of the hub on most FF axles - its OD keeps it captive. Instead, a snap ring in the hub, accessible from the back of the hub (yellow arrows) needs to be removed so the wheel bearing can come out the back.

Blue arrows show corrosion, indicating requirement for replacement bearings and races.

These pics are of the carrier removed. Mine is fully welded up making it a huge spool. I have read about some folks just welding the spider / side gears by filing in the valley's between the teeth and then reinstalling them. I personally have never understood this. It's not as if you need to save the carrier, since they are cheap and extremely plentiful. Also, I would think that in this manner, those welds would see quite a bit of shock loading. It's also a real bugger to reassemble the carrier and gears after you have just welded up the teeth and are trying to save the carrier.

It's very simple setup that consists of one hub nut, one key, and one clip ring. The nut accepts the regular 6 prong 14 bolt socket and has 6 square grooves around its inner diameter. These grooves are what you line up with the spindle groove to make the key way.

I just tighten down to the correct preload and then tighten until the next groove in the nut lines up with the spindle groove.

Then you simply slide the key in the key way and put on the clip ring. The clip ring has a curved end that fits in the spindle groove to securely block the key from backing out. The clip is very thin and flimsy which makes it easy to remove with just a screwdriver and allows it to fit snugly around the spindle in the threads.

The different types of 14 bolt

There are many different 14 bolt axles available, with an almost dizzying array of possible widths, tube OD's, hub types, brakes etc. Fortunately, all are pretty similar, a huge number of parts interchange, and through the power of the internet and Pirate4x4.com we are beginning to catalogue all the available data here.

CAUTION - With this axle, as indeed with all things "axle" like - there are no hard and fast laws - for every "fact" I shall present, I know there's at least one person out there, maybe many more, who claim they own or know of exceptions. This is very likely true and due to the way in which oem vehicle construction occurs, can not be avoided or completely resolved. What follows is what i believe to be true, or the most correct, information based on the research I have done and the letters I have received from what I judge to be the most reputable sources. Use the data with caution - "your mielage may vary" as they say.14 Bolts can be broken down into 4 broad groups. There is also at least one year break that bring minor changes, but this is in fact far less significant than the "type" of 14 bolt axle in question.

Once again - this article is concerned only with GM 14 Bolt full-float rear drive axles. With that said, the following table attempts to capture the data.

Type [td]Width WMS-WMSTube OD / ThicknessApplicationsHubs *Shafts * *
SRW (single rear wheel truck)67.5"3-3/8" / 0.5"Type AType 1
DRW (dual rear wheel truck)72"3.5" / 0.5"Type BType 2
C&C (cab and chasis truck)63.5"3.5" / 0.5"Type BType 1
Van70"G30 and G35Type AType 3

Notes:
  • The SRW and C&C axles use the same housings and shafts, with the difference in width being in the hubs. The housings are actuallly identical except for the location of the backing plate flange. Drums & hubs are different, but backing plates, shoes, and wheel cylinders are the same)
    * The SRW and Van axles use the same hubs, the C&C and DRW axles use the same hubs; Though different, the SRW/Van hubs and the C&C/DRW hubs can be interchanged causing a change to the axles WMS (see pics below) SRW and C&C axle shafts are the same
    ** Van, DRW, and SRW/C&C axle shafts are all different lengths as follows (long/right side / short/left side):
    • Type 1 - SRW/C&C - 37-5/8" / 31-5/8"Type 2 - DRW - ??
    • Type 3 - Van - 39-3/8" / 33-3/8"

    C&C and dually brakes are the same. In all cases one side axleshaft is shorter than the other; pinions are centered. 1350 appears to be the only available stock pinion yoke.1-tons feature 40.5" perch spacing - whether C&C or pickup, whether SRW or DRW. 3/4-ton is 42.5" spacing.
    (COUNTER) - The perchs on my C&C measure 36"
    Wheel studs went metric for the 88-up C/K trucks, and 96-up vans
  • Front 60 and rear 14b spindles have the same bearing spacing and same bearing journal sizes. Seal journal is different

Different years

The year split is '72-88 and 89+. I shall refer to these as "first design" and "second design". Of course, there may be variations. Differences between these years are noted below. Where the difference is known only to apply to certain "types", I shall indicate this. Otherwsie, it is not known whether the differences noted between the years apply to all types or not.

  • Second design axles have more fins on the center sectionFirst design axles 1984 and earlier use a different pinion straddle bearing than 1985 and later
  • Second design SRW axles in 1-ton pickup trucks and 3/4 ton Suburbans changed to allow for a slide-off drum (drum can be removed without pressing out the wheel studs). The backside of these hubs is not machined flat to accept a rotor, for example. The hub flange is also further inboard to allow for the thickness of the drum.

How to Convert the 14 Bolt to Disc Brakes

Check the full article HERE How to Cure the 14-bolt of it's Achilles Heel weak link!

The Mighty, mighty 14-bolt does have 1 terrible weak link - an Achilles Heel. It's the crappy, lousy design, weak, expensive and hard to find straps for holding the U-joint in the pinion yoke.

