After reversing out of the driveway, and braking to a stop, when I depart (forward) there's an occasional loud "thrum" - it sounds as if there's been some spring tension taken up somewhere in the underpinning which gets released when the vehicle moves forward. As I say, it's not constant - possibly due to the amount of torque exerted during braking - and basically impossible to duplicate intentionally. I should mention that the reverse leg ends with a 1/2 turn right or left as dictated by the daily plan. The direction of turn doesn't seem to have any effect on the production of the noise. I had my dealer look into it about a year ago, and they weren't able to come up with anything either (possibly looking more closely at the front suspension - I think it sounds more like the rear...). The vehicle: '98 V70, 200K KM, purchased March '06 at 170K KM, last major work done was replacement of rear disks and rotors about two years ago, nothing else of note.
Also: where's a safe place to set jack stands at the rear of this vehicle for ease in giving the underneath a good going over? Thanks everyone.
