Hello I have a vibration @ 30-70 MPH I thought it was possibly the cab sitting on the pumpkin or something of that nature,..but i just changed the rear spring to a composite and its still there. Its not indicative to something that is detrimental to the vehicle since I have driven it about 2000 miles with no change in the sound or perfomance. I had the pumpkin checked whenI had the oil changed ,..no problems with the look of the oil. it seems like it could be bearings but I waould assume that they would get worse?

Also I Have a lot of play in my shifter(auto about 1.5") and steering wheel(left to right about 2.0") is there easy fixes for these malities?

Any ideas??

 

Check to see if you have lost any wheel balancing weights.
Hows your tire wear?

 

could be the tire weights like Starship said or could be drive shaft weights or u joints. or even a bad tire for that matter. I just put new tires on one of my old cars and the left front was seperated and caused a horrible vibration when not accelorating. made short work of the wheel bearings. wishing you luck.

 

Also check steering componants, tie rod ends, etc.

 

Hey thanks for the replies,..it could be the u-joints or weights,..the tires look pretty new,.but it does'nt shake the steering wheel like tires that need balancing either.

 

Ya, check your u-joints. Also see ifthe yokes on the trany and diff have any play.
