Wheel bearings on a 172 Cup...talk to me.

[ex-Chinese Dave]

I have a slight whine around 25-35mph that is there when I dip the clutch. I'm pretty sure it's a wheel bearing but not sure which. I'll be jacking it up on Saturday to find out.

I did one or two years ago on my XR3i but what are they like to do on a 172?

 

[Mr Trailer Man]

You're not doing them yourself unless you've got a decent press in the 10-20ton range.

 

[ex-Chinese Dave]

That's me told then.

It's at Birchdown for a service and fuel pump in a few weeks so i'll be asking the chaps to have a go.

Cheers.

Haha sorry mate, they're not a simple bolt in job like a lot of modern stuff now.

Hopefully it is just a bearing and not the gearbox.

 

[Advikaz]

They’re a pain in the ass if you haven’t got the right tools.

I got @FrogJam Motorsport to do mine after someone else cocked them up resulting in me having to buy two lots of new wheel bearings. Yay.

Frogjam did a great job.

It's not the box as I've just had a refurbed box put in. When I dip the clutch the whine is constant. It's not bad but these things never get better.

I thought when a wheel bearing goes - the faster you drive the louder it gets?

 

[ex-Chinese Dave]

When they start to go there’s usually a light humming noise to start with and I think that’s where I’m at. I’ve not noticed it at motorway speeds but there’s a lot of other noise happening at 60-70mph. When driving gently up to 30-35mph it’s noticeable.

I think the noise is coming from the n/s/r so if so maybe it’s time to do the discs on both sides (I was thinking of this last week coincidentally) as I’ve read that the bearing come ready fitted in the disc.

 

[Colin-S]

Yeah the rear bearings are supplied pressed into the disc.

 

[Advikaz]

Get SNR rear discs from AUTODOC.

Oem.

 

[Jamie86]

You can buy the bearings as well though if discs are fine. Most garages would press it in for you for a drink I’d imagine.

Just more to go wrong. And they’re not expensive to replace the whole disc mate

No agreed. New disc is easier option but seem to remember prices have jumped recently? But then not bought any Clio parts for a while.

AUTODOC always makes my head hurt tbf

 

[Jamie86]

Tbf genuine aren’t as much as I thought they were.

They were almost double that price when I looked a few weeks ago 😲

Genuine are SNR. But not bad for Renault boxed

Cheaper ones have wrong abs ring tooth count.

Easy enough to change.

Which doesn’t matter at all to a cup 😉

SNR make the genuine discs as well? I know they do the bearings. Which is the main thing tbf

I know, but in Adz's case who linked them it would.

This car of mine did about 1500 miles in about 11 years before I bought it last year. Now that it's my daily it seems that 11 years of almost no maintenance has caught up on it.....but I still love it. Aww.

Sat there doing nothing, things seize up and as soon as you use them it starts to show.

Like collectors of supercars, hardly any mileage on them. As soon as they start them up the engine starts leaking as seals/gaskets dry up and they piss oil.

I've just jacked it up and checked the wheels. Tyres are all normal and rocking all the wheels top to bottom and side to side I can feel no loose play at all. When spinning the rears the o/s rotates fairly freely and the n/s less so. They don't spin easily and continuously and there is the usual sound of the brake pads touching the discs a little. Having typed that I wouldn't say there's a lot of resistance to spinning them either. Would you opt to change them?

I could also be that bloody exhaust!!!

Anyway, I off to ruin a good walk on the local course.

Could be a seized/seizing caliper

 

[Mr Trailer Man]

Yeah that's just the caliper stopping the wheel spinning freely, typical really.

 

[ex-Chinese Dave]

I think a little corrosion on the disc fouls on the pad.
