help diagnose: vibration runble + steering feedback

Amleto · 5 Jun 2009 at 08:08

hi,
this recently started on my 05 st220. I have been over a couple of heavy pot holes

At motorway speeds (starts about 70, gets worse towards 90) I get a vibration+rumble through the car - you can feel it in the seats(!) if you go fast enough. There is also more feedback/vibration through the steering as you go faster.

Am I just looking at balancing or could it be something worse?

Best case the wheels need balancing, worst case you've buckled them when you hit the potholes

hmm. I have a sinking feeling

IIRC, the vibration from unbalanced wheels can tend to fade the faster you go. It could be any number of things like bad alignment, worn bushes, warped disks etc.

Depending on where you live and the competance of your local garage I'd get your wheels checked for balance and if it's still no good get the alignment checked

Could also be a wheel bearing that needs replacing. Does the car pull to one side at all?

I don't think it wants damp seats.

car doesnt pull. I just put new pads on the front for my MoT that was in march - I dont think the discs are a problem.

will get a balancing/alignement check over the weekend.

thanks for help
