During my last drive from BC to Alberta, with rather heavy load in the trunk,I started to hear a noise when going over some less smooth highway.It seemed ,when listening from the driver 's seat,like emanating from the left rear safety belt harness inside the wall.When sitting in rear it sounded more from the centre of back.The noise at the begining was like a loose nuts or similar,later it developed in more like a bumping of the body against something when hitting some rough on highway.
During the trip( 1 900 km) I asked two garages to identify the problem,nothing has been found.
When returning home,I asked my standard garage repair place to investigate.They did not find nothing serious with a definite answer to this problem.
Did somebody had a similar case?From my own thinking it looked like a shock absorber problem,but garages did not find it like that.
