Well I've been getting parts ready for my regear. I checked the factory settings. Back lash was .001" off at .009". Total torque to rotate was .010". According to all data at work, the total should be .010 to .020" plus at least an extra .007" to rotate with carrier installed and axles removed. Here is picture of the gear pattern from the factory with drag applied, the gears have 13,000 miles on them and im not sure if im liking that pattern when looking at the coast since (since they are not brand new)





And of course I was sent the wrong gear set so I put everything back together, installed a new crush sleeve and set the preload slighty tighter and used lock tight on the original pinion nut. Does any one have any feed back on this? Or am I just freaking myself out?

 

:bump

 

It's not perfect, but I think you are freaking yourself out a little bit. You mentioned your new gear set was wrong so I take you you'll be getting them exchanged for the correct set?

 

Yeah they'll be in a soon hopefully. Im a perfectionist and always triple check and worry about things, I do some rebuilds for high powered diesel transmissions that run pulling competitions so everything has to be spot on and tripple checked. Ive done a few regears, but nothing with crush sleeves. Would setting pinion bearing preload a little tighter have any affect on back lash or pinion depth? Thanks for responding to my craziness haha.

 

Haha anytime. Pinion preload will not have any effect on pinion depth or backlash.

In high powered applications it's crucial to have everything dead on like you are saying but for what most of us are doing we have a little bit of a cushion. Obviously the closer you can get it to being perfect the better.

We're not a fan of crush sleeves either. We actually got a solid spacer and shim kit to replace the one in the 8.25 rear of our XJ when we set it up. Highly recommended.

 

Okay thanks again. Yeah we've used the crush sleeve elminators, makes it so much easier in my opinion.

 

100% agreed. It also assures you the sleeve wont ever crush any more on its own. A lot of the high horse power guys swap in hardened alloy steel spacers.
