The mounts are hard to inspect when they are installed in the car, the rear mounts seem to be more highly stressed. Look for deformation of the rubber pieces that hold center metal bushing in place. On my car the rubber had ripped over about half the surface area. This kind of failure would cause the control arm to shift and alter caster or camber (or both)
My car also had a bit of uneven tire wear that I'm hoping the bushing replacement solved, I didn't check the car on an alignment machine before the replacement but I did have an alignment performed at the dealer after the repairs and they set the toe-in and said everything else was "perfect".
The car now tracks better than ever, dead straight and it seems to have a stronger 'on-center' feel. It's a noticeable improvement.
Time will tell I guess.
I'm sure there are other bushing available, I can't really advise you about them since I only use OEM parts when I do repairs.
