pinion nut won't tighten!!
 

I'm in the process of putting my pinion gear in. I installed new bearings and races, double checked to make sure they were the right bearings and the races were seated properly. The pinion nut drew up almost all the way but I still have 1/32" play back and forth let alone started to crush the crush the nut. I've had an impact wrench on the nut trying, but a small compressor. I have heared these crush sleeves are hard to crush but I'm not quite to the sleeve and it is already hard as hell. I even checked the splines on the pinion and flange looked good. I sure hope one of you guys has a good idea!

Try a breaker bar and a 6' piece of pipe.

Take care,

What PKRWUD said. I also took a 3' long piece of bar stock and drilled two holes in it so that I could put two bolts through the unused holes in the pinion. This gave me a way to hold the pinion still while I cranked on the nut.

Finally!!
 

Thanks guys I was finally able to get the crush collar pulled up and the new bearing preload set. The guys at this site are AWSOME!!!!

I was having the same problem yesterday. I finally took out the 3/4" impact and that made short work it.:D
