lately I have been experiancing a creaking sound that seems to come from the rear on the left hand side when i make a right hand turn. the last time i heard this noise it was being made by my exaust- the rubber hanger was broken on it - i fixed that and all was good until last week. i jacked up my rear yesterday and checked out some key things; all exaust hangers are in place, as is the entire system stable and secure. my springs and shocks all seem to be in good condition and have normal wear. i have read that wheel bearings might be the cause of this noise as i have read in some other threads ealier. would there be any visual indications of the bearings needing replacement? any other ideas?
