Such a maneuver loads the DS front. DS front is the one with the wonky caster.

If the DS caster is not the same as the PS caster for any reason, the car is going to pitch a fit. Kinda like when you get the bad grocery cart with a bent front wheel; where the one wheel just kind of vibrates along. The fit might be induced either because the car has a dynamic caster change induced by the turn or from unloading the inside wheel and transferring all of the load to the one with a different caster setting.

If it a dynamic issue, you wont catch it with a wheel alignment. You will need to put the car on a chassis rack and make sure that it is square. Assuming that it is, you then need to find the bent part that is causing the caster number to be off.

If your alignment shop shoed you out the door with an out-of-spec caster value without bothering to figure out why it was out of spec, then you need a new alignment shop.

Tire wear might be a clue also, but rather than wait for a tire to wear out, go buy a cheap laser thermometer and after a good run down the HWY, pull over somewhere safe and see if there is a noticeable difference in tire temps.

What is Ds and Ps ? Thanks again for the insight