Still life Circle


The proper straps are a pain to find. No parts store I have ever tried, from NAPA to Car Quest ever has them.

That leaves only the GM dealership, where the strap (GM p/n: 3920486) will set you back $3 EACH! and the bolts (GM p/n: 458300 or 14018700) another $2 EACH.

Metal Hardware accessory


As for all the local and big chain parts stores - they will all gladly sell you a "strap kit" for a "1-ton GM rear axle" or "GM 10.5" rear end" or a "14 bolt full floater" or a "1980 Chevy K30 1 ton 4x4 " or whatever else you have to say to them to get one - but, in my experience (NAPA, Car Quest, Canadian Tire, and a couple of local independents) they are all WRONG, and won't fit at all.

The top strap is the one the parts stores will sell you, the bottom the GM part.

Auto part


In any case - the stock straps are weak and badly designed - very soon they end up looking like this.

Metal

Complete junk!!

Fortunately - there is a solution - and a very cool one at that - read all about it - the High Angle Driveline 1410 Pinion Yoke kit


Shaving the 14 Bolt

The only real disadvantage to the 14b is the huge size of the differential, and subsequent scarcity of ground clearance. I must admit, in stock form, they do tend to hang a little low and get hung up on stuff. Most users will "shave" them. This can range from simply smoothing out the bottom with a hand grinder, to cutting a big chunk out of the bottom of the diff housing and machining down the diameter of the ring gear.

The following pics illustrate the nicest case of the later, more extreme, shaving job that I have come across. It is the work of PBB member 1TONTJ, Phil Jensen, from Ottawa, Canada:

The piece cut from the diff housing. Phil used an abrasive wheel/blade in a circular saw to start, and finished with a reciprocating saw. Starett blades are reportedly good for this.

Auto part Automotive wheel system Tool accessory Gear Machine tool

After the cut of the housing, this is the carrier back in place, before it was machined down. It was then removed and approx 1/4" machined from the OD of the ring gear. This did not effect the performance or durability of the gear set at all.

Just over 2" of clearance was gained. That's the same (at the diff) as going from 35" to 39" tires!!

Originally, Phil made a quick cover by altering a stock cover. It didn't last well enough for his liking, so in the end he constructed a complete custom cover from 3/8" plate steel, which has reportedly held up very well. Unfortunately, I have no pictures of the later cover, but here are some of the original.

From the research I have done (I have no personal practical experience) the methods that have been used successfully for trimming the OD of a ring gear for a radical shave job are:
  • Abrasive grinderDiamond-tip on latheCeramic inserts on lathe
  • Wire EDM
I believe the preferred method is the wire EDM. Here's what engineersedge.com has to say about EDM:

EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries. EDM works by eroding material in the path of electrical discharges that form an arc between an electrode tool and the work piece. EDM manufacturing is quite affordable and a very desirable manufacturing process when low counts or high accuracy is required. Turn around time can be fast and depends on manufacturer back log.
The EDM system consists of a shaped tool, an electrode, and the part. The part is connected to a power supply. To create a potential difference between the work piece and tool, the work piece is immersed in a dielectric (electrically nonconducting) fluid which is circulated to flush away debris.The cutting pattern is usually CNC controlled. Many EDM machine electrodes can rotate about two-three axis allowing for cutting of internal cavities. This makes EDM a highly capable manufacturing process. EDM comes in two basic types: wire and probe (sinker). Wire EDM is used primarily for shapes cut out of a flat sheet or plate. With a wire EDM machine, if a hole needs to be created, an initial hole must first be drilled in the material. Then the wire can be fed through the hole to complete the machining. Sinker (probe) EDMs are generally used for complex geometries where "line of sight" is not thru/straight or very small pieces where conventional milling is not practical or very difficult due to the hardness of the material - such as cast and heat treated tooling. Probe EDM can cut a hole into the part without having a hole pre-drilled for the electrode.


Design Considerations
  • Relax the surface - finish for the part, if feasible. This allows the manufacturer to produce the part with fewer passes, at a higher current level and a higher metal-removal rate.
  • Design the part such that the amount of stock removed by EDM is relatively small. Use traditional machining techniques to remove the bulk of the stock with the finishing operations performed by EDM. This significantly reduces the amount of time and cost for each part.
  • The EDM manufacturer should consider fixturing such that several parts can be stacked and machined simultaneously or a single part can have several EDM operations performed simultaneously.
  • When existing holes are to be enlarged or reshaped by EDM, through holes are preferred to blind holes as they permit easier flow of dielectric fluid past the area being machined

Dimensional Accuracy (+/- 0.0005 inches per inch)

Feature Profile accuracy of .0003 is obtainable with cutting path
Features to feature true position of .002 is reasonable and down to .001 is possible when geometry requires removal and reattachment of wire.

Surface Finish (microinches)
Features created by EDM have an "orange peal" appearance. 32 RMS is achievable, 64 or higher RMS is typical.

Wall Thickness
Min Wall Thickness (inches): 0.01 (over a 5" inch span)

Depth
Significant depths can be obtained with wire EDM, probe EDM does have depth and access limitations dependant on machine capabilities.
Consult with EDM manufacturer for specifics.
