I have a '03 Ranger 4x4 with 165K miles. I've put all but 7 of those miles on this truck. It's time for some work now. The front end seems to wander a lot, but nothing feels loose. The shocks are fairly new (about 20,000 miles since they were changed) and the front bearing hub assemblies were changed about 10,000 miles ago. There is an unusual amount of tire wear on both the inside and outside edge of the tires (both tires show the same wear, and it happens quickly as in starts showing after 5,000 miles on new tires the psi kept between 32 and 35) This problem started at about 135k miles, and I'm tired of guessing and being told that nothing is wrong by mechanics. Any ideas or thoughts?
