Alignment question
I know there are people here who do their own alignment.
Let just say, for the sake of this example, you check the rear and there is 1/8 toe out and ¾ degree negative camber.
So you set the rear to 1 degree negative and now set the toe to 1/8 toe in. Will the camber change?
I watched a mechanic, and I could be totally wrong, but he set the camber, then the toe and the camber changed slightly. There was a bit of back and forth. Is my memory faulty and is there a bit of back and forth???
In the rear only or in the front too?? Is my question clear?

On the front, of course, you have all three. To adjust caster, one adds (or removes) shims to either the front of the upper A-arm attach point and, typically will also remove (or add) shims on the rearward attach point. As these shimstacks also control camber, it is not uncommon for the alignment tech to do a bit of “back and forth” as you state.
The effect on caster and camber as a function of adjusting toe depends on the inclination of the spindle axes. Others who are more accomplished at doing their own alignments will have more input on this but generally speaking for a daily driver, any change in toe will have de minimus effect on caster and camber.

depends.
a lot of ways to skin a cat.
when C-3s were new, no fancy computer read outs and rear was treated like front by the way car was "loaded" on align machine.
basically car was backed on and aligned.
like standard cars were rolled forward on for front align.
I can't picture the extreme effects on toe when camber is changed a little.
sounds like the guy you watched was at least diligent in his work.

I agree about the search engine here. The thing about YouTube video's, that you have to be careful about is people post stuff that isn't correct.

How are you measuring your camber now? Would you not be able to measure again after you adjust?
I'd assume a tiny change, but easy to measure and set precisely with heim-jointed strut rods.
