Would a damper sticking make a knocking noise/clunking? Top mount is bolted up tight no movement in this? But does sound top end of the strut, I just don't get it as the front is great not getting any knocking from here now just coming from back, I for one am very confused, I'm going to take it to another garage tomorrow for a second opinion as we might of over looked something simple or not so simple, what ever it is I just need to get it fixed as its peeing me off big time, first lowering spring causing me grief now a set of coil overs, I'm starting to opt for putting it back to standard and putting up with the range rover ride height :(
