I got the same clunking after installing Meyle HD bushing. After 2 days triple checking everything I did; torque everything to spec over again; and checking forums to identify what did I do wrong?
The problem boils down to Meyle bushing design is not same as the OEM. The Meyle bushing outer metal cylinder where the control arm is inserted, the edges are not slightly bent out as the OEM. The control arm and the metal cylinder touch every time I hit a bump. I will replace with either a polyurethane version or OEM (not sure yet). BTW, I did a temporary fix to this by cutting pieces of the old bushing rubber and inserted in the open gaps between the metal cylinder and control arm (it's holding really good so far).
