Resolved Question:

I have 330i M Sport E90 2005 38,000 miles done.....there is a kind of droning noise when driving which increases at higher speed, usually above 30 mph. A local mechanic thinks the rear wheel bearings are going. What would be your opinion?

does the noise change when you turn?

 

what part of the car does the noise come from?

Well as I'm slowing down to turn it's not so noticeable, it seems to get louder when I go above 40 mph although performance seems normal. Noise feels like coming from wheels even sounds like something is obstructing the tyres but I checked and there's nothing.

I would suspect it to be tire wear, wheel bearings, or the transafer case/output shafts. If the car is raised for inspection and run in the air, you should be able to have it narrowed down further

So probably is wheel bearings as the mechanic was able to inspect car on ramp. He's quoting me £700 to replace both rear wheel bearings. Does this sound too much or is going to be time consuming to do so high labour cost? are the parts expensive?
