I have a 2004 QC 4x4, 3.7l with a 5 spd and a 3.55 geared 8.25" rear axle that must be rebuilt due to horrid pinion bearing grindage. I'm all but absolutely certain I'll need a new ring and pinion along with the master bearing kit. Is there anything else that I will need to replace?

If it isn't, and being you will be in it as deep as you are, install a limited slip diff.

Im doing this to my 9.25" this summer. You might as well replace the axle side bearings and seals while you're in there.

Good luck with it

Update: Update: Picked up a replacement rear end yesterday. It's a year older and has a few more miles, but there's no bearing noise, no gear noise, it functions as intended. It's an LSD, and it was only $210 (+1.5 hrs.), which makes a Detroit TrueTrac a far more feasible option for my budget. Putting an 03 with 180k on my 04 with 177k. Isn't that the definition of counterproductive? Lol.
