Loud noise on over run

[mad in general]

Got this strange rotational noise when running down the revs in gear.
Really loud and is almost like a whump whump whump sound. I know that sounds daft but will try get a recording.

Anyway. This noise disappears completely the moment the clutch is pressed in.

I can faintly hear it when on light throttle but it is not obvious when on power.

Any ideas?

The clutch?

 

[gavinf91]

pop and bang remap?

 

[Hxrry]

Maybe a gearbox fault?

 

[mad in general]

The full clutch kit was done along with a gearbox refurb only 15-20k ago. Hopefully neither of those!

No remap, standard engine wise.

It does seem like it's got to be a box fault though as it's only when in gear. Knock it out or clutch in and it disappears instantly.

It would appear this drive shaft bearing is ruined. This'll be the source then.

Is it replaceable or a new shaft?

 

[JamesBryan]

Centre support bearing should be replaceable 🤔

 

[Krarl]

Yeah the bearings are replaceable.

I'm sure they're the same as the Megane 225/R26/175. Message MND Motorsport on Facebook, Matt is usually cheapest and best on delivery of the bearings

Would I need a press/puller or just some persuasion?
Cheers.

I knocked mine off with a big hammer and knocked the new one on with a bit of scaffold pole

Just run without tbh

Can you?

Hi btw

 

[Djw John]

Oh hai.

yeah, ran the rb without it for god knows how long. Ph1s don't have them at all.

Interesting.

What purpose does it serve? Not that I doubt you for a minute.

 

[Djw John]

I actually don't know the point of it but I do know that I couldn't tell if it was fitted or not, it made zero difference.

 

[Krarl]

You'll need the PH1/Cup shaft, you can't just have a wobbly f**king driveshaft😂😂😂

 

[Djw John]

No you don't. The bearing is on the shaft but there's not a join at that point so it's not floppy at all. Unlike @Pudding of Yorkshire
I reckon it did 25k and at least 6 track days like that.

 

[Krarl]

The bearing is the centre support on the shaft, without it it would just flop around surely

PH2 Shaft below with bearing

172 CUP/PH1 shaft below which doesnt need the bearing

I'm intrigued to know how the f**k your shaft didnt put a hole in the block without the bearing 😂

 

[Djw John]

It wasn't and it didn't.
I can only speak from experience. And I'm not known for being a gentle driver 😂

 

[Krarl]

You absolute pikey 😂 😂

 

[Djw John]

Hi there.

 

[mad in general]

So 50/50 then...

John, are you encouraging me to bodge it?

@Pudding of Yorkshire are you Kyle? Am I likely to cause damage without this bearing?

Cheers

Dave

 

[Djw John]

Absolutely 😂😂

Aye tis I, Kyle of Yorkshire 😂

Tbh if John said it's sound then just remove the bracket and bearing. If it goes tits up blame him, 100% blame him 😂

 

[Djw John]

I'm married and the dad of 2 girls, you think getting the blame for something bothers me?!
