Differential Gear Thrust Washers

Posted by Joe On 2024/4/17 20:48:06

Hey all. Working on a 23rd series, Ultramatic, 3.54 rear end. Pulled rhe carrier to replace the gasket, copper wire rings, and clean everything up. Upon inspecting the internals, I found one of the differential gear thrust washers isn't seated properly between the bearing and gear, and on the other side, there's no thrust washer at all. Pinion thrust washers are both in tact. Diff made no noise, and no metal in the fluid. Just seems unusual, and parts book shows each gear having a thrust washer. I do know there were varying thicknesses to the washers, too.

Want to get several opinions here... should I get this rebuilt, or would you run it? Or is it easy enough to to replace the thrust washers, and I could just do it myself? I would think I would just have to follow the manual procedure for up until I hit "Drive Pin Removal," which, theoretically, I wouldn't have to do to replace the thrust washers. Question of course would be washer thickness.

Thanks in advance your advice and experience.
