2000 volvo v70 awd turbo se making 'thud'

I have a 2000 volvo v70 awd with 137K miles. It has just begun making a "thud" sound when going up or down a slight grade upon takeoff. The noise is in the area between the front and back seats under the car. The transmission is shifting smoothly through all gears. I only hear the thud at very low speeds. Any one have any similar experience or idea what this might be? We do most of our own mechanical work, but this is something we haven't been able to figure out! Thanks.

I haven't experienced this, but I have some thoughts. There could be some "play" at the input of one of the driveshafts or differentials. It could also be a suspension noise. Maybe a loose end link or shock mount that moves when weight is transferred? Maybe something rolling around on the floor?

Thanks for your response. It does sound like something rolling around on the floor; we removed everything loose from the car, and were able to replicate the sound by rolling slowly on our paved driveway. We still get the noise even with the engine off, and the car rolling in neutral (down a slight grade). We put the car up on jack stands to do a visual inspection.There is nothing loose and no play anywhere on the drive shaft. Sounds crazy, but my husband looked under the car with his head hanging down as I drove slowly to see if he could see anything, and we again heard the noise under the center of the car, seems to be in the area just in front of the rear wheel wells, but in the center. Again, we hear this noise only at very low speeds, forward and backward both. Incidentally, it is an automatic transmission.

Hi, it could be the differential = have you check the fluids? Or the exhaust rubbing against the upper body? That's where I would look. Failing that put the car on a hoist and check the drive shaft, uni joint and check for side movement of the rear wheels.
Good luck.
p.s. My 2001 V70XC has just turned 180000kms and only issue with it now is the core plug(like the common distributor but our series has one for each spark plug and they are $200 each = DOH!!)

My V70 is 2002, but problems almost identical, plus right front axle, door locks go up and down as they please, right turn signal stop cooperating, cigarette outlets don't work (yes, I did check fuse), car is shaking at 60 miles per hour (nobody can find problem) and finaly I can't get more then 15000 to18000 miles on top line tires, tire shop keep telling me it is VOLVO vag, they known for this problem????? I had 2 Suburbans before, I drove them in to the ground, 200000 miles each, never a problem, tires were used for minimum of 60000miles, and that car is much heavier... Please, can anybody tell me any thing????

My problem was diagnosed today. My indie mechanic says I have a bad rear torque tube bushing. Cost $100 inc part. Imagine what the dealer 'might' have said my problem was. Bad differential? The sky's the limit. Whew was I relieved.(Same mech welded a leaking tube on the tranny of my 1994 940 yesterday, $150 inc a fluid/filter change) Did you get an alignment at a good shop, check the wheel balance? Bent rim? Bad front end parts? Sounds like the tire problem and shaking could be related. Are the tires wearing unevenly? Not sure about the electrical problems, those are tricky. Good luck.

I know I'm late in responding, but IMO that's a whole of stuff to be going wrong on an '03 w/35000 miles. I can't believe that AZ heat is causing it all, like: fuel pump assembly for $1000. And transmission pan seal is leaking and will be $900 to replace????
If you told me it was a Land Rover, or old M-B or Audi, I'd understand. But I'm thinking your Lemon thesis may be correct--personally I'd sell it before you go broke......

Think you are right - if consumers reports mean anything , the 2002 and 2003 V70 are solid black for suspension related issues among others . Its pretty much a Toyota Venza , or Highlander . Gut tells me to buy American like a Ford but they are essentially the people who tell me to go to hell. GM has nothing I like . OK maybe a rear wheel drive Cadillac CTS wagon but the stylists have screwed up the rear opening height and reliability is not reported that hot+ they are pretty dear. But it looks like I am going to have to order to get anything close to what I want - hope the Volvo will last 10 -12 weeks. Today the ignition switch started binding. Cripes -
