"05 Hemi 4x4 - vibration during acceleration
Bought this truck 4 weeks ago with 71K miles on the clock. I replaced the EGR valve after receiving codes for it and also replaced the plugs with OEM copper core champions.
The truck vibrates quite a bit under acceleration. What systems or components should I begin to consider looking at to fix this? I have new Michelins that are balanced, front end aligned with new pads and rotors.
The truck accelerates nicely after replacing the plugs but the vibration is really noticeable. Should I look at engine mounts or U joints? Is there a harmonic balancer of some type on these vehicles? What about a timing belt. I know I need to read up more on this awesome vehicle but this is part of the research / lurning curve.
Please weigh in with advice and or experience.
Much appreciated,

I chocked the tires. While in neutral I tried to wiggle the drive shaft looking for signs of play. I couldn't find any tell tale signs of a worn U joint. When I tried to spin the shaft with my hands it moved maybe a 1/6" along its axis. I tried to push up an pull down on the shaft an saw no movement at the U Joints. Is there any other way to test the U Joints without taking them apart?

Is there any noise comming from the rear during acceleration? I have a 05 dodge ram w/ 4wd and while accelerating there was a squeaking sounding like it was comming towards the rear, along with a slight vibration. Switched out the U-Joints and vibration is gone along with the noise. See if there is any noticeable wear and tear on the u-joints...Rust etc
No noise from the rear during acceleration just a vibration under acceleration. There's plenty of rust on the existing U Joints, they're probably the factory originals. I'd be happier going into changing these parts out if I was able to be sure there were some signs of wear.
I had a bad vibration on my 03. checked the drive shaft no slack. put it on ramps to weld in my new exhaust happened to rest on the drive shaft and bam, found a broken cap at the transfer case and the rear differential. changed them out and obviously it went away.
