I have a 2000 durango that vibrates bad at about 55 mph and up put new tires on it to make sure it wasnt the tread any feedback would be appreciated its 4wd 4.7 engine.

 

Need further info. Does it happen when under power or coasting? Can you feel it in the steering wheel? Is the vibration coming from the front or rear? As you can see, having as much info is better for us to help in the diagnosis.

 

Also does the vibration increase or decrease with speed? Can you make it go away after a certain speed?

 

The vibration seems to be coming from the back but the whole truck vibrates its ok as long as u dont hit highway speed and seems to lighten up around 70

 

Check your rear u-joint for play. Possible u-joint going out.

 

put it in neutral and try shaking the driveshaft towards the rear/u-joint...if it moves replace the u-joint.

My truck was doing same thing and the u-joint was bad..My truck also did it above 90 and i found out driveshaft was bad....

 

i replaced the u-joints in the rear still bad vibration

 

You just might have an out of balance or bad tire. I know they are brand new but a defective one I would not rule out. Maybe a slight bent rim but you should feel that at lower speeds too.

 

Yep!


Just had one last week and got a brand new one. Only had 2k miles on it!

 

They just don't make tires like they did many moons ago do they hydra. Seems to me that they are getting cheaply made at a higher price.
