General Strange Knocking noise When turning right

[SgtMunky]

Hi all.

Recently had a good friend (also a good mechanic) do my MOT and while he was at it, check around my wheel and wheel arch's to make sure nothing was hitting. When turning right, with 2 or more passengers, I get a constant knocking, which knocks faster depending on my speed

I just replaced the shocks, to no avail too.

Friend say's he doesn't know where to start really, as its clearly a travel noise, and the CV joints are only on the front driving wheels (or so I believe)

Anybody had this before? Driving me crazy

Check the wheel nuts/studs for tightness, immediately.

I guess this is coming from the back as the CV joints are on the front and would be prime candidates if the noise was coming from the front.

Thanks for you're reply!

Well yeah we are 99.5% sure its coming from the back, and we had the wheel off and back on so def. not the nuts...

tbh I'm going to give up, looks like its a 'I had a car like that once, made a funyn noise and I never found out what it was' sort of thing

I paid £950 for her, so I won't expect much off her, but she has been and still is brilliant, LIVE ON PUNTO :slayer:

Lift each corner and try moving the wheel in and out at 12/6 oclock and 3/9 oclock positions. There should be no movement at all.

Hmm yeah don't hurt to try, cheers

But as I said, my mechanic couldn't find a good reason as of yet :/

Are your sure it's not a CV cracking turn full lock
and drive in a circle turn the wheel the other way
full lock and drive in a circle.

If you hear a cracking noise from the side on fullest
lock suspect the cv joint.

right i'll try that at tesco in the morning, see if I can get anything by myself. I'm right in thinking a worn CV joint will make noise on full lock without the need for the extra weight right?

And would I need to go forward or reverse? May sound stupid but I'm read a few random bits lol

 

[sixpotman]

Forward full lock about 10mph + window down if you hear
crack crack crack noise which increase as your
speed does then it will probably be a cv joint.
No extra weight needed.

tried that, didn't do anything :/ but if I get one person to sit in the back passenger side seat and do a long fast corner or short sharp, it does it

i had that problem turned out it was a buldge in the tyre, as i was going round a corner it was hitting the buldge i didnt realise it until it created even more buldges so that the whole car was constantly vibrating! lol :bang:

hey,

this might not have anything to do with the knocking noise u are having trouble to find but on my punto on locks i kept getting knocking noises and after checking over i had loads of play / worn ball joint. as you said u have had a mechanic check it over so it may not be the case. the cv joint may have something to do with the knockin sound.

yeah CV joint is very common, but don't we only have them on the front wheels?

 

[sixpotman]

CV joints on drive wheels on punto - front

Try jacking the back wheel up and spinning the wheel
it should sound quiet if there is any noise it may be a wheel
bearing.

Actually thats a very good idea. Although it seems like the weight in the car affects the noise... If I jack the suspension up on that wheel, will the unladen weight of the car be enough to properly compress that side of the suspension? (this made sense in my head )

 

[SgtMunky]

sod it, selling shop and getting a golf lol

The clip that holds the handbrake cable by the exhaust was tapping the exhaust pipe under load ¬.¬

Come to think of it my zorst used to rub on left-handers, but it clearly was the zorst.
I put a jubillee clip on each mounting peg to stop the mounting rubber sliding too far along.

Hey ... These seem to come from the Wheel caps !! ... Give a test drive without wheel caps... There should be no knocking sound !!!
