Have been having an intermittent knocking from the rear of my car for a while.
The knock is coming from beneath the rear offside passenger seat, where the base meets the seat back.
The knock occurs only when I am changing from first to second, and from second to third gear. Happens when the forward motion
of the car slows when you depress the clutch to change gear. When I change gear it sounds as if something is knocking against the underneath of the car.
I have looked underneath the car but nothing obvious. Just had the car up on the ramp at my local garage and they reckon the fuel tank straps may need replacing
as you can push the fuel tank up approx. 1/2 an inch. They have checked suspension and prop shaft but nothing obvious.
Does anyone know if you should be able to push the fuel tank up, or should the tank not move when you push it?
Don't want to fork out on new straps to find out they were ok.
Any other suggestions regarding this knocking noise would be appreciated as it is really starting to bug me!
