2004.5 Ram 2500 quad cab short bed 4x4 auto. I have a vibration at 65-70. It is just enough to make the truck uncomfortable to drive. It's not always consistent. You can feel the vibration through the seats and see it in the rear view mirror. It has done this with 2 different sets of tires, one highway tread 265's and all terrain 285's. Could it be U-joints?

 

i think so.

 

Take it to a driveline place. My U joints felt tight but I got a healthy annoying vibration at 55 or so when on the throttle as soon as I let off...glass smooth. Cause was the rear U-joint...driveline guy said I was lucky to have made it back to town

 

Front drive line spinning slowly at highway speeds. The vibration is more than likely from that. Thousands of complaints of vibration on these trucks between 65 & 75mph. Mine did it too. Dealer will tell you its normal.

 

I seems to be only doing it under power. When I let off the throttle it goes away.

 

Regrease the splines/slip yoke on the driveshaft. It will probably help.

 

Umm. Front Drive line is spinning. VERY common problem. And yes, you notice it under throttle. Ask your dealer. His response will be 10 phone calls a week on this. Its normal.

 

Is there a way to stop it from spinning? or keep it from vibrating?

 

Not that I know of besides taking it off for the summer. There have litterally been thousands of complaints about this. Your dealer will say its normal. I wish that it wasn't. lol I have spoke with a lot of guys were denied the fact that it was the front d. line. They removed theirs and vibration went away. Try it out.

 

my 07 had the same thing at a higher speedit was a u joint. doesnt show up on the 06

 

Thats the response I got from 4 different stealerships here. It gets aggravating after awhile!!

 

I hear ya. I'm not tring to sound like them either. Its like Chrylser doesnt drive thier finished products. If they did, they would know that 8 out of 10 people with these trucks have this vibration. It drives me crazy. I take mine off.

 

That's Dodge I suppose. They gotta save $$$ somehow to give us those big rebates!
So how hard is it to remove the front driveshaft?

 

It is likely the drive shaft. Mine had a vibration at about 65 MPH. After I installed the free spin hubs the vibration is gone.

 

I had that same vibration. I let it get bad enough that I had to find it and removed the front driveshaft to get home. Dealer price was cheaper than having a driveline shop work on it. I bought the whole shaft and the problem never came back. The driveline shop told me the front u-joints are the same as they use on a Ford Ranger! I have a 2003 2500 4X4.
