I have a 2005 Dodge Ram with the 4.7L in it. Recently i was driving around town and i noticed a vibration in the truck around 45-50mph. On the way home from college yesterday, i felt the same vibration, even more noticeable, at around 60-70 mph. Has anyone had this problem and if so what could it be? The truck isn't lifted or anything and has the OEM 20's on it. Thanks for your help!

 

Vibration in the steering wheel or seat( not a joke)

 

can you tell where the vibration is coming from? under the cab, at one of the wheels, etc. Does the vibration change frequency as speed changes?

Seems to me like if its dependant on speed its definently something that rotates and is out of balance (wheel, driveshaft, etc.)

Start off making sure all your lugs are torqued.

 

Yeah ive checked all the lugs and they're torqued. I can feel the vibration in the steering wheel and also i can feel it in the seat. Its hard to pin point exactly where its coming from

 

Check the for the obvious bad tire, bent wheel, u joints, and make sure you haven't bent the drive shaft some how. A blown shock will allow the wheel to bounce. These are the the first steps i would take.

Have you lowered or lifted the truck ?

 

Nope the trucks perfectly stock and its a two wheel drive! I need new tires and im getting them in a few days but the vibration is way too strong for me to think its coming from the tires. Ill check the drive shaft and u joints and get back with you in a few

 

Tires that have never been balanced other than the original install can make it feel like your driving on a dirt road.
