If you install both washers you have too much positive camber without any shims.

I recall grinding the convex/concave area until it was flat on one side of some shafts. I don't recall the parts combo used but remember doing it on the table/bench grinder @ work.

I'll look @ my stuff & see if I can jog the memory (I think it was on my dually).
