Hey everybody...

I'm rebuilding an '86 Salsbury rear end, and ordered all my parts from a guy in Oklahoma. Come to find out he doesn't know much about the practical part of the parts he sells...

Anyway, when beginning to reassemble the inner stub axles and housings, I noticed that the crush rings he sent me were straight cylinders rather than ones with a "dimple" for want of a better description, around the perimeter that will obviously deform outwardly when preloading the bearings.

Question is "did I get the wrong crush sleeves"? (I called him and he insists that they are correct.

OR if nobody knows the answer here, does anybody know anybody locally in Austin that knows all about Jag rear ends?

Thanks in advance.

Thanks, Dick..

Aww, heck, it doesn't make any difference where any parts come from. I was asking about Austin because I'm probably OC... hahah.. and am anxious to get all this straightened out and proceed with the rebuild. So bottom line, it doesn't make any difference.

So you are saying that the straight sleeve will eventually crush to resemble the sleeve on the left in the picture?

I believe the rear end is out of an '86 and is a Salsbury, or however ya spell it. By the way, the seal surface is 1-7/8" in diameter. Can I order them from you ?? or if not, where ?

Thanks again for ya'll's attention. Ain't this internet just GREAT ?!?!?!

IT had crossed my mind to put it back in the press and very very carefully give it a kick first to start the crush.

Thanks, William and Dick...

The thing is, there is NO bulge in the new sleeve, and that's what concerns me. EVERY YouTube and pictures that I've researched in a number of hours of trying to gather information shows that bulge in the sleeve in "other" applications, mostly pinion sleeves.

OH, here's the other thing. The guy I bought the parts from now says he has no more seals. When I asked him for "just a part number/manufacturer", he said he didn't have that information. Does anybody know of the "over the counter" part number for the seals. OK, so I screwed up the first seal when pressing it in... my follower is a tad too small...

Thanks loads, guys...

I was mixed up on the crush sleeves and was thinking about the pinion one. The side axle ones do not have a bulge when new. It does take a lot of force to initially crush and the threads on the nut can strip doing so. I usually start the crush in a press. There are two varieties of seals depending on the year of the axle. Parts numbers are JLM-1264 for the earlier one and JLM-12138 for the later. There is a difference in the diameter of the sealing surface which makes the difference. Mix them up and you will either have a big leak or burn the seal from being to tight on the shaft. BTW: just for curiosity, why are you stuck on getting your parts in Austin?

Thanks.. so you are saying that the "new" crush sleeve is "supposed" to be a straight cylinder and they will ultimately "fold" ???? Actually, this afternoon I decided to take it all back apart after I had torqued the s&%* out of it, as it seemed to have bottomed out and did not want to go any further. When I took it down, it DOES appear that the sleeve has a nearly imperceptible bulge on the outside...

hmmmmm

They are correct, they are crush sleeves and you are supposed to crush them. There is a facrtory way to do this and it is all in the workshop manual and the tools are likely avaiable from the club. BUT, there is a simple way also. This entails rotating the hub in the housing when you have removed it from the diff,. turn it and feel how tight it is to turn,( the drag). You then assemble the new one and tighten the nut, checking the drag as you do so, until you get a similiar drag feel as the original. But, as you already have it disasembled you have two options, fit the old sleeves hoping they were the correct fit, or use the new ones and tighten it until you just feel a drag when you turn the shaft, As you can see from the originals they have to crush a long way and the hardest part is starting the crush, once is begins it is easier to continue.
