Even if you do have an impact bad enough to crush the sleeve, which I doubt.... dont use it!
Once the sleeve starts to crush that badass impact will most likely over crush it, pinion pre-load needs to be really close.
If you over crush it, the sleeve is garbage and you can expect to smoke a coupe of pinion bearings if you run it to tight, which will also fry your gear oil then the gears...
Enjoy your day

 

This is why I'm a forum member.
I'm just hoping its only one day

 

Good luck man my head is already spinning and I am not even there. Sorry I can't be there to wrench with you it sounds like its going to be interesting for sure. After reading the other posts installing the lifts we did sounds like like a walk in the park. Keep me posted.

 

You will be missed but it's honestly not complicated. Just need a lot of patience...

 

How is it going? Did you jump in this weekend?

 

Did my install yesterday. It was.my first install but it went well. The only issues was the bolt for the ring gear. Other then that we didn't use a case spreader. And I made a pinoin hold back tool. We used and impact to get our pinoin bearings set. Then used a huge beamed bar and pipe to get the crush sleeve to crush. It was a fun job. If you are very good about following steps and thinking logically its not that bad of a job.

 

I did and I have to say that I hate crush sleeves. Holy crap it takes a lot to crush one. The only issue I had was pinion nut related. It's a bitch to take of and a son of a bitch to put back on :-) everything else was cake work...

 

Glad yours went well.

 

Good to hear yours went so well. Maybe in a couple months I can bribe u with beer or booze to help me do my gears.

 

Let's make sure these don't have any issues first :-)
