In Reply to: 1953 NAA SHIMS SET BACK LASH ON WHEEL BEARINGS posted by Kevin on December 05, 2021 at 14:44:50:
The only way I found is scientific trial and error. Take a guess on a number and install them. Now test.
With both rear wheels off the floor. Turn one rear wheel.
If the other one turns in the same direction you need to add shim(s).
If the other one does not turn or turn in the opposite direction, take out shim(s).
A PITA but that is the only way I know.
