Dropping my car in to the local specialist for its annual next week. Over the last year I have noticed a gradually loudening noise from the rear best described as mechanical/rotational rather than a more constant wheel bearing hum. Coasting in neutral sees noise unchanged. Noisiest at 35/40 just now, above that goes away/drowned out.
Suspicion is it is the rear differential. Anyone heard of this and if so can the diff be adjusted or rebuilt or is it a replacement job. 50k on the car but vigorous exiting of bends a frequent pleasure so may have contributed - alternatively has been roller mot'd which it is suggested elsewhere is not helpful.
Any insights in lieu of my mechanic diagnosing would be much appreciated.
Cheers
