When you say not a typical noise, how does it sound?

Is there such thing as a dry bearing anymore, it sounds a bit like that. A droning noise, a bit like something rubbing against the wheel.

Is it true the tyre can make a noise like this?

Post by: Osprey on 08 October 2011, 23:49:50: Also, get somebody with good hearing to sit rear right with the left seats folded down and report on where the sound comes from. (Take a boke Poke!) Then drive straight and around left and right bends. Bearing noise usually changes as the relevant wheel is loaded and unloaded on bends.

Jack that corner up and check for play 6/12 o'clock and 3/9 o'clock. Rotate wheel 1/4 and 1/2 turn and repeat.

Check for diff fluid leaks while you're under there.

Post by: gareth. on 09 October 2011, 19:47:39: I jacked the wheels up, but there is no play.

I now think it's the diff, (I had a feeling anyhow but I didn't want it to be). Is it a big problem, have I done much damage do you think?

I went under the car looking for the holes for my towbar and I noticed the bottom of the diff was wet (looked like oil) and the exhaust underneath had been dripped on. :(

Post by: I_want_an_Omega on 09 October 2011, 20:24:11: you could eliminate tyres by doing a front/rear swap.

I had this problem - turned out to be the rear tyres :-\

Post by: kcl on 10 October 2011, 10:32:12: I've had once a very noisy rear wheel bearing and there was no play in it. But the internals were quite rusty, water had got inside the bearing and it's assumed that the noise was due that... Af course some internal damage was caused by the water but still, there was no play in any direction.
