i have a knocking noise coming from the front left of my 306. i am not sure if it is one or two problems. firstly when driving, especially when driving slower (round town) there is a knocking coming from the front left. it is worse on bumpy roads but hardly happens at all on fast roads. When turning left there is a slight grinding noise which is worse the tighter the corner. secondly when driving in gear (and only in gear) at low revs the knocking noise is quite loud, but not apparent when accelerating . at higher speeds the noise is not apparent. i have been told i need a new back axle as the bushes have gone and have already had a new carrier bearing(bottom bearing) and driveshaft on the left. it seems like the driveshaft is not being held in place properly. could it be the wishbone/anti roll bushes/steering rack/ droplink? pls help as my car sounds like a precussion section!
