Somes times i go over speed humps and my car knock and other times it does could this be the suspension if i drive fast it knocks and if i drive slow it dont or is it the exhaust scraping

couldnt really say without seeing it,, but that aint the greatest explanation

i cant make much sense of that ?

do you get knocking noises only on speed humps ?
or turning or even in a straigh line ?

explain it with a bit more detail and someone will be able to give you an idea

Could be the ARB link or just ARB bushes that are causing the knocking noise, then again it could be a duff exhaust bracket/mounting.

Matty

is it when you pull off hast also could be a bracket loose i.e gearbox mount or something like that, with out having to look it's polly going to be somethin with the suspension like matty said or ya top mounts ?

give us a better desciption mate and where you think the sound is coming from and might be able to help

It seems like its coming under my seat area so it could be the bracket but if i hit the speed humps in the middle it doesnt make non sound but if i hit it frm the left side it makes a noise... Its just a case of goi8ng slow over speed humps... but if it was my suspension would u hear it creaking even going slow?
