I took my sterling 10.5 apart about 2 months ago, been going through a divorce and just recently tried putting it back together. Now I can't remember where the crush sleeve is supposed to go. The only way I can see it working is if I put it on top of the outer pinion bearing against the yoke. But it just seems that the yoke sits up to high. Can someone help me with this?
 
dont know about the 10.5 but on other diffs the crush sleeve gos between the 2 pinon bearings, this way it pushes both the pinon bearings out of the race, that is what gives you your lash and keeps it there
 
yeah, I know, that's why I have the problem I'm having, it doesn't contact the outer pinion bearing, I've got a good ways before it does and there's no spacer at all.
 
Then something's wrong. Both races are fully seated, both bearings are fully seated, and it still doesn't touch the crush sleeve?

That said, the crush sleeve is the source of most problems with that diff. I would put it back together with a solid spacer and shims.
 
crush sleeves on all diffs go between the pinion bearings to seperate them. if you put it in and the yoke seems to high its probably b/c its not crushed. Crush it load the bearings with 25 inch lbs of preload if they are new bearings.
 
I never pulled the races, I just pulled everything apart to inspected the bearings. With all the bearings, races and everything properly seated, the crush sleeve still doesn't contact anything. I double checked the old sleeve with the new and they are the same. There isn't a spacer or anthing I may have lost?
 
I don't know.... it's possible?? I don't remember. But w/o seeing it, I'd be just as likely to guess that the front bearing isn't fully seated on the pinion shaft. It's an awfully long way between those two bearings. I guess anything's possible.

If these are used gears, I would seriously consider a solid spacer. You'll pull the threads on the pinion trying to crush a new sleeve. BTDT.
 
how do you know the crush sleeve is not touching, the bearings are already tight? the outer pinion bearing is a press fit or at least interference fit.
 
The inner pinion bearing is fully seated on the pinion. The outer pinion bearing doesn't press fit anywhere, at least not how I see it. When the bearings are tight I can pick up the pinion a good 1/2" or so. It's been a 2 weeks since I've messed with it, so I'll revisit it again tomorrow night and see what I'm doing wrong.
 
lol! ok, I'll give it a shot tomorrow afternoon. Thanks for the help!
 
The crush sleeve is just that, you have to crush it to make the preload, crush too far and you need to start over ( with new crush sleeve ) once it starts to crush ,it goes quick and it is very easy to over load the bearings.

A solid spacer and shims is the better way..... but there is still a lot of measuring of preload, and shim thickness.

If it were easy, everyone would do it !
 
Ive researched the spacer/shim for the 10.50, you have to use 2 9" spacer kits to get itgto work for the 10.50. For that price right now I'll stick with the crush sleeve.
 
Well, here's the issue, The yoke runs out of spline on the pinion before anything contacts anything. That's what the problem was. . . help?
 
Is that the original yoke with the original gears?

There are two different pinion/yoke designs. Possible you have them mismatched if either part is new.
 
yup, it's everything that was originally in the axle, I just took everything apart to inpsect the bearings and races. Sat there for a while yesterday and just can't seem to figure out what I'm doing wrong. . .
 
nobody? nobody has a guess? I'm straight lost on this. I have no idea what I'm missing here. . . .
