My problem, 2000 4.7 Durango 4x4 during 30-38 mph front end starts to have low vibration/shaking. 50-60 mph the vibration is very aggressive and loud. When given throttle the vibration is stronger vs releasing the gas its less vibration, but still very noticeable. Only happens when driven. I can feel the vibration in the steering wheel and I can feel the vibration when my left foot is on the floor. The entire front console vibrates. The SUV still drives strong and quick powerful response with no lag at all.

Im thinking drive shaft or transfer case, but Im not sure.?! very frustrating!!

Things I have changed recently:
Spark plugs, spark plug coils, full synthetic oil changed every 3500 miles, wheel hub both sides, tie rods, upper lower ball joints, alignment performed, brand new tires, replace complete rear axle w/house and included rear differential.

Any help would be great. Dont want to end this great vehicle just yet.

 

Check your hub bearings again. Lift your truck and move the wheels. I had one crap out after replacing and never thought to check there since it was just replaced.

Check front drive line U-joints, check your tires, balance your tires and check inside the rims for mud or something throwing the balance out. Check your bushings.

 

I double checked everything. Its all fine. I noticed today, only when I give it gas it vibrates. If I release the gas and just let the car roll its more than half less the vibration. Im so lost!!!

 

I had this issue once before.. I can't remember what it was.

It was stupid simple/easy fix tho. ...but I paid $1,500 and just rebuilt the whole suspension (needed it anyway).

If I remember, I'll post back. I do remember it being simple/easy tho.

 

I hope you remember because I'm really puzzled.
