My attempt at installing the R&P gears in my rev-cut 44 front axle failed miserably.
With the pinion in, yoke torqued down, and carrier pressed in, there was still slop in the pinion gear (up/dn, wiggle) and the ring and pinion were not even touching each other.

The carrier is from a Jeep TJ std-cut 44 rear axle, it's a Trac-Loc. The gears are definitely rev cut 4.56s (D44-456R on box).

Is there a difference between std-cut and rev-cut carriers?? I looked up ARB lockers as a reference and only found 1 listed, not one for std and one for rev.
Do they make rev-cut and std-cut bearing/overhaul kits, and is it possible I got a std-cut bearing/overhaul kit?? I couldn't find the master kit box just now, I'll look for it in the morning.

Here's a pic of what's up with the gears:

The only difference between RC and Standard Cut diffs are the gears, not the carriers. You need a normal 4.10 and numerically higher carrier to run your 4.56s in a RC housing. I think the Jeep TJ rear D44 carrier is a normal 3.92 and numerically lower carrier, but they use a thick 4.10 ring gear to space the gear closer to the pinion. There are no differences in the installation kits either.

So, just get a different carrier and you are good to go.

Thanks Eric. Bummer, was hoping someone would say yeah it's the install kit! :(

Eric,
Does that a Ford r/c Dana 44 has a different gear spilt than a std 44. I thought that the lower gears were 3.73 4.10 4.56. etc.. and the taller gear carrier was 3.50. below?

I spoke with Mike at Rearend Specialties this morning, he told me the same thing Eric posted; the split is at 3.92 not 3.73.

well, then you getting a detroit? I will be heading over shortly... need some steel first.

Later

fuck no. Bad timing, with getting the tires. Guess I'll stick a truetrac (or the like) in there for this season.

Ok I ran into a similar situtation on a R/C 60 here a couple of weeks ago....There are different types of carriers High Speed and Low speed I can't remember exactly what the difference is but the gear set I had was for a low speed carrier and the locker I had was a high speed carrier style.....Could this be the same thing? And what exactly is the difference between them?

High speed and low speed? Never heard that term before. I assume you mean what makes the difference betwwen the numercally higher number carriers and the lower carriers right. The difference is in the distance between the pinion and the mounting surface on the carrier for the ring gear. As you go numerically higher in the gears the pinion gets small requireing a thicker ring gear to make them match correctly. By chaning the carrier it allows you go with lower gears and have a skinnier ring gear whick in turn is lighter lessdrag etc.

I hope that makes sence.

It is a waste of gear steel to make thick ring gears so they move the ring gear mounting surface on the carrier closer to the pinion for the numerically higher gear ratios.

I have never heard the terms high speed and low speed carriers, but am guessing they are a good way of determining which carrier you need for which gear set. A high speed carrier is probably for numerically lower gears (D60 4.10 and lower) and a low speed carrier is for numerically higher gears (D60 4.56 and higher)?

Now RC D60s are different. I think they only use one carrier, the high speed carrier. When you want to run 5.13s on a RC D60, you use the same carrier for the 4.10 and lower gears. For some reason the gear makers who make the RC D60 gears just make a thicker gear to take up the difference between the pinion and ring gear as the numbers get higher.

Why can't they do this for all D60s? It would make locker selection so much easier if you ever had palns on getting a RC D60. Can you imagine buying an ARB or Detroit and then having to buy another one if you wanted to switch over to a RC housing? :rolleyes:
