when I turn the wheel to full lock, and turn my tires squeell across the ground. (mcgaughys spindles) normal or need an alingment?

 

If you did the spindles and didn't have an alignment, it should be aligned anyway. It may or may not help the squeal though. When I dropped my truck via keys, my camber went -1.5 on both sides and it was toed way out.

 

it will squeal a little bit at full lock. the geometry is off with the angle of the tie rods, causeing different movement between the two front tires. mine does it too, even after having it aligned, but im not running the mcgaughy spindles.
