250 WTF is this noise?

I worry about car noises a lot and that would have me worried.

Any feel through the wheel or pedals when the noise starts? Where does it sound like it's coming from directional wise, at the front; Left, right, middle?

It sounds to me like, shaft or box related. Although as you've already had that looked at. Possibly try another garage to check the shafts and box?

 

Look at the driveshaft carrier bearing?

 

Normally these "what noise is this?" Thread doesn't come with a video and on the rare occasion they do it's not audible at all be it YouTube downgrading the quality or whatever. But your video the sound is clear and hopefully someone on here can help!

Sorry I can't help anymore, but to me (I'm not a mechanic) it sounds rotational and shaft related.

I hope you get it fixed and if you do, please come back and let us know what it is! You could help someone else in the future!

Good luck mate.

 

Hello Semtax, I have exactly the same issue! My cars going back to k-tec Friday! Did you manage to sort it in the end??

 

Will do, should be interesting to hear what ktec say about it!

 

I get a whinning notice as well. Starts from about 30mph, seems to get louder as the speed increases.

Mine isn't exactly the same as yours though, yours sounds louder to me. But I can't be sure.

Took it to my local garage but the mechanic took it out for a drive and said he couldn't hear anything.

Doesn't help that I have an induction kit, decat and cat back exhaust lol

 

Probably no help whatsoever, but I had a sound that 100% sounded rotational and it turned out to be a loose / bent exhaust heat shield.

Just in case it could be loose trim or something that you'd not expect.

 

@Nigelo not a bad shout that, I've had a lot of exhaust work done, so it could be that

 

They said it's the diff bearings and gearbox bearings so they are putting a reconditioned box in next week! They have been very helpful so far! Will keep you posted

 

That sounds expensive.

I hope I don't have the same issue

 

Anyone else had any luck with this? Looking to get mine checked out today

 

sold my one before it got expensive after having to replace all four discs and lower swivel bearings plus drivers side front wheel bearing thinking it was that that was making the noise on top of shelling out for a full service plus belts . ouch ! Hate to say it but it's much more stress free driving the new motor in silence without having that discernible whine which no one else says they can hear. thought I was going mad but judging by the posts it seems to be cropping up quite a lot on the forum.

 

I have this kind of whining as well, my ball joints are new by the way ... It is weird it only follows the speed of the car, not the engine...

 

That's the noise mine makes above 70mph

 

Yeah I had my ball joints replaced last year sometime. Definitely been less than a year.

Mine also gets louder with an increase in speed, at 30ish you can hear it slightly, at 50ish it's slightly louder and then at 70+ it's like the video I just posted

 

Yep I got a Cup so I have a LSD.

Garage I took it too said it sounded like a gearbox/diff whine, so I'm getting my gearbox oil changed on Saturday. See if that fixes the issue.

 

That has to be Gearbox or diff related !

 

Yeah that's what my garage said. Getting my gearbox oil changed tomorrow.

Then we'll see what happens.

Got warranty, so hopefully they cover the cost if I need a new box

 

Yeah I can hear it from that video too.

Can't be normal can it?

Had my gearbox oil changed but it didn't fix the issue. It's definitely coming from the LSD/gearbox though

 

Hopefully my warranty company cover that. I'll have to call them today and find out what they say.

Was the £600/£700 for just replacing the bearings or for the new box?

 

@-Jamie- okay cool, thanks for the info. I'm assuming mine must be the bearings as well.

So if my warranty company agree to paying for that, I'll get it done as soon as.

 

I'll be going down the same route too, at some point.

 

Hello Semtax,
Yep picking mine up from k tec in the morning hopefully it will have solved the problem...too many people with this issue now needs to get sorted!

 

@Semtax where did you get your box refurbished or did you buy a refurbished box?

 

Mine has seemed to cure itself. Had my gearbox oil changed in Feb, and over the last few weeks I noticed the noise has gone. Maybe the oil change helped.
