For the last few months my car has made this strange knocking sort of noise from the rear end... when I steer heavily to the right it is more pronounced... I can't describe it any better than that but at low speeds it is quite loud... can any of you out there that know more about cars than I do.. shed a bit of light... I find it quite worrying and really don't what to say if I take it to a garage... I expect they will be rubbing their hands to together thinking... here comes a right one and a blond ...

the car is only 2 years old and she clunks and winges like a car 10 years old... not to mention that is stinks of petrol all the time... any thoughts...

thanks

Based on recent experience, wheel bearings?

More load obviously as you go round a corner...

 

Don't know if I should own up to this but I had a similar experiance recently

a knocking noise fron the rear end

I checked everything I could see but gave up and headed off to the garage

20 mins on the ramp NOTHING

10 mins remove rear wheels

10 mins technician running round the block

when he got back opened he opened the boot

10 mins laughing when he advised me my new golf trolley was the culprit

I see you've finally calmed down now then?
You may also want to check the top of the rear struts, as these clunk when loose.
Mine have done it a couple of times.

LOL @ phil stephens

Funny story m8....You're a better man than I to own up to it

 

Might sound daft, but do you have a Scoobysport backbox?? Mine knocked on the rear diff causing a clunking sound?

 

I also get the occasional knock - I pretty sure it's my SS backbox bumping around.

It's not bad though - barely noticeable and only happens occasionally.

Penni,

My Scoobysport back box would intermittently hit the left driveshaft or the rear diff, especially on right hand corners..

As mentioned, check the position and condition of all the exhaust hangers as they can stretch or break.

Get the petrol smell checked out now - maybe a loose fuel tank breather pipe, or fuel line?. Either way, get it fixed straight away for safety.

Cheers,

Alex

 

I`m surprised nobody has mentioned the rear anti-roll bar mountings and especially the drop link joints?
On cars with fuel injection there is a LOT of fuel pressure in the system under the bonnet, any weeps or leaks here is bad news. They dont fit inertia or shock switches to the fuel pump circuit for nothing!
Black Cat - I bet you are getting a bit confused by now?

Noises from my rear were found to be a loose valance end clip and the hardboard spare wheel cover not seated properly.

 

Check the hub nut. Very very rare that it can come loose, but makes a very specific "clunking noise" if it does.

I think it needs a torque of around 250 lbs to secure it tight.

Try that, take it to a tyre place and ask them to check the hub nut for you.

Hope this helps

Prety unlikely it's a hub nut loose unless you have had the driveshafts off for some reason.

Quite common culprit is the exhaust moving on the mounting rubbers and hitting the body.

Get the mounts checked out, it's not uncommon for them to break or become soft and allow more flex.

There have been a fair few wheel bearing failures of late it seems. Quick test for this is brake to push the pads against the disks, just light application then release then take a corner loading up the side you suspect, straighten up then apply the brakes again, if the bearing is buggered you should be able to feel that the pads have been pushed away from the disks and you now have to press the pedal down futher to take that play up.

Not everyone can feel the brakes that way though, just a way that works for me.

A competent mechanic should be able to trace this, if you know of one you trust just take it in and get it checked out.

 

Guys
Thanks, all your comments are very relevant and I now have some basis to get himself to investigate in our pitt.

Some of you probaby saw in my previous thread (yes I am now calm... only get made when I see some of you taking silly risks)may know that I had a major prang last year which twisted the driver's side of the car and everything was off at some stage.... it could well be any one of the issues you have highlighted.

Thanks again
Penni

 

There is a known fault that can develop with the fuel filler pipework, this can cause a fuel leak, worth getting checked out asap.

Apparantly its the first thing the fire brigade check when called to a Scoob with a fuel leak.

I was driving down a country lane and heard a knocking noise coming from the rear so I stopped the car got out and opened the boot to find the theif who tried to nick my scooby with his hands and legs all tied up in rope and thick pipe tape around his mouth. I still to this day never know how he got there.
