Lower Control Arm Bushings and Bolts

[97C28O]

Ordered a pair of Polyurethane Bushings for the Lower Control arms. Will be replacing the bolts with the eccentric camber/caster bolt, part #2023300118.

My question is, how many of these do I need? There are Front and Rear bushings on each control arm, do I just need one bolt on the Rear on each side? I believe the rears would adjust Camber, wil it adjust Caster as well? Should I replace the Front bolt too? Will there be any benefit to that?

Appreciate the help!

You need an alignment to determine if you need the adjustment bolts. The replacement bolts do not have the ability to use the middle (neutral) setting, so do not throw them away if you replace them. The LPD bushings do have a shortcoming. The small center shaft will cut through the suspension mounting tabs. I modified mine to prevent this, and allow the nut to be properly torqued.

The front bolts are the camber adjustment, and the rear are for caster. Adjust camber, then caster. Then go back and check both.

I have placed 4 new eccentric / camber/caster correction bolts in and was able to get a better spec on the alignment!

-1.6 Camber Front Left
4.7 Caster Front Left
-1.6 Camber Front Right
5.2 Caster Front Right

That is pretty good. I bet if you spent some more time, you could get the caster damn near the same side to side. Having the values equal is better than hitting the factory spec'd value in my opinion.
