Problem: Banging from the drivertrain when pulling under load eg accelerating in 4th at 50mph, but seemed to be getting worse!
Situation: Car has had the mudguard fitted in 2019, and I added Phil's bevel box mount in 2020. Phil had kindly centred the rear drive belt on the rear sprocket when we did the Centa upgrade in May21. Car is now 7K miles on its original tyres...
Evidence: Looks like the side of the mudguard mount was being worn away... by the drive belt!
Theory: As the rear tyre has worn*, the gap to the cut out in the rear mudguard mount for the belt has reduced. At rest there is 3mm or so gap, but clearly under load there is some belt flapping from the part of the belt opposite that under load (maybe its stretching?).
Solution: took out the mudguard**, and the mudguard mount, and dremeled away some of the allow material, added some hammerite to cover it, and presto, no banging any more (from the rear anyway)!

Something else to check for.
