I'm attempting to 'crush' a new crush washer while setting up my 9". I have the pinion nut at about 250 lb-ft of torque and the crush washer hasn't even budged. In fact, there's play in the pinion in between the bearings...

Any thoughts on what I might be doing wrong while setting up the pinion?

I suspect if I put it in the 'crush-o-matic' I'll blow past the 'knee' of that crush washer and have to start over!


Anyone else?

Took me more than the 400 ft/lb rating on the impact wrench - we tightened it, (I say we, but I didn't do that part
) but couldn't move it any more, and hit it with the impact - didn't move.

So, we bought a longer bar. I estimate 500 ft/lb on the pinion nut before the preload and drag were correct.

FE: Yes! Crush sleeve...

King: Sounds like what I have to do next! Big breaker bar...

I think you can put the sleeve by itself in a press just to help get that initial breakover compression, and then put everything back together and save yourself a little bit of strain. They are a pain.

Just get a solid sleeve and be done with it. I had several different sized made up at a machine shop. Anywhere from .445 to .485 in. thickness. Just set it up with the right one and set your shim thickness and be done with it.
