New tires, new wheels, new shocks. 55 and up shake/vibration in the steering wheel. But here's the kicker. It come & goes. I can go for maybe a mile or even 2 or 3 and everythings fine then for some reason it starts back up again for maybe a mile or so then quits. Tried diff. speeds and seems like it makes a diff. but can't tell for sure.

Bent wheels will do that to you. My other 914 had a horrible shake, and it would come and go as you said. When I had the tires off I brought the wheels to a tire shop and had them check for roundness. Basically they stuck the raw wheel on a balance machine and used a white marker on the wheel. Wheels with a mark on the full circumference were straight, marks on part of the wheel only - were bent.
That will cost you about 50-75 bucks to check it that way. I am sure you had your wheels/tires balanced when installed - check to see how many weights are on each wheel. Wheels with more than a 1/4 ounce on them have a problem of some sort. You can have the tires moved or spun on the wheel to see if that corrects it, or that is an indication that your wheel is bent. Since you only have a couple of hundered miles on the tires I would pull them all off, put the wheels with the smallest amount of weights on the front. |
