Hey I have a 97 Blazer 4dr 4x4 and ive noticed recently a vibration in the pedal and in the steering wheel, not horrible but noticeable. Could this be a motor mount or what other possiblities are there before I go about replacing the mounts? She has 181k haha so I wouldnt be suprised.

 

Bumping this up although its an old thread. I got the same problem and I'm looking for an solution.

 

There is no where near enough information in either of your posts to form any kind of hypothesis as to why you are experiencing what you are experiencing.

When does this happen? What speed? What throttle position? What gear? The list goes on. There needs to be a LOT of specifics to diagnose a problem through a computer screen. Please take the time to fully detail your situation if you hope to get any meaningful responses.

 

The last two day I have noticed some vibration through the floorboard, brake pedal and gas pedal. Sometimes at the steering wheel.

It gets more noticeable when I let my foot of the gas pedal, and/or apply some brake.

Sure hoping for some help

 

Had a look at the U joints and wheel bearings today, could not find anything loos.
What about a warped brake disc, could this give these symptoms?
