Rear tick/knock

[qsilverza]

Hi,

(I think the problem is just the exhauast.)

Just got my V6 4motion. It was checked out by RACV and my mechanic. Only things the found were a seal on the rear drive shaft and the front cv joint which has been fixed up from my knowledge.

When going over a large bump at slow speeds I get a tick/knock noise coming from the rear of the car for about 10 seconds after going over it.

P.S.

How do you tell what sort of alarm you have ? I.E. If it is motion sensing,ultra sound etc etc

Thanks !
