rear axle noise

[guest4512]

Just bought a new sport on a 2005.

When I test drove the car, I heard the familiar high pitched humming noise from the back and thought there's a bearing needing replaced.

However, got it checked out and garage says no bearing defect, but the discs are pitted and rear tyres are cheap noisy ones - see other thread on Wanli tyres.

So, I've replaced the tyres and discs and no discernable difference noticed. The noise is still there at pretty much all speeds, i.e.from car park crawl and upwards.

Had car looked at by another garage today who thought bearings were ok and postulated that the rear offside caliper might be binding slightly.

Anyone got any other ideas?

Bearings.. almost certain..

whats the mileage?
I agree with madafish wheel bearing rumble most likely.

Is it the worn pad warning noise? Have a look at the condition of the pads, but the garage might be spot on with a sticky caliper.
Rear bearings are an easy earner, so they would pick them out if they thought that was it?

[guest4512]

I've had the bearings checked twice, no movement. Discs and pads were done 2 weeks ago.

I don't think the caliper is binding as had it on a ramp yesterday, while one wheel didn't turn as freely as the other, it wasn't binding.

Another point, this noise is noticeably revolution based and starts at crawling speeds, so doesn't tie in with a bearing.

Try a garage which is competent. The ones you are using clearly are not.

If it's speed related, then it's either a bearing, the disk/pad or a bit of stone trapped between disk and a bit of metal.
Andy semi competent mechanic should be able to find it in 20 minutes.

It could be a binding brake cable, a faulty caliper .. or anything...

Binding caliper piston noise can come and go as I have experienced and when jacked up and checked one wheel may appear to be 'not turning as feely as the other'.
The noise can appear as a 'whirring, vibration' type noise that is speed related whereas a wheel bearing is more like a 'whining' noise and is present all the time.
When mine was fixed it was cheaper to replace the caliper  than spend money on freeing up the offending piston, which may not have been recoverable anyway.

I've got it booked back into my usual garage for Monday,  but just in case it's booked in to a Honda specialist garage for Wednesday.

Will let you know what the outcome is.

Just discovered my gearbox bearing is away too.

[guest4078]

OK, please say you bought from a dealer. Take it back and let them fix it for you under soga.
If not, bung gearbox Molysip in and drive with the radio turned up. Mine worked fine with the gearbox bearing fault.

Unfortunately not mate.

I'm a mug,  I heard the gearbox when I test drove the car,  but put it down as something else. My mistake really.

Will take your advice on the molyslip,  cheers.

Try it the old easy easy way. Get on a hill turn off engine but don't turn key so it steering locks then listen if its a bearing you will hear it. Either that or hammer ir around a roundabout, if its a bearing it will whine.

If not I reckon you've diagnosed yourself something with box or clutch bearing

beware turning engine off on a hill-  if the engine not running the brakes won't work too good either 

if it is a wheel bearing the noise should change as you steer right and left as the direction of load changes on the bearing.

He's referring to my gearbox input bearing. I've got double bearing trouble.

Car is booked into a Honda specialist tomorrow.
