Title: Rear wheel bearing noise
Post by: chrisgixer on 25 May 2015, 19:13:48
What does this sound like? And what affects it? Ie cornering or braking etc...

Also apparently these don't show any play in the wheel. Is this correct?

You talking generally or omega specific, Chris?

from what i've seen in the shop we've had two cars with front bearings shot....weirdly NO NOISE but 12 and 6 play was stupidly obvious.

my ma's ford fusion rear drum bearing went and at 25-30 there was a properly loud rumbling noise.....but NO PLAY. however spinning it by hand on the ramp was a horrible loud grinding sound that was a lot more than the sound of pads on discs.

so what im saying is... could be noisy, could be play but not necesarily together  :)

Omega ones in this case.

dont see why they should be any different tbh.

but as to your initial post... if one's noisy it wasnt during braking or cornering.....noise was constant at certain speed (i.e. really loud 25-30 then got quiet at 50+

hth  :)

Yes I remember Entwoods thread. He diagnosed his by jacking the rear onto stands and running the car in gear. Which I have done. There's no noticeable noise I can hear anywhere.

...but as the wheels are unloaded in that instance I sort of presumed towards wheel bearing.... Thought occurs, wheels will also be hanging so not in the usual position as far as position of drive shafts etc. so not conclusive.

So far...
Hand brake adjusted.
Discs and pads checked and lip on discs ground flat on both faces.

It's not brakes. Although brakes dulls the noise slightly.

It does lessen slightly in left handlers.

It's not a constant noise. Woom woom i "think" in time with wheel speed not prop speed.

Tyres perhaps?

The three I've done had lots of play and moaned worse than a wife. A noise that got louder and deeper with speed.

Its a weird sound but if not brakes or bearing, could it be wheel or tyre related as it did quieten down on a left turn.

Drivers rear tyre is slightly out of round/not seated correctly perhpaps, but noise seems to be more to the left/passenger side which has slightly more tread, and I can't fault the trueness, it runs perfectly round.

Tyres are Conti sports contact 3 and while not very quiet as tyres go, they have never made a droan in all the sets I've had. Those other makes that did, like linglongs (sigh) where quieter at speed and progressively louder as you pulled up to a stop. Like undoing a zip at decreasing speed. This starts quiet and gets louder from 20mph up to its loudest at 40-50mph where it's gradually drowned out or becomes a constant.

If a tyre noise I'd expect it to be present at all speeds and worse under load, like braking at the front or acceleration in the rear. But only side load has a slight effect.

Although I do have another pair of wheels I could fit to discount tyre noise.

Got to be worth a go before owt else :y

Yeah, I have a 'lub lub lub' noise under slower speed cornering (eg: spinning round in a cul-de-sac) which I am suspecting to be a poor tyre. Knowing the front suspensions is basically brand new, it's either tracking (yet to get this checked) or tyre.

Does it come and go with cornering? If so, the unloaded wheel when cornering is at fault.

It gets louder at speed?

Didn't you hear mine?
Title: Re: Rear wheel bearing noise
Post by: chrisgixer on 27 May 2015, 01:04:45
Honestly, no. :(

Or at least I didn't here what mines going when driving yours.

Pull away nothing

10mph nothing

20mph nothing

30mph noth.... Oh what's that.... woom   woom   woom (bollards it's still there)

35mph woom woom woom

40mph woomwoomwoom

50mph womwomwomwom

Etc

Turn left and it gets slightly quieter. :(

Yep. That reminds me of last summer's wheel bearing issue  >:(

Try driving at 80mph down the motorway for an hour and if the noise hasn't driven you to feel like actually getting out of the car while it's still moving then the wheel bearing isn't quite toast yet!  ;D

Post by: chrisgixer on 27 May 2015, 02:01:47
It's not too bad at 80 so yes I still trust it ;D

Post by: Lazydocker on 27 May 2015, 10:22:26
Sounds like n/s wheel bearing. Oh... And mine was fixed before the holiday.

Rear bearings rarely fail with play, just noise. Mine had gotten to the point you couldn't talk normally when travelling at any speed greater than about 40 :o

P.S. I'll have a listen on Saturday if you like?

Oh that's ok then, thanks Ld I feel much more reassured as it's nowhere near that loud yet ;D


And yes that would be good thank you :y
