Crush Sleeve Eliminator

[Kansan]

Hey all, I have a leaky pinion seal on my cuda and am thinking about using the crush sleeve eliminator when I go back together.

I don't have much experience with rearends, so I wonder if it is a complicated process to change out. Also, anything else I need to look at in the sure-grip when I take it out?

Thanks,

Kansan

I just installed a crush elimintor, and its the first rear end I've torn apart. Its not too bad, plenty of you tube videos out there to help. Just remember to ADD shims to loosen the rotational torque,and to remove shims to tighten. Took me quite a few attempts to get it set just right, so be prepared to install, take apart, reinstall and take apart, etc unitl you get it right. Take a measurement of the old crush sleeve to get a ball park dimension, and set up the crush elimintor with shims to same dimension for a starting point. Also, according the manual, if you are using the same inner bearings (although everything i read said to replace the outer bearing no matter what, and I did), to get a rotational torque before disassembly and get a rotational torque 10in lbs above that......i did not do that, so I had to guess. New bearings in both positions require something like 20-35 according to manual.
I removed everything from my case, so today's project will be setting the backlash on the pinion/Drive gear set. You might have to do the same.

If you are prepared or intending to strip the diff head they are a good idea.

If you use Timken bearings, you can take your old one and have the ID opened up to where it will just slip on and off rather than need to be pressed. You will probably need a machine shop to do it. That should get you very close if not correct. Then when you press your new bearing on, you can check to see just how close you are. You might be good to go. But even if it isn't, it should be very close and will still save time and effort.

Used to, the Timkens were consistent enough that that new ones would measure the same as the old ones. I don't know about today. I haven't set one up for several years.
