Hey guys I'm new here I was just wondering if you could offer some help. My 98 ram 4x4 vibrates real bad anywhere from 0-30 and gets better at higher speeds. Ive already replaced my front axle u joints, axle shafts and wheel bearings + ball joints. It seems to be originating from the middle of the truck. The ujoints in the rear driveshaft and front shaft are good. The tranny was rebuilt roughly 10,000 miles ago and runs smooth and correctly. The vibration seems to get twice as bad in 4 wheel drive and 4 low slipped a few times and clunks. All of this seems to point to an internal problem within the transfer case. Any thoughts?

 

Do you feel it more thru the steering wheel, or the seat?

Welcome to DF!

 

Through the seat and the floor. I don't really feel it in the wheel at all.

Get your tires re-balanced. How are your shocks?

 

The tires have recently been balanced and rotated. Shocks are only a year old so I believe they are fine. I'm 90% sure it's a drive line/drive train issue

 

You've already discovered it: the transfer case. Time for a little R and R. It's really not hard.

I had a vibe that was completely mind boggling. Felt like the drivetrain too and would have bet my life on it. It ended up being tires. The treads were causing it.

 

That's

 

Alright. I bought a refurbished one online and I'm gonna install it and see what happens. I just thought it was strange how it only occurred a slower speeds

 

May be a crunchy bearing.... at higher speeds, it's still there, just not as easily felt.
