can anyone show me pix of the crush sleeve? where does it go exactly? I assume its either inside or outside the inner pinion bearing, but where exactly?

COOL! THANKS!

is that picture from an FBody? Because my new crush sleeve is the same length on each side of the center bulge. It also answered my question I forgot to ask - do you install the bearings dry or should you use some type of pre lube?

Nope, that appears to be from a small differential. Notice the very small pinion gear.

If I remember correctly, the 10-bolt crush sleeve looks like you describe it, equal distance with a buldge in the center.

Always lube the bearings when installing them, soak them in gear oil.

Crush sleeve goes inbetween the two pinion bearings. It doesnt look much like the one shown above. It does however look exactly like this one:

whats the best way of holding the pinion/yoke while tightening the pinion nut? the rear end is in the car and the car is on jack stands, not on a lift.

If you have a friend with a machine shop borrow a tool that looks like this:

Or fabricate something that looks similar.

I built something simliar to this



Found this on ebay. I would say it's pretty safe since it bolts on instead of sliding on.

I've seen tons of guys use impact guns to tighten down the yoke, checking it every few seconds with a needle torque gauge to measure turning torque. As long as you do it progressively, it works pretty well.

However, if I was setting up my own rear and wanted it exact, I'd prefer to have a torque wrench and holding tool, like the ones that were posted.

is there an inch/lb spec for turning the whole rear assembly? I've seen the secs for turning just the pinion.

I'm thinking the whole thing reassembled and using the parking brake would hold it just fine. But what spec would I be looking to get turning the whole rear with axles? and would that be with or without wheels?

20-25 for just the pinion, then shoot for around 40 or so with the posi in place. Thats with all new bearings. With used carrier bearings I have found the posi can actually move back and forth (left and right) from the bearings being worn. I will slip very thin shims in place until there is no excess play and there is very slight side loading on the carrier bearings. Dont go crazy if they are used. Just a tad to snug everything up. On used bearings I would look for about 25-30 in/pds total. No need to measure with the axles in place bc those arent the type of bearing that need to be loaded.

yeah but the point is to have the axles in place with the brakes hooked up to help hold the whole thing from turning while tightening the pinion nut.

Thats not how you measure it though man, gonna have to figure something else out. Do you have an impact?

01ssreda4

Do it right, or you will surely be pulling it back apart from pinion bearing issues

thanks for your patience.
yes, I have an impact. I'm just not sure it has enough ***** to torque it down. How much torque does it take to crush the sleeve?

A 24 inch prybar fits perfect in the yoke with the big socket on the pinion. Have a buddy hold the prybar and someone else with a long breaker bar and teamwork. I have done this many times. Impact gun will do it too but you have to be patient, and buy a couple crush sleeves bc you wont get it right the first time....

I have had some crush sleeves that started crushing pretty easily, some I cussed at for an hour. Seems like they are softer or firmer depending on manufacturer.
