off chance but what's the rear muffler like?? because.....

my car would make a clicking/knocking noise when cornering left, sort of sounded like a crap CJ you hear on front wheel drives. had the bearings checked, all ok, had the suspension checked, all ok.... turned out to be the rear muffler hitting the suspension. RMS ground off a corner of the muffler, neatened it up and now no noise!! hasn't hit or made a noise again
