I'm posting this in brakes section, although the issue may well be in hub, drive shaft or diff area.
A noise is emanating from the rear offside which is a scraping sound at walking pace but becomes a squeaking at normal road speed. The noise has a frequency which increases with road speed. The noise disappears when lifting off the throttle or braking. It also disappears after a few miles of driving, presumably when the offending component has warmed up.
Jacking up the rear wheels and putting in drive to spin them does not generate the noise. Turning the hub by hand doesn't produce the noise but there is a slight soft scraping sound which I think is caused by the brake pads rubbing against the disc when turned. There's no noticeable play in the hub bearing.
I suspect the rear disc brake is the culprit. But before I start stripping down has anyone got any thoughts on what this could be?
Thanks in advance
Peter
