I am rebuilding my rear axle, and I have a question about shimming. I saw online that when replacing pinion bearing, there is no need to reshim the pinion. So I re assemble the axle, check the pattern on the gears, and the markings indicated that I need to thin my pinion shim. That confused me so I disassemble everything. After further analysis, I saw that the pinion bearing was Koyo but the bearing cup was Timken. Would the different brands cause the messed up pinion depth? I destroyed the bearing pulling it off the pinion, and went ahead and ordered a Timken bearing to match the Timken cup. Would this need reshimming too?
UPDATE: The answer is yes the difference in brands does make a difference.
Both the cup and the bearing were brand new but after inspecting the bearing, they were slightly different. The rollers for the Timken bearing were thinner and longer than the Koyo bearing. After putting the Timken bearing in, the mesh pattern was perfect.
NOTE: Make sure to check the branding on both the bearing and cup.
I bought a complete rebuild kit for the axle from summit, and failed to check the branding for the cup and bearing. They all should be the same brand, but make sure to double check.
Hopefully this can help someone out in the future
