Ok so I've just had my clutch done, and it's been like driving a new car. Only when took car out just now to nip to the shop, I'm hearing a pretty loud rumbling coming from the rear of the car. Only really noticable at around 40mph, noise remains when clutch is dipped etc. It's not noticable below about 35mph. Any ideas please people? Hoping it's not the diff etc.

 

wheel bearing/diff

 

Aye was thinking the same. I'll jack her up the day and check the wheel bearing
