This is my first rebuild on an 8 3/4. I've done 7.25, 8.25 and newer corporate diffs. I have the tools for this operation. I'm installing Dr. Diff Powr-Lok, carrier bearings, pinion seal and inner axle seals. I am using OEM type bearings. I'm keeping the same gear set. Is there anything else I should replace? I didn't plan on replacing axle or pinion bearings since they turn smoothly. Does swapping the carrier effect the the pattern?
