I would suggest u check the CV joints on the drive axles for wear/excessive play.

This can be One of Two things, The Drive Shaft has a Bad spot and needs to be Replaced or Your Tires and Alignment need to be Checked out.

Vibrating at speeds of 50 miles per hour and higher, and a heavy vibrating sound. When stopped the front passenger tire is much hotter than the drivers side.


for your own safty and that of those who ride it, get it to some repair facility that has a lift-because it is only a 2008, it might be under warranty, and it might be as simple as a badly balanced tire (threw a weight?). A frozen or hanging caliper, bad wheel bearing, or a tire that is badly under inflated might also be the cause-just get it checked out.

I have 2003 Dodge Durango and when I accelerate above 40mph there is a vibration. When I remove foot from gas the vibration stops. Can coast at speeds with no vibration.


How many miles on your Durango? This could be a failing U joint on either driveshaft. Could also be a ties out of balance or going bad.

Since the vibration goes away when coasting, I am voting for a driveline issue.

It sounds like a bad U-joint to me. The only way to properly check u-joints is by removing the driveshaft. The joint should move freely, any binding will cause the vibration.

Front end vibration


It sounds as though your car has two seperate problems. The first problem with the vibration that goes away when you let off the gas pedal is caused by a bad INNER CV joint. It only vibrates when you are accelerating because that is when the joint is under stress. Your vehicle has two axles, each with an inner and an outer joint. My suggestion is to have a competent shop determine which is the bad side and replace the entire axle. The second vibration which occurs at any speed is most likely cause by either a bad tire, or a bent rim.
