Knocking from under the car.?????

[crespo]

I have a slight nock that can be heard going over some bumps, its not a huge knock but there is defo a knock there.
I have checked all the bushes and suspension components and they are all perfect.
I also checked the exhaust system and that is also good.
Anyone else had a knock and got it sorted. Maybe i have missed something.
I was thinking engine mount but it seems unlikely.
Any ideas.

Radiator mounts can give a knock, is it coming from the front or the back?

Its hard to tell mate to be honest. I think its the front but the misses thinks its the back.
But then what does she know. Ill take a look at the radiator tomorrow when i whip the bumper off to fit my HID kit.

Did you check the rear upper control arms? They are best checked while the car is on the ground

Yeah it was checked in a pit with a wobble thing. (you know so you can rock the car from side to side to replicate going over bumps) I could hear it but couldnt locate it for the life of me.

Go out and grab the top of the rear wheel and give it a few sharp tugs, that will definatly eliminate them. Also arb bushes can still clunk even although they don't look worn

Did that and all was well.

Ill double check the ARB bushes as well tomorrow. If it comes to it i may change them anyway if the clunk carrys on.

thats what i did mine were perfect but i changed them anyway and the car didnt knock since i changed them so even the slight gap could make it knock
