My next project is my front suspension and five lug conversion. While driving at a speed of 65 MPH the steering wheel starts to shake violently. But when I accelerate to 80 MPH the shaking goes away. Can anyone let me know what they think this might be.

Thanks

Here are some issues I've dealt with over the years...

Vibrations due to....


1. Flat spot on tire

2. Balancing of wheel/tire (normal stuff)

3. The wheel being bent

4. The wheel being out of round. It didn't look bent, but when you jacked up the front wheel, held a stationary object near the lip of the rim and spun the wheel, you could see that the entire wheel was warped.

5. Tire mounting bead being broken (there is a reinforced area on the tire where it mounts towards the lip of the rim. The reinforcing material (steel or whatever) had broken and there was an obvious bulge that you could see on the tire close to the edge of the rim. No balancing could take care of it.

6. Alignment problems

7. Bad/loose/worn tie rods.

8. Loose front bearings or worn bearings.


So... this could be your checklist of things to verify.

Be sure to check all the wheels. Sometimes it seems it's from a certain corner of the car, but it could be one of the other tires.

Good luck and let us know what you find out!
