Bearings & Seals???

[gpd4]

How can I tell which bearings and seals are in the rear end of my 85 without taking it apart? Every part store I've been to has told me that there are three or four different sets that will fit in the 12 bolt rear end. I'd really rather have the parts on hand when I start this project. Any help would be greatly appreciated. Thanks.

If I pull an axle and get the seal number, will that give me enough info to get the bearing numbers?

Try the dealer. They use your vin for parts. It's worth a try.

Unless you swapped the rear end it should be a 10 bolt in an 85.

My Chevy isn't broken, its just out of gas.

It's definately a 12 bolt rear end. I had it "rebuilt" last year when the pinion fell in and threw the drive shaft and all that. I don't think I got anything more than a new ring and pinion. The bearings lasted about 10 months after the rebuild, and the lube seems a bit metallic these days. I've been putting this off for too long, and it's starting to whine a little louder these days. It looks like I'm going to have to dive into this blind and get the numbers from the source. Too bad it's been so cold here...it won't fit in the garage!
