I have 1995 dodge ram 1500 sport 4x4 it has the 5.9 in it with 97xxx mile on it . I also have 37 12.5 r16.5 on it. I recently purchased it but it has a viberation that comes as you are going down the road but i can let off the gas and give gas back and it quits. Any ideas what can cause this?

 

Check your u-joints and see if there bad. How many miles on the shocks ?. Have you had the tires balanced ?. Just throwing out some ideas.

 

I dont know about the age of the shocks,they look like they are not to old. And it doesnt feel like a tire viberation im going to check the ujoints this afternoon after work. I jave noticed that the previous owner did put to much transmission fluid in it so if you drive a extened time now it leaks out of the vent but i have bought everything to change it this weekend.

 

With 37s on it, I'm guessing it has a lift kit. What do the u-joint angles look like? The front and rear joint should have the same angle as each other. If the front one has a lot of angle, but the rear is fairly straight, that could be the problem.
