no mention of speed related vibration issues.

My car has 44000 miles on it. I am riding on KW V3 coilovers and the front height is about 25.5 inches ground to fender. Some of my symptoms include the following:



1 Clicking upon hard acceleration-This happened a few times last summer but not recently. This would indicate a bad CV joint?

2 a very light hum at cruising speeds on certain roads but not often- this could indicate a bad wheel bearing but it could also be from my GY F1 gs d3 tires. I don't think this is related to my high speed shaking issue.

3 When i turn the wheel full left or full right while backing out of a spot on an incline I hear some thunking sound which would also indicate a bad CV.

The shaking is not engine speed related but vehicle speed. Over 80 mph and mostly in 5th gear. The steering wheel feels loose and the front end shakes.

I have moved the rear wheels to the front and the problem still persists. So the chances of an unbalanced wheels is unlikely.

Can a bad CV damage an axel which in turn would cause this vibration? If I remeber correctly, my cv boots looked ok. The car only has 44000 on it??

Also I have NOT gotten an alignment since my coilover install last december. Could this be related?

I am over my 4 year warranty period but am under 50000 miles. What should I be prepared for when I get the call from the service dept. tomorrow?

I appreciate any insight you all may have...

it could be something simple like a wheel weight fell off causing you to be out of balance

I think their is a more serious underlying problem

Realign, maybe the tires need to be rebalanced.

quickhuh

you can go to a higher end tire shop and the can road force test it to check that stuff

B56

No I did not

Why not??? Go get an alignment.

You should have one after every suspension upgrade. Get one and report back, i bet the problem will be gone

they've already worn incorrectly.
