LandRover freelancer 3 door 2001 v6 auto. I have a problem with a knocking noise coming from underneath car when I am stopped in traffic with foot on brake. When I take it out of gear noise stops. It also seem to happen when I am on different surfaces which can be intermittent. Also from stop when I accelerate this knocking noise starts again till I get up to speed. It’s only done 74000 miles. Any help anyone can give me with this matter would be greatly appreciated
