New To The Website - Vibration Question

**scottthompson96** · 08-12-2020

Hi everybody I'm new to the website.

Trying to find solution to vibration issue with my 2012 3500 dually 4X4.

Here goes- while at idle in park or neutral when revved to 1300-1500 rpm can feel slight vibration.

No vibration at idle.

While driving when at same rpm it is amplified by 10X.

Very bad in 4th, 5th, and 6th gears.

I have unlocked the overdrive of the trans, installed 1 piece drive shaft, replaced trans and motor mounts.

Any ideas on what to look for?

The truck only has 126K miles on it.

Thanks in advance for any suggestions.

Not on my Dodge, but in a prior post my motor mount was bad, check that.

Welcome!

. Sounds like you have already replaced the most likely components and assuming the new drive shaft is balanced. Only thing I can come up with is possibly the harmonic balancer. Just a thought.
