Hi,
That sounds like what's happening; it's coming from between the front seats (possibly just slightly behind them?) & definitely from the underneath of the car.
It's a rotating kind of a sound; with rythmic, repetitious "klunks" that increase and decrease with acceleration and deceleration.
Sometimes, when turning hard from a stop (as in pulling out of my driveway into traffic), it even makes a loud "POP" or two before the klunking begins.
I haven't had a chance to jack the car up & really get a good look at it yet but tomorrow I will.
Thanks for the info!
