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.

Try to tie it to the road surface you're driving on. I've had cars that would start vibrating like they have a wheel out of balance over some road surfaces, but not all. If it's been a year since the "new" stuff was installed, it's not "new" anymore. If the car's been sitting a great deal, the tires could be slightly flatspotted. You might also have lost a wheel weight. It could be wheel bearings. You could have picked up a nail in one tire that's not yet causing a slow leak, but has thrown that tire out of balance.
Can you actually it feel it through the wheel, like the wheel wiggles in your hands, or does it feel more like the whole car is vibrating? Try swapping the wheels around on the car (put a front on the back and a back on the front), and see if that changes the vibration. If so, it's not the bearings, and more likely the tires. Keep swapping to see if you can isolate which tire it is, and examine that tire closely. |
