I have noticed that I am getting a vibration if my tahoe is above 45 when I am decelerating, I cannot figure out the problem. Any help is greatly appreciated,
Thanks

 

could be many many things
1.hub bearings
2.rotors
3.idler arm
4.lower ball joints
5.half shaft (front)

I say take it to a mechanic and have them check it out

 

Vibration when "decelerating" with foot ON or OFF brakes?

What year and miles on vehicle and also what size tires?

 

Foot is off the brakes, it is a 2001, with 76,000 miles. With standard size tires.

 

You're not driving in 4X4 I assume?

Does the vibration shake the truck (can all occupants feel it), or is it felt primarily thru the steering wheel?

The frist thing that I would do (starting cheap) is have the tires inspected and rebalanced, if that doesn't cure the problem then have the aligment checked and adjusted as well, most often these types of concerns are tire related.

If none of these things solve the problem you may want to start looking into the drive system checking u-joints, drive shafts and so on.

 

mine did this when the u-joints on the rear shaft wore out... $10 at AA...

 

ok just read other tips very helpful or motivating? !! lol no vib. thru steering wheel. others can feel it ...seeems more pronounced while making gradual turns l. or r.
