I am getting a slight vibration at 80 to 90 mph, then it subsides if I speed up or slow down. I noticed it last week and I thought it was the tires. They were the original set. So, I just put on a new set of PS2's today. I had them balanced on the Hunter GSP9700, but I am still feeling a vibration.

The tech told me that all of the rims were straight, no bends. Just had the alignment done and the car tracks perfect. Brakes and rotors are perfect. It's the strangest thing. Any suggestions? Does anybody know a shop in the Annapolis area that I can take her to and have them checked again? Maybe it was the tech? I'm out of ideas.

 

might be your suspension. they may need to tighten up various bars, etc. happened to me.

 

what's your tire pressure?

 

Look at the rotors for hotspots

 

did the tech check the rims on the machine? does ur steering wheel shake at 80 mph or do just feel some sort of vibration?

 

I'd guess it's a slightly out of round rim.

 

I feel the shake on the steering wheel and slightly in the seat. Rotors are all good, tire pressure is 32 front, 39 rear on brand spanking new rubber. I did hear a slight noise under the front end yesterday, like something was slightly loose, sway bar maybe? I'm going to check her out today. If it's a rim can it be repaired or should I start looking for a replacement?

 

what road force reading did you if they used hunter machine?? that will make biggest diffrence ..

 

Ride match balancing should do the trick
