Title: Procedure of removing shims from upper control arms
Post by: jimandemma on September 06, 2017, 05:56:48 PM

Hi all,
         after lowering the front of my 75, I have around 2 1/2 degrees negative camber both sides. On the upper control arms, there are two 1/8" shims front and back on both sides. To obtain close to positive camber again, can I remove these shims by loosening the nuts with weight on wheels, or does the car need to be jacked and wheels off?

Thanks in Advance,
                              Jim

Loosen the nuts and pull the shims out, do the nuts bach up tight

do you have a caster gauge.
Camber you can do with a level.

No caster gauge Bfit. Will probably take it to a wheel align shop. Caster is currently 3 1/2 degrees both sides.

yeah, happy with that caster, just want to get a bit more positive camber to bring the top of the tyres outboard. So I can do shims with weight on wheels?
