Horrible noise!!!!!

Afternoon all, I am looking for a bit of advice please.

 

I am currently getting a really bad grating whine when the car is moving, when on or close to full lock. It is especially loud when cold and seems to be getting worse.

 

Does anybody have any idea what it might be? It is getting quite embarrassing, especially driving into a very busy multi storey car park yesterday:D

I just checked the fluid, the only marker that is on the mini dip stick is the word "HOT". The fluid is currently up to the H and seems pretty full at the moment.

 

open the bonnet and look at your aux belt. At its lowest point it goes round the crank pulley. Look down at this and see its it out of line with the others ie looking from the side its nearer to the front bumper/rad than the others. If it looks in line then keep looking while you get someone to do what is necessary to get the whine going and see if it moves then too.

 

Basically the lower pulley can seperate and this often causes a whine before it fails, and the full lock of the steering puts more strain on the aux belt and therefore the other pulleys, so it can start off only whining on full lock.....

 

it may be the Power steering pump etc but it well worth checking out the crank pulley............

I had this about a year or so ago, I like you feared the worse, but you won't believe what it was.

 

Take the front wheels of and bend the dust covers on the back of the disc's back away from the disc's a bit, thats what I did to mine and it hasn't done it since, still don't know why it was only doing it on tight locks, but it doesn't anymore, so all is good

thanks for all the advice guys. Due to being a complete mechanical numptie, I am going to get it booked in to my local garage straight after christmas to get it sorted at the same time as being serviced. :)

 

I will post up after this has been done and let you know what the problem was.

If it's the crank pulley then I wouldn't drive it until it's been checked.

Hi Garfy,

where is the dust plates, what to do?

or , how do I know if its the fluid or the pump need to change?

fluid level seem ok, a little brown-ish colour, is that need change anyway?

 

cheers

 

the dust plates are the big metal plates on the back of the brake disc's, I know it sounds weird and not likely to be the problem but it worked on mine and it costs nothing to try, just jack the car up, take the front wheels of and push the plate away from the disc, worth a try my thinks.

 

It is a metal scraping type noise isn't it?
