So thank you Bustedback for your information. Greatly appreciated. My 2006 Jeep bounces while I am driving as if it has a flat tire. At first it was on the interstate only. It happens on rural roads and once or twice at 30 m.p.h. I had all of the tire pressure sensors replaced. It has 132,000 miles. Purrs like a kitten. Excellent gas mileage. But this problem just started up in the last year. Does it have anything to do with the 4x4? I did get all new tires last year. I have put 2300 miles on them. Wouldn't think that would be the problem.

 

shocks?

 

it could be...
tires (out of balance or broken sidewall wires.)
shocks
wheel bearing
lugnuts
etc...

lift the tires off the ground and do a thorough shakedown.

goodluck

 

Thank you for the info. I took it back to where I purchased the tires. They said
they checked it out. Could find nothing wrong. I will take it to a different garage. Thank you.
