Thread: Need diagnostic help on SEVERE steering wheel shake

Tweet

I reread your original post and you said you had it aligned. What specs did they use? Reason I ask is that I think I remember seeing somewhere that if your MMII suspension has power steering they like a little more caster than a stock Pinto/'MMII would call for, something like 3 degrees, I think. Could it be that when you changed the coilovers you also lowered the front end, which would reduce your caster? Insufficient caster can cause some goofy handling issues, like you describe.

Looking at the paperwork, they used the specs from a 1974 Mustang. I did lower the front end, when running 155.60.15's, but since have raised it back to original height & I put on 185's yesterday.. problem still evidenced this morning.
Any possibility that the problem is related to the caliper's? though I see no scoring on the disc surfaces... just a thought.
