Pinion Angle Adjustment

[donutninja]

The car's been lowered for little over a month but I still need to get the pinion angle adjusted especially since it's a pretty dramatic drop.

I've been calling around but no shops will touch it. (Firestone, NTB, local garages) Is it crazy to call up Ford and see if they'll adjust it since the car is still under warranty? Or do ya'll know of any shops in the Carrolton/Coppell area that can adjust the pinion?

It drives fine but I'm hesitant to drive it harshly until this is adjusted.

Also, I did a forum search and didn't really come up with much and not sure if this is in the right sub-forum. It's sorta suspension related.

thanks!
