ive had this chronic problem of a clonking noise in my 230's rear end, it would happen when starting from a stop, accelerating quickly while in 2nd gear, and engaging gear. i replaced the upper differnital mount and it stopped the noise when engaging gears but it still makes the noise while accelerating & starting off. i noticed also i can get it to make the noise if i move the selector from R to 4 or 4 to R, but only after i have moved the car a little (doesnt happen when sitting still and going from 4 to R etc...)
any suggestions?help would be greatly appreciated! my thought was maybe the locating strut bushing, or maybe the bushings in the trailing arms :/
