There is a deep bassy droning noise that gets worse (louder) with road speed. I've played about with different speeds and throttle openings and it's defo road speed related. It's the 1.9 Turbo diesel. Any ideas? Back to top SambaFi Running In My Car: Nissan Note Joined: 24 Apr 2008 Posts: 258 Posted: Sun Oct 25, 2009 9:41 pm    Post subject: Possibly the differential.

I was promised a call back with quotes for the work needed (new tyres and front brakes aswell) but still waiting... Also car was fine before the service!?

Definitely. The only real fix is new wheel bearings - they're not very expensive though (normally).

Get them changed all the same.  They are not expensive. _________________ Mark Back to top DaveGibson Supercharged My Car: Lexus IS250 SE-I Auto.

The only upside is the exhaust has been an advisory the last two years and its outer shell came off a few weeks back, so I can get a stainless custom made _________________ Small car, big heart.

My Y-plate Megane had a bearing go at just over 18 months old. Don't know how representative of Renault that is, plus it had done over 40,000 hard miles by then, but all the same... _________________ Just keepin' on keeping on.

It can't just be the suspension that gets damaged when you hit a pothole hard enough.

It can't just be the suspension that gets damaged when you hit a pothole hard enough. Crashing into potholes is something it does very well! It's done 32k and does need new fronts so could be both? Presumably things like wheel bearings aren't covered by warranties? Back to top DaveGibson Supercharged My Car: Lexus IS250 SE-I Auto.

It can't just be the suspension that gets damaged when you hit a pothole hard enough. So long as there is minimal wear in the bearing, any impact through the wheel should have little effect. Any damage would be caused by the sudden impact of the bearing components on one another which should only happen if there is any looseness within the bearing. It follows, of course, that once any wear has started, rough roads would make it get worse more quickly. Back to top Jasper Turbocharged My Car: Is sitting just right.

Maybe but it's not a feature I've noticed before on other cars. Maybe it was them spinning up all the time. They really had piss poor grip in all conditions.
