Hey, I have an issue with a 10 bolt I purchased. J bought it because it had 4.10s but after installing it, it howled like crazy. Pulled it back out and it turned out the inner pinion bearing just slid right on and off by hand. Decided to replace all pinion bearings and races as well as a new crush sleeve. When tightening the pinion I noticed as soon as I put the yoke on there was nino play in the pinion and once I started tightening the nut I got a ton of preload before ever starting to crush the sleeve. What's the issue here? I'm guessing this is why it made so much noise before. Is there a taller crush sleeve I need to use or what?

Thanks
Greg

Nope, only one size. You are using a crush sleeve and not a solid collar correct? Only other reason would be something improperly machined or a pinion race not fully seated in the housing.

Nope no solid spacer. And yeah everything is fully seated. So confused with this thing.. 93-99 use same bearings correct?

82 and up use the same bearings

coon hunter

That's what I figured. Don't know what the issue is. This is everything I have for the pinion.. minus the seal

Based on the amount of threads I can see out the top that sleeve is already crushed too far. You need a new one.

That's a new sleeve from Napa. Which is what makes no sense to me. maybe try another? Came in a pack of two.

When I tighten the yoke it gets so tight that it is hard to turn the yoke at all. Doesn't make a lick of sense lol

The sleeve is too short. When you tighten a new sleeve, its starts with no load so the yoke free spins. If yours is tight its passed being crushed.

coon hunter

Figured the damn sleeve has been my issue.. I'll try and buy another one from somewhere else.. hopefully it does it

coon hunter

Although it doesn't make sense for that to be the issue either.. even the old crushed crush sleeve dkes the same thing.

Think about what you just said. The old crush sleeve is already crushed. The new one should be noticeably longer. Is it?

coon hunter

Not a whole lot bigger.. but bigger

Can you post a pic of the old one and new one side by side? I could get you a measurement of what they should be later tonight

Get the #'s on the bearings, make sure they are the right ones

coon hunter

Already checked the bearings on napa's website and they match up..

01ss I went to another store and they had the same crush collar that I have.. wonder if the idiot before me put the wrong year gears in.. how long should the pinion be?

coon hunter

Mine measures to about 8.25in

coon hunter

Wrong yoke?

According to this site there should be a shim or something under the crush sleeve? But how big is this shim? Would it even make a difference with my current issue?
