Thumping/Bumping Noise under acceleration

[subysti]

Well I got my car back a couple of weeks ago from the shop after being there for 2 months. Today it started making a thumping noise under acceleration that sounds like the transmission is bouncing under the shift lever. dealership had to drop my engine twice for repairs and now I'm wondering if they didn't tighten something or forgot a bolt or two. There seems to be a lot of play in the rubber bushing that connects the driveshaft to the transmission, is this normal? I wouldn't think so. I've read here about driveshaft bearings needing replacement but is that the one connecting to the tranny or the rear diff? Should there be any movement at all with this rubber bushing?

Although I have heard the horror stories of others and their drive shaft issues, I haven't heard of them feeling or hearing a thumping or bumping noise while driving. From what I have heard the sound is more like a slight vibration and humming sound. Did you actually move the shaft around and see that there is allot of play in the bushing?

[subysti]

I was under the car and I could move the shaft around. Not a lot, but there seemed to be too much movement for a driveshaft. I could be wrong seeing that the rubber bushing is designed for a twisting force and not a up and down pushing movement.

OK, I have an 04',and I just checked mine and it moves around as well. Mine didn't move that much so that must be normal, plus, with the amount of tourque you have in that monster, that shaft would break into 20 pieces if you really got on the gas hard if it didn't have some play in it!

Have you noticed if the noise is louder when it shift through the gears or is it constant when you are accelerating?

[subysti]

Nothing to do with shifting, just thumps when accelerating kinda hard. If I'm real easy there is no noise. I can feel the thumping like something is bouncing up and down. Sounds like it right under the shifter. I'm hoping the idiots just didn't tighten something down real good. This is a new noise that I didn't here for the last couple of weeks since getting it back.

OH BOY, sounds like another trip to the stealership

I have an 04 and can't even move my drive shaft when I crawl under it. I can't twist it or move it up and down. So not sure what that means with the two of yours, but mine is pretty solid.

OK after a little more snooping, it seems to be the bushing above the support where there is a joint. Its moving around a lot there. Its a round doughnut bushing. Is this easy to replace and can I buy this somewhere else besides the dealership? Seems to be pretty easy to get to and to replace myself.

Is this at the transmission crossmember location? If so, I'm pretty sure you can get it through 1stVWparts.com.
