This isnt related to new back window. Its always been there and does my head in when driving at low revs. Seen something on the forum about it before but cant find the post now. Seen various things on net about seat belt tensioners etc etc etc. This has got to be surely a common fault. Its doing my head in now so gotta get it sorted. Got rid of that trailing handbrake cable ticking on the prop shaft 2 yrs ago and put up with this vibration in the car at the back panel area since. I gotta sort it now. Had enough. Anyone point me to the post about this common fault or give some input on it I would really appreciate it. Thanks.
