I knew my wife's blazer had a wheel bearing going out but I had to get her '01 crewcab going first so she would have something to drive on the mail route. Put new Tom's Axles and wheel bearings and seals in the crewcab and started on the blazer.
The right wheel was the one that was bad. I planned on putting a repair bearing (offset bearing) in it with the better of the two axles that I took out of the crewcab and order two more Tom's Axles with new bearings to fix it right later when the parts came in. The wheel bearing was worse than I thought. Metal shavings everywhere. I pulled the differential so I could flush out the shavings and found this.
I figure the shavings got into the carrier bearing and started eating on it also. The left side bearing was fine. My thinking was that if I pulled the differential and the bearings were ok and I didn't mix up the shims, then I could flush out the axle tubes and put it right back like it was and every would be fine. I should have checked the backlash first but didn't have a dial indicator. I will buy one this week.
My plan now, since I have to replace the bearings, get a detroit truetrac differential with new bearings. Pull the driveshaft and spin the pinion gear hoping that those bearings are still good. Put my ring gear on the truetrac and install, shimming it to get the spec on backlash. I sure wish I knew what the backlash was before I started. Put new Toms Axles and wheel bearings in it and hope it works.
Honestly I am in over my head. Someone tell me all the flaws in my logic.
