The last two days I have been haing knocking noises which sounds like its coming from behind the steering wheel area or could be the around wheel, only notice it under 40mph ( because of the load exhaust noise ) and goes faster as you exceleration and stops when break pedal is applied . I found a huge spring on my drive and it was not their a couple of days ago when this knocking sound was not present.
Can anyone I'd the culprit or is it nothing to do with my problem and just a coincidence it is their

 

thats a exhaust spring normally found on the back end of the cat to centre

 

Oh is it, we'll I will take a look but now I am confused even more

 

Two long bolts with springs on holding the joint together.

 

Definitely exhaust spring bolts rust and springs breaks free
Suprised if the exhaust isn't blowing

 

Exhaust seems fine, its a straight through de cat . Makes me thinks if its a neighbours and its blown over, doesn't explain my knocking sound though.

Thanks for the replies guys

 

yes you are correct

 

A car I had, the handbrake cable came unclipped from the car's underside, and made contact with the rear wheel. Every time the balance weight came round it "bumped".
