Im looking to improve steering wander on my 05 ex. From what i understand ill need to adjust the caster to about 5 degrees. Is there any best practice to accomplish this? Use the shims that mount underneath the leaf back? Or is it better to use the moog caster bushings?

I will likely adding V code, C codes in the next few months

 

It all depends on what your alignment numbers are currently. I used shims on mine but I was replacing the leaf springs anyways.

 

I'd use the shims for gross adjustments like 5 degrees, and use the bushings to fine-tune sub-degree adjustments for good alignment.
