So, I've been driving around in my '62 C10 and I noticed a vibration coming from the drive line. I figured U-Joints, but when I crawled under the truck this morning, I found I was wrong. There is a lot of slop in the pinion. I have never taken one of these differentials apart before. I know that with the third member, these are a lot easier to work on. I won't have to pull the entire differential and axle housing to fix it, just the gear cluster. At least, that's the way I understand it. Please correct me if I'm wrong.
I still have the factory 3.90:1 non-positraction set up. I know that now would be the perfect time to upgrade to the 3.38:1 setup, but I'm on a budget and I actually like the 3.90:1.
What are the chances that I am only looking at a rear seal and probably bearings? What other small consumables am I looking at?
I'm pretty good with the mechanics ( just rebuilt the engine with no snags), but I'm not sure I have all the tools I need for this job. I could probably borrow what I don't have though. Is this something I should attempt, or pull it and take it to a shop?
