I want to pull the diff to double check backlash and would like to try and figure out what one was in there originally. Has anyone measured the stock shim and could tell me how thick it was. I assume they use the same thickness at manufacuring but I could be wrong. Link to comment Share on other sites More sharing options...

You will need to measure your shims and sort them from thick to thin so that you use the correct ones to get your backlash.🤔 Link to comment Share on other sites More sharing options...

The issue is when I flip the 4x4 switch you can hear the front diff. Hard to explain but you can tell it's in 4x4 vs 2x4 , not turning but straight line down the road. So my thought was to put factory shim in and see what backlash is, not sure if tou get more noise from a looser or tighter backlash. Link to comment Share on other sites More sharing options...

Are the tire sizes original or did you change them if yes are the fronts the same diameter (height) as the rear. I don't run in 4x4 except in the deep and on the soft trail I run in front and rear engaged but both in the open position that way I minimize the cornering effort and front to rear difference in tire size. My front tires are slightly taller than the rear even though they were ordered the same but are supposed to be different in width only. You can check out my build thread from 2019 if you need more info?🙂 Link to comment Share on other sites More sharing options...

I'm working on pulling the diff to double check everything and have a look inside. Link to comment Share on other sites More sharing options...
