:confused: hey- was wondering if anyone has any ideas on how to help me out- have a 87 chevy 1/2 ton 4x4- suddenly developed a nasty vibration--put new rotors - calipers- steering stabilizer- changed tires- checked ball joints-tie rods-steering box- also new lockout hubs- runout on new rotors was .005 drivers front--.015 pass front-- is .015 too much- is that the problem?? any help greatly appreciated. :D

have you had your alignment done, and your tires re-balanced? when you change tie rods and ball joints, you should to get an alignment done...

Maybe u should look at your universals and shafts?

it was the rear parking brake on slightly- strange though---but it is gone!!!!!!!!!!!!!!!!! thanks for the help--
