My 4A IRS has the shims on the rear trailing arms that I believe it was
delivered with. It supposedly had a 4 wheel alignment 10 years and 4 thousand
miles ago. I just installed the goodparts rear axles and adjustable trailing
arm brackets. I have set the camber to about -0.5 degrees on both sides.
I used the "string" technique to check toe because it looked by eye to be
excessively toed-in.
I ran the string front to back at a small distance out from the center of
knock-off nuts on the wire wheels. I measured approximately 1/4" toe-in on the
drivers side.
Are there any things I need to watch out for with this technique? E.G the
rear track is 1/2" narrower than the front so I might need to have the string
1/4" further away from the rear hub than the front? This is a very small
angular difference but when working at 0 to 1/16" toe-in, that small difference
is meaningful. Compared to the 1/4" I saw, it is a small amount of error.
Any suggestions about how to set the toe with the string method?
And how much change does adding or removing one shim make?
