How can you tell if a rear bearing is noisy then? With my duff hearing I often can't tell where a noise is coming from.
Not easy, the noise sort of comes vaguely from the back seat & boot area when it's getting bad, the problem is that it transmits around the whole of the tub. It's not even easy to decide which side it is sometimes.
If I suspect a rear bearing, quickest way I have found to diagnose is as follows. Chock front wheels, release handbrake, jack the back end up and remove the wheels. Pop the bearing caps and wheel centres, replace the wheels and spin each by hand in turn, listening with a long screwdriver or bearing stethoscope (they are only a few quid for a cheap one) on the end of the stub axle shaft. You should hear a clear difference if you have one bad bearing, but you might find both have some noise on the Jazz, if they haven't been done.
I guess if your hearing is not 100%, you may need an assistant for this.
Worked for me, I replaced the noisiest sounding one on the nearside, and all was quiet again. I expect the offside one will be the next...
I am pretty certain mine are noisier than they need be, but it has passed at least 3 MOTs like that so maybe I am mistaken.
Ours sounded horrible, but didn't get a mention on the MOT, so it is possible. When the weight is off them, they feel okay.
