Yes, DIY alignment is time consuming and requires patience, but once you get it set correctly it should hold. I can read my inclinometer to about a quarter degree and I adjust both sides to the same interpolated readings, and as I said previously when I had my 190 checked on an electronic alignment rack the readings were within 0.1 of what I had recorded as final numbers when I realigned the front end.

After I took initial measurments, I just set the all the pivot bolt to their extreme outboard position, which will yield maximum negative camber and maximum positive caster, then I backed the high camber reading down to the low reading, then did the same with the caster and rechecked everything, Once I was satisfied that I had maximum neg. camber and max. positive caster, equal on both sides I torqued the bushing bolts. Be sure you do this at normal ride height.

The final adjustment was toe.
