everything seems ok, cannot move any ball joints, but will maybe jack it up again and have a look, thanks for all the help

Did the knocking occur when going in a straight line, or when on a tight curve? I don't know whether the S80/New V70 are the same but the old S/V70s used to suffer from a knock at full lock on rough ground if the lock stops weren't lubricated. At full lock, a nylon pad on the suspension moves up and down against the lock stop and makes an awful noise. A smear of grease on the pads fixes it.

on rough ground there is no knock, but slightly bumpy roads say a small pothole, it knocks, but not when turning ect. seems only on the nearside front. maybe it is a worn joint that does not show up when i jack the car up.

I had this same problem on my 2002. It got so bad my wife wouldn't drive it. It turned out to be the plastic skid plate (actually a protector for the oil pan and filter) had 2 bolts missing .It must have just been flexing.

hi

it seems just from n/s front, on normal roads, no knock, but any small bumps and it starts, not very loud, i did notice some play on the top suspension mount, under the bonnet (hood) but maybe that was just some bearing play. as the nut was very tight.

I had same problem with my 2007 s80 150,000 miles, replaced struts and upper mounts , problem is gone, I don't think it really needed the mounts but I wanted to make sure so replaced them. The struts were shot. $600.00 later rides and sounds like new .
