Alignment
 

Ive got a 2015 F 350 I use for a feed truck. Very careful with where I drive....no ditches or "off roading" other than grass pastures. Having a terrible time keeping it aligned. 38k miles and it needs done for the 3rd time. They get it straight when I take it in....but getting old trying to keep it from pulling to the right. I keep tires rotated. Ideas?

1st thing to check is sticking caliper. Our trucks need caliper bracket glide pins lubed fairly often. Very common issue.

Ask forr a printout of the before and after specs to see what is changed.
