Iirc the fronts are pretty much fool proof when fitting because of were they sit but rears can be moved.Its 5 years since I changed all the belts in my Sapp but I had an issue with the rears.
Slacken off the bolt that holds the seat bealt assy to the car and run the belt in and out see if that does anything.It may of been the top mount I had a problem with I think as there is a plastic washer there and it was binding a little bit and not returning to where it should of been making the belt return slowly.
Does this make sense to you lol.
I only have one bolt holding mine, at the bottom where it connects to body work!
Tried it with it loose but still the same!
Was going to try and get all probs done in time they give for free retest but might hold off now and sorn her off road as got few things in pipeline for her!
But as you know if you can't drive them it makes you want to even more lol
Do fancy a little Xmas joy ride while off work
So do I rush about spending unesesary money now or just wait till I've finished all my planned work?
