Re: 10-bolt solid crush sleeve? doesn't prevent flex...but it keeps the pinion from walking.
I can't think of anything that'll keep a 10-bolt from breaking...they are just too small to transmit that kinda power <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

Re: 10-bolt solid crush sleeve? The only reason for the crush sleeve is to keep the pinion nut tight as the bearing starts to wear.
That's it!!!! When accelerating there is no pressure on the sleeve.

Re: 10-bolt solid crush sleeve? Actually, the crush sleeve pushes the two pinion bearing apart. This keeps you from overtightening the pinion nut and having too much pressure on the bearing races. The crush sleeve itself is a thin piece of steel tubing with and bulge for the spring effect. The solid sleeve is at least 1/4" thick and fits alittle closer the the pinion. You add shims to get that same distance from the two bearings. This is determined by a certain amount of drag torque while turning the pinion. The solid is less likely to compress and cause the bearing to become lose and break the gear.

Re: 10-bolt solid crush sleeve? I figured it out after I tore my rearend apart. I wrote the post before I ordered the part. After I saw what it did, I thought I should share it with everyone else that asked. I wasn't trying to show my intelligence. (although I am pretty smart <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> )

Who in the hell do you think you are? What is wrong with someone asking a question and then coming back and telling everybody what they have learned? Maybe there right maybe there wrong. Everyone is entitled to the opnion of how things work. If I remember correctly you are the one that said a MTI 422 cost $18000. <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" /> " WRONG"

Re: 10-bolt solid crush sleeve? The solid crush sleeve comes with shims. The best way to find the correct shim stack is to take out the old crush sleeve and measure it with a micrometer, install it with the shim and check the drag torque make sure it isn't too tight. If you install a new gear and/or differential, you need to crush the new sleeve and use it for a starting point. The way I see that the solid sleeve helps is it keeps the bearing distance the same which in turn keeps the bearing coming loose. If the pinion walks around and misalign it would cause a breakage. I haven't raced on it to get a breakage, but the concept is good.
