Ok, I have been searching for somwhere to post. I have posted here several other occasions. Everyone is always a great help. And, this is a pretty generic question.
My brother has a '86 Jeep Commanche. 4x4 4cyl.
There is a vibration in the front end. Usually only at highway speeds(55-60mph).
I just wanted to know some general ideas of what could cause this.
He has checked the alignment, and wheel bearings. Wheel balance.
Only other thing I can think of that may contribute to a vibration is an over\under inflated tire.
