Strange noise from 2011 VW polo

[Daviesmith]

Good morning Ive recently had a noise from my car that sounded like brakes catching on whilst I was driving along. I went to my local garage he suggested changing all pads and discs plus when checking he also found leaking shocks so I also had them changed.

Unfortunately I still have the sound so I'm assuming it's not the brakes. Does anyone have any ideas what else could make this kind of noise ?

Speedometer cable?

If it's a scraping noise it could be the discs rubbing on the backplate that keeps the water off them.......however, the garage should have been wise to this!

It is like a scraping noise . I will check them backplates I got a stone lodged in there a few years back

Take it back to the garage they diagnosed it as brakes. Ask them to have another look for free.
When up on ramp a lot easier to see what's going on

I have had this problem on several Peugeot 406's and it was due to the brake backplates rusting between the two layers which pushed them apart and against the discs.

Hi again I eventually got back to the garage and they said it's either a driveshaft or a wheel bearing. Hopefully I find out tomorrow

Typically, wheel bearings drone when going around corners.......the noise comes and goes as the bearing loads up.
Driveshafts typically knock and clatter when on full steering lock.
Looking forward to hearing the outcome!

What's the most expensive?

Bearing noise is normally obvious, if the corner is jacked up, and the wheel spun round. Drive shaft noise (UJ), will be worse, making a tight left circle, versus a right hand one.

The mechanic said the wheel was harder to spin than the good side when jacked up

Well that will be feck all to do with the shaft! Think he's just guessing at it.

Did he/she not think to investigate why?

 

[Daviesmith]

I think they are still investigating. They are keeping my car tonight. He said he's going to remove the drive shaft to check it

Had that years ago, finally cured by driving in reverse for a short distance
