Vibration

[shenysz71]

I recently experienced a vibration that can be felt in the throttle pedal and in the seat when driving around 40-50 mph. My 2018 2500hd has 42,000 miles on it. I just had new tires put on it and was fine no vibration then about 1500 miles later I noticed the vibration took it back had the tires re balanced and same thing. The Chevy dealer said it was a bent rim on the left rear, I rotated the wheels and even had them rebalanced at a tire shop, they said the rim is not bent but still have the vibration. I am leaning towards u joints seems to me it is in the drive line. Seems odd they are bad at just 41,000 miles. Any suggestions would be greatly appreciated. Thank you

Replace your problem tire with the spare. See if the problem goes away. If it does, replace the bouncing tire.

You sure it's not the converter clutch?

Did that, nothing changed.

As Mike said, or you couldve took a hit on the driveshaft that unbalanced it or a ujoint failed. Gotta check everything.....

Tires are funny/frustrating. Sometimes, not always, at 75 my tires seem to vibrate, at 90 they don't - smooth as glass all the time. I don't understand why this would be.
