I have had my truck aligned three times in less than two months. I have replaced the tires, then back on the alignment rack. It pulls to the right worse now than when I started having it "fixed". So far everyone that has looked at it just scratches their head and tells me they don't know why its doing it. I have been to three nationally recognized, and one local shop so far.

My pickup, after hitting a bump at 50 to 70 mph, will vibrate so bad that everything falls on the floor. I have to slow down to 20 to get it to stop. Had new tie rods, rotated tires, adjusted air pressure, and stabilizer shock.

Nothing works

Vibration started at about 17500 miles. Starts at 20mph and occurs at all speeds. Had tires re-balanced, didn't solve problem. Had shocks, springs, driveline, bushings, tie rods and ball and U joints checked at professional shop. All seemed OK. Dealer said it was a throttle body?? problem, and cleaned the throttle body and re-programmed the ECM with new software, none of which has done any good.
