Ginge !

ok my impreza has a knocking noise, the N/S/R is prob the most notible but the whole car seems to knock from all corners when driving slow,,,,, the suspension feels fine though apart from rock fucking hard that is

so does anyone elses knock when driving or are my coilovers just fucked

Coilovers are friggin noisey bruv especially on the near side, on cossies the near side needs relieving with a club hammer

It was the same when mine had coilovers, as charlie says the only way to sort it on the saff was to use a hammer!!!

So i chnaged mine for adjustable konis.

Ginge !

impreza's have mcpherson struts as standard so theres loads of room, just tt knocking i aint got a clue what it is,,,, which is worrying

Sounds like you have clearance issues.

Coilovers are harsh but there shouldnt really be a noticable knocking noise. Mine never made a noise.

If the dampers are adjustable, maybe adjust them to soft and see if theres a difference?

If not then get under there and find out where they are making contact with the turrets.

Ginge !

problem is i changed alot of parts at once, ive changed the roll bars, bushes all round and coilovers too,,, so i would have to back pedal to find the issues

Ive changed a fair few arb drop link's on Impreza's due to knocking.

Ginge !

mine are rose jointed, think im gonna whip my rear roll bar off and see what happens

Rose joints only need a tiny amount of wear to start them knocking....hence why they aint recommended for our shite roads. I used to run Bilstein coil overs on the 3dr and the rears were rose jointed at the bottom. The knocking from them drove me to sell them and fit a set of cheap AVO's insted

its probably the coil over topping out.. ?

Gaz ones seem particularly bad for noisy 'top out'

both on their coil overs and normal style adjustable shocks.

As peevee said either 'topping out' or in the case of mine now the spring rattles around due to how the height is adjusted and without helper springs to take up the slack they knock sometimes due to the spring coming off it's seat then going back in again. This seems to be most noticable round very tight bends where the suspension is unloading or over potholes etc.

my GAZ golds on my fiesta Si were a bit knocky on the back sometimes, wasnt consistant though used to come and go.

Ginge !

this is on slow rolling in straight lines aswell as turning,, its comming from the N/S/R, its top mount knocking but could be the sound traveling as i dont have rubber top mounts, its just metal on metal with pillowball top mounts

could a cv joint on the rear do the same noise perhaps ?
