1971 differential bearings? - help needed
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. |

I like RockAuto, but you need to know exactly what you need/want. The link above is good and use the phone to call them, tell them what you have, and place your order.
The 12 bolt is NOT the Dana Axle.

Timken or Bower (Federal Mogul) are both US made.
