Looking good!.

How did you shim your diffs? I spent one and a half hour to find the sweet spot of shimming my lst diffs, I came up with this for my diffs, yours might be different:

I removed all the shims that was installed in the diffs, inside and outside the bearings maybe there was one on the pinion too, I don´t remember.

If I shimmed the pinion and not the ringgear there was some "unsmoothness" in the diff, a slight resistens, didn´t feel good. I tried alot of different shim setups, from 0.1mm to 0.5mm.

I removed all the shims on the pinion and shimmed the ringgear insted, when I did this I could shim the diff really really tight and it still turned butter smooth!

I have absolutley no play in the diffs, its not possible to move the pinion in and out in the diff case at all and you can feel each tooth on the gears while turning the diffs by hand, but they are very very smooth, the difference from the stock ones isn´t even comparable.

I have now used this setup for about 20hours with my slipper completly locked ( with screws not just tightned the nut ) I am not gentle on the truck and didn´t get the stock diffs last half the time I have been running those.

So I suggest that you try to shim the ringgear only, or maybe you have already found a descent shim setup?

Have you checked if the truck still binds if you lower the rideheight?

I wanted my lst shafts to go as far in as possible in the drivecups, so when I used Lt rockers with Pushrods setup for p2 rockers in the innermost hole in the a-arm it did bind alot, I just screwed out my pillowballs half a turn and problem solved.

I hope you get things sorted out. Good luck!
