The front end worps the rotors:
4x4parts :
replaced the springs, bushings, flex-lines, rotors,wheels ,tires, ti- rod end, steering stabilizer shock.
Ck'd: proportional valve( It leaks when lines are disconected)
the calipers (The pasenger side did not leak)Bendix
Prob.: The truck shakes from side to side & evetually worps the rotors
Thanks for any help!!!!
