Hey guys my 06 s2k is only vibrating/rumbling for a secound or 2 only when decreasing speed at around 20 mph. It dont matter if the car is in gear or neutral. It does not vibrate at any other speed. When accelerating if i step on it a little i do feel nothing but if i go slowly up speed i do but not as noticeable as when dropping speed. The car has 93k. Just wondering how would you guys approach the problem to fix it. Thanks for the help and advise

 

Can you post a recording of the sound so we can hear it?

I seem to recall something about an ABS noise that only happens at a certain speed, but I thought it was more like 12 mph. Something about abs module recalibrating itself or something. Search for that issue, see if tue symptoms are the same as yours.

 

check your calipers for sticking...(one wheel will be much hotter after drive). I have been chasing similar vibration (at slower speeds). And found my rear caliper stays on after it heats up a bit...also there was some mild noise more like wheel bearing going bad. (i guess you can call it rumble)

 

First thing I would check is tire balance. If you pitch a balance weight the car can hit a resonance frequency at certain speeds.

That's my thought. Or one of the tires ate a nail.

 

ill try and see if is audible feom a phone recording thx

 

oh man i will check the calipers for sure because a while back they where sticking to the point that i had to take them off and put some grease on them. I let u know

 

ill try to switch tires with my wife and see if it keeps vibrating. If it does not then ill know is tire related. I keep you guys posted. Thx

 

So i decided to try my wife's ms3 tires on my s2k and sure enough no vibration at all
