Repeatable Banging or cluncking on acceleration only

2005 V6 3.2 103,000

I am putting this up for all to read, in the hopes the symptoms will resonate with someone. This only happens when accelerating briskly from a stop on hard to pass someone. It is 3-5 bangs or cluncks, seems like under the passenger seat. They are not rhythmic more like bang (pause), bang bang (pause), bang, (pause), bang... It does not do it when accelerating smoothly or at any other time. It does not seem to effect the acceleration, no slipping or loss of power noticed. It really feels like something is banging on the floor. The mechanic changed the drive shaft and said the bearing was shot, but the problem is still there. Now he is saying possible front driveshaft bad, or transfercase issue... before he starts throwing parts at this, has anyone got more ideas???

If the centre bearing isn't correctly aligned . . .

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]

Must be the season. I'm having the same symptom as finmad.
I pull the plate that holds the center bearing that the driveshaft runs in. I am assume this is the centre bearing noobytoogy is referring to.
The bear and its support seems okay. Rubber is not shot and the bear rotates freely for the 45 or so degrees that I can rotate it while the driveshaft is still in the Touareg.
Not sure what to check to see if the bearing is properly aligned.

Motor mounts seem good. No noticeable vibration when revving the engine.

Any suggestions on testing the rubber bushing that the center transfer case mount sits in?
It looks okay but short of taking the transfer case out I'm looking for a suggestion on how much force should be needed to move the transfer case.

TIA
Steve

I have the same problem, it is worse when the vehicle is fully loaded and going up hill. My local mechanic checked it all over and could only find some play in the front propshaft mounting. It sounds to me like a broken engine or gearbox mount causing the transmission to bang on the body when it is under load.

I am taking it back tomorrow with the car fully loaded.

andapp,
Did you find out if it was a broken engine or gearbox mount causing the problem?

I have been getting a vibration under load at low revs (1,300 to 1,800 rpm). I'm thinking it is an engine mount.

Mine is getting worse. I can now get it to go thunk, thunk, thunk at anytime by accelerating hard. It continues until I let off the throttle. Now can feel it in the floor under the driver's side. Passengers claim the noise is coming from any where from under where the radio is to under the back seat. It never feels like it is coming from below the center console. Anybody else have any more info? TIA.

On my 05 V8 with similar miles, I had to abandon ship and have it flatbedded home.

Banging like the hammers of hell...never heard anything like it. I was convinced it was the driveshaft.

Towed home...Got a call from the dealer...one of the wheels had thrown off its weights...no charge!

Freaky.

I also replaced the front differential, that noise was more of a whine/grind...nothing like the pounding described above.
