Front vibration through steering - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I have the same problem. I have vibration at 75 MPH plus. I'm going to get the wheels balanced and I'll let you know how it turns out.

Had my wheels balanced this morning and went for a test drive. The vibration problem seems to be fixed, at least for now.

I've replaced everything up front now, with the exception of the steering rack. Given that I can feel a bit of "slop" just off center in the steering, I am unfortunately concluding this problem to lie within the rack itself.

Does your car shake, or just the steering wheel?
I'm sorry hear about this snipe hunt of a problem you're having. Is there anyway it could be one of the rear wheels?

I find it odd that the steering rack would vibrate only at certain speeds. Then again, I'm hardly a mechanic.

Anyway, I hope that solves your problem.

Rears have been balanced as well. The rears are due for new meats, so I'm thinking I may replace those and double check all the alignment #s before ordering and swapping the rack out.

My car had some vibration when it was time to replace there rears, noticeable at various speeds. Definitely a smart move to take care of that first. It fixed my shakes.

I did a search for "brake rubbing" and found this:

Not sure this will help but I had a really bad vibration on the front right wheel and could not find the source. speed and slip angle were influencing the degree to which it could be felt. After a lot of searching, including the bearings we eventually found the front engine mount to be the culprit! replaced it and all vibrations were gone! In your case though my feeling goes towards the bearings...
Let us know when you pinpoint the cause!
