The new (to me) K10's rear tire leaned in ever so slightly. Having seen how poorly the previous owner took care of this truck I thought I had better check it out. After consulting a few people I decided that I should go ahead and order axle bearings and axle shafts. Once I had the differential cover off I saw that the spider gears where pretty well pitted and chunked up too. So I had to order a set of spider gears too. I put the axles and bearings in last week but I had to wait on the spider gears to come in. They finally came in today. I got them swapped out just a little while ago. The last person that was in that rearend was a freaking HACK! All four of the spider gears are supposed to have thrust washers behind them, only 2 had washers and 1 of those 2 washers was in 2 pieces. That is most likely why the gears were chunked up and pitted, they had a LOT of slop in them. Luckily the ring and pinion gears looked ok. I'm crossing my fingers on that part.
The driver's side C-clip was shot too. Here's a few pictures of them.
My fancy new spider gears.
