CTM on a TJ Dana 30 front end ?

[coachgeo]

ok... The TJ and some other rigs use a dana 30 with a dana 44 style and size joint. soooooooo..... then will the CTM fit this too?

[Turtleack]

According to the instructions packed in the CTM box, they cannot be used in stock axles, probably because they are not machined for the circlips instead of the stock clips. They can be used in the aftermarket chrome moly axles though which are made to take the circlips. I am planning to install them in my warn axles as soon as the weather is warm enough to work on them.

[LOS-YJ]

I got CTM's for my 44.... They rock.. They do make it for the 30 I believe cause Jack at CTM runs a 30 with ctms if I remember correctly.. But yeah you cant use stock axles you need to go to chromoly. So you needs new shafts and the joints so its about $900 bucks for everything, I dont know if I would do it on a 30 I'd worry about RP going or other stufff then your looking at some big money stuff, I would just upgrade to a 44 if I was you dude.

[Steve N]

They physically fit but as the above post mentions they take a full circle C clip. Plus, they are made for alloy axles. If you use them in stock axles the stockers will be the very weak link and will break, possibly damaging your U joints.

When I add it up its more like $1,650+
350+ for a pair of inner shafts
300 for a pair of CTMs
900 for the hub conversion kit (includes outer shafts) unless someone started making alloy outer shafts that fit TJ fulltime hubs.

[coachgeo]

well... with an upgrad to a 44.. which I am considering...

I would also have to buy an ARB or OX lock
I have ARB in the Rear..
so that adds a huge cost to the 44...

I'm confused.. why would I have to do a hub conversion?

[CJ-Jeeper]

I don't know myself, but Dan-H seems to have told you why.

[Dan-H]

The CTMs will reportedly eat stock outer shafts. Why spend 150 dollars on a CTM to eat a 100 dollar outer shaft when you can do it with a 25 dollar 297x.

No-one makes an alloy outer to fits the stock TJ hub so thats why you would need a conversion.

Please prove me wrong on this one :) there is one set of alloy outers for stock TJ hubs that I heard were made, but I was told by the person that has them they are not being sold.

The weekest link on the d30 isn't the u-joint, it's the outer shaft. There is a kit that replaces the shafts with the larger 30 spline (d44), but it uses the same size u-joints as the d30 did now becoming the weak link. Someone may know if the CTM shaft will work with this, but I have no clue. It'd be nice - d44 strength with d30 weight and clearance.

CTMs and high strength alloy shafts on a D30, you now have possible ring & pinion strength issues. It all depends where you want your weak link.

[CJ-Jeeper]

I have'nt heard of a 30 spline conversion. Who makes it?

[Dan-H]

warn makes the conversion kit.

5x5.5 kit is 27 spline inner/30 spline outer

5x4.5 kit is 27 spline inner/outer

both use 297 ujoint

Hopefully the hub fuze would go before the R+P.

[CJ-Jeeper]

I guess that's right. They don't list the 30 sp outer on their application chart, but under the description for the conversion kit it does say 30 sp hubs.

[coachgeo]

what about hub blanks?

also... if I had CTM's with stock axils and I broke say I broke an axil inside.. what is the potential damage? Would it be easier to remove and field fix than one that got toasted by a weak stock joint trashing the ears? ...

there is no differance, either way your pulling it apart to fix..... actually breaking the yoke is easier then you dont have to pull the cover and fish out the broken, spline in your carrier...]


and yes, if you dont run warn shafts, youll be destroying stock ones.... i got a few spares i dont need any more :)

and yes it is correct that you can not get alloy stubs unless you do a hub conversion.......lol i got alot of alloy for this year... :) 5 outers, 2 short inners, and 1 long outer.... that might last me a few months...lol

[coachgeo]

ok.... well then a 44 then sounds the best. Im sure im living on borrowed time as it is?

[hybrid]

mabey, you still running 35's? running rough trails then probabaly... with open diff and smaller tires the tire will usally slip before things break. If you can't afford the 44, carry spare shafts and some tools and start $aving. You can always sell the old shafts once u upgrade but sitting in a canyon blocking a trail at 2am waiting for someone to bail u out..... u'll know the F*&kup fairry has visited.

Dan,

I don't remember talking to you about my outers:D . Actually, I can prove you wrong, I had 2 sets made (by Jack) from WARN stubs so I'd have a spare set, I still have the spares and have been running the outers (on Q78's) for about 6 months now with no problems .

HB

[Dan-H]

HB,

I'm pretty sure it wasn't you I was talking to, but I can't really remember now. it was a month or so...

anyway, are there more for sale that fit the stock hubs?

do u mean the stock hub blanks... their are no hubs!

[Daless2]

If anyone is interested the new Superior Evolution D30 shafts(Inner and Outer CrMo Alloy) with Ox U-joint (also CrMo) will be making their public debut in Moab Easter week.



It is my understanding they will be available in limited numbers by the second week of April.


To the best of my knowledge the pricing has not been set yet. It is also my understanding the target will be reasonable (Whatever that means?).


I don't think this will compete with the CTM U-joints, but for those who need stronger then stock axles and u-joints it might fill the bill.


I'm going to be installing them shortly.


For my type of wheeling I think they will work well for me. I'll let you all know what I think of them.

I mean the stock hubs shown in the picture as item 6.

Dan H and HB. Let me clear it up.

Dan saw me make reference to the alloy stock stub replacements without me divulging who made them and who owned them.

I just figured if Jack and HB wanted people to know the specifics, that was their business.

Thank you Frank... This may be good news. We'll no more after EJS I guess. I have never been inside an axil so Im a little dumbfounded here. Will these work with my present Dana 30 ARB and Gears? (456)

Like others here I play hard but not exactly Hardcore so this may fit my bill fine too.

Please keep me posted.

Hi coachgeo,

Yes these Superior Evolution Axles will indeed fit your D30 with ARB.

The install is exactly the same as any other axle install. There should be no additional modification needed.

I do plan to install a set of DTD outer axle tube seals when I do this.

So in my case I will need to pull the ARB carrier so as to be able to clean the caked on mud out of my tubes properly.

But if you are not doing this, you would have no need to touch the carrier at all.

Tell me more about DTD outer axil tube seals... I live in mud country now.. YUKKK. and I should consider some improved sealing tricks if they are available. I dont know if they are? My frront has scared up two sets of carreior bushings in the axils while I lived in NV and CA. From what I have seen on post they look to be contaimanent (water) damage.

Good Morning coachgeo,

I hear you on the mud issue. I avoid it as much as possible. Here in Kentucky we have a lot of streams that must be crossed.

But worse then the streams there are many standing pools of muddy water that must be transversed to get to all the good obstacles.

I have No First Hand Experience with the DTD Dana 30 outer axle seals other then installing a set on a friends Jeep last November. This really is an easy installation.

I do have a set on their way to me as we speak.

Here is a picture of what they look like.

http://www.jeepin.com/features/axleseals/sealsLO.jpg


Each seal replaces the plastic shield that is on the inner axles between the front hubs and the end of the D-30 axle tube.

You slip them on the axle and then slide the axle into the tube, and then push the seal assembly into the tube. It is a nice machined fit.

The seals work when filled with grease via a zerk fitting, sealing both the axle tube and the axle shaft.

Here is a site that details the installation. They really are not difficult to install at all.

http://www.jeepin.com/features/axleseals/

I do know they re available from www.drivetraindirect.com

They may very well be available elsewhere too, I just don't know of any other place.

Hope this helps you out.

Frank
