The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - 1971 differential bearings?

yeahsee · 10-21-2015, 02:57 PM

My truck is a 1971 with a 12-bolt differential. The SPID lists G80 rear positrac axle.

I want to change the rear wheel bearings, seals and the pinion oil seal and would like to use the best quality products available. I have heard great things about Timken products.

Been looking around on the Internet and been to NAPA etc but I could use some advice on getting the correct parts. The guy at NAPA wasn't clear on what I needed. Rockauto lists the bearings for a DANA/Spicer rear end (#387A) and also the Timken (SET36) with no diff manufacturer listed. Are these correct for my differential?

Any help/suggestions are greatly appreciated.
Thank you.
