I looked at it, but didn't stack them.
Not that they would have went anywhere, they're notched and the captured by the U-Bolts.
Well I started on it this morning and promptly stripped a nut and the U-Bolt looked bad,
so that got put on hold and I had to get some sleep I work nights....
So my loving wife found me two more U-Bolts and I got it put together.
I used the 4* shims and I can say there is a pronounced difference.
Its not perfect but it is very managable now and you can drive it with one hand.
Not both hands on the wheel waiting for it to dart here or there for no rhyme or
Here is the old steel shims I pulled out.
What you can't see is the wear on the these those lighter marks are where the axle has worn into the shims over the years.
If I had to to make a guess these was a 2.5* shim they was slightly thinner than the 4* I replaced them with.
So for the record Its a net positive the driving in circles in the wheel will start returning to straight on its own.
The feel is lighter in the wheel and made it feel almost power steering like when moving.
The lightest move of the wheel effects steering now as it should be, not 1" to 2" of movement
to correct little inflections in the road surface.
I can't say that if your shims was good and flat ramps you would need this with a rough country 2.5" lift.
I never drive my CJ before installing the lift so there is no before and after reflection here.
Thanks for the all the comments. It sure makes one feel better that someone is actually reading this too.
Not just me posting it for posterity.
In retrospect if you need shims I would suggest finding the 2" wide ones for a CJ, I used 2.5" wide wrangler ones
and just narrowed them with the cut off wheel at the U-Bolts to make it work.
