On the alignment adjusters... (for when you get an alignment)
 

When the camber has been maxed out in the front, the lower control arm's inner, forward bushing adjuster, will be positioned so that it pushes the A-arm out as far as it will go - that means a 3 o'clock or 9-o'clock position, depending on how you look at it.

If the shop says "it's maxed out", but the above isn't true, point it out.

The forward adjuster adjusts mainly camber.
The rear bushing adjuster, adjusts mainly caster.
There is only some interaction between them.
Adjusting either camber or caster, will change toe, so toe needs to be adjusted last.


In the rears, turning the adjusters in the same direction, will change camber.
Turning them in opposite directions, will change toe.
