Does a Dana 30 or a 44 use a pinion crush sleeve?

As I am in the process of helping my buddy regear my Dana 30 and 44, I didnt see anywhere in the rebuild kits or in the back of the quadratec catalog a replacement crush sleeve that goes on the pinion. I thought all axles used these and was necessary for the correct preload. Can someone point me in the right direction?

Unless I'm mistaken, they both use shims for pinion preload.

p.s. On today's episode of Extreme 4X4, Ian was installing new gears and a locker in a Dana 44.

I thought the same thing but the master rebuild kit they sell at Morris 4x4 does have a crush sleeve listed as one of the parts for a 1986 and up Dana 44 although I don't see one in the exploded picture of the axle. The Dana 30 parts and picture clearly shows it is shimmed and lists no crush sleeve.

Someone on here had a link to axle identification and factory rebuild instructions. I thought I bookmarked it but can't find it for the life of me.


Morris 4x4 master rebuilt kit description for a Dana 44:
1986 JEEP CJ7 & CJ8 SCRAMBLER MASTER BEARING ,SEAL & HARDWARE KIT W/DANA 44 REAR Axle kit Includes: Pinion,carrier bearings,crush sleeve,oil seals,cover gasket,Axle shaft inner/outer seals and bearings.

Like I said, I don't see it in the picture.



Edit, if you click on #30 it lists it for 70-75 Dana 44 and does not have a crush sleeve listed. #8 is for 1986 and up and does list the crush sleeve. Think it's a typo?

Do either of the axles your taking apart have crush sleeves already in them?

There ya go. If you did not take one out then you don't put one back in. I think the TJ dana 30 uses a crush sleeve but the high pinion D30 and the CJ style long pinion D30 do not. I have not seen a D44 that uses a crush sleeve but I have not worked on one of the newer ones like a Rubicon. So I don't know what the new ones have in them.

The wrangler 30/44 use crush sleeves, the CJs use shims.

The newer XJ and ZJ 30s use crush sleeves too.

So without a crush sleeve, I could remove my yoke to replace the seal without worrying, right? (sorry to derail the thread).

The original, IE older Dana 30 and 44 used shims not a crush sleeve. Many if not all of the new ones do use a crush sleeve. So it depends on year.

The crush sleeve is easier to setup both at the factory and when regearing. Some say the crush sleeve can crush if the pinion takes a strong hit off road, but I find it hard to believe as the hit would have to be pulling the pinion out of the differential for that to happen, a hit that had would likely break other things as well.

So you simply need to get the correct kit for your year. If these are CJ axles then no crush sleeve.

I think all D44s used shims - some D30s used crush sleeves. Got a BoM number? I'm working with Dana lists for the next couple of days or so - gimme application and BoM, and I can confirm.

I don't know why this was dug up from the archives but this is what I know about it.

TJ and ZJ low pinion Dana 30's use a crush sleeve. There are short pinion and long pinion versions of these.
Isuzu Rodeo and Honda Passport Dana 44's use a crush sleeve.

All other Dana 30s and 44s I am aware of use pinion pre-load shims.

Wow Foggy. I didn't even catch the old posts. I even knew that "imtheant" hasn't been here for a while.
Broke my thumb last week. Blaming this senior moment on the medication.
