Im trying to find out the cause of a knocking on the front left of my rev3. It knocks over bumps even going over white lines like the speed camera lines on the road! On closer inspection of the top mounts left and fight have different lookin top mounts on the front. On the left the wing has been changed at some point for a uk wing so i am guessing it has had a knock. Also the topmount on the left looking from the top has the nut in the middle and one raised metal ring around it but on the right it has two metal rings around it. Also the nut in the middle sits lower in the topmount on the right then the left. Does anyone have a picture of what a rev3 topmount should look like they could put up for me? Maby someone chenged them when it had a knock but put a rev1/2 on the left? Thanks
