I Have A 1999 Ford F-150 & My Problem Is My Steering Wheel Shakes Back And Forth At 63mph & Up. I Have Gone Completly Through The Front End. I Repalaced All Tie Rod Ends, Upper A Frames, Lower A Frame Bushings,ball Joints, Anchor Pitman Arm, Steering Gear Box, Steering Gear Box Arm, Power Steering Pump.hade The Rotors Milled, New Ceramic Brake Pads, The Tires Balanced 2 Times, 4 Whell Alignment. I Also Took It Out On The Freeway, & Got Up To The Speed Thats The Steering Wheel Shakes Put My Truck In Neutral & The Steering Wheel Still Shakes. Please Help

 

I've had steering wheel shimmies b4, and it was a bad set of tires. It wasn't that they were out of balance, it was that they were defective.

 

I Thank You For Your Comments. I Have Hade The Problem On Old Tires & I Purchased New Tires & Have The Same Problem Thanks Again For Your Inpuy Bill

 

probably tried these but thought Id mention..
Checked for a bent rim right? rotate the fronts to the back?
try to find a buddy with similar size tires /wheels and borrow em.
still sound like tire or wheel related.
GLuck

 

Do you have aftermarket wheels? The factory rim is centered on the hub with an o-ring. Some aftermarket rims use the lug nuts to center the rim. Are your tires real wide? I have also seen wide tires cause this. Usually a steering damper will cure it. Also if your truck has alot of miles on it, the steering gear could be loose or the steering shaft/joint. Hope this helps.

 

NO I HAVE THE WHEELS THAT CAME NEW WITH THE TRUCK I DONT HAVE ANY O-RINGS WITH MY WHEELS. I HAVE THE SAME SIZE TIRES THAT CAME NEW WITH THE TRUCK. IHADE THE STEERING DAMPER CHANGED. I ALSO HADE THE STEERING GEAR BOX CHANGED. I THANK YOU FOR YOUR IMPUT BUT I HAVE DONE ALMOST EVERY THING TO FIX THE PROBLEM BILL
