Strange Knock from rear (suspension?)

G'day
As i'm driving along a road sometimes i'll hear a pretty quiet (but loud enough to annoy me) knock coming from the rear of the car, (going over a bump) at first i thought it was my tow bar loose, as it sounded exactly like that. but upon inspection it turns out to be perfectly tight. could be rear shocks be on their way out?
Cheers!

Re: Strange Knock from rear (suspension?)

Mate has your car been lowered?
It may be the driveshaft hitting the tunnel.
Or a worn bush in the control arm.

Re: Strange Knock from rear (suspension?)

no my car atm has 4x4 ride height, it's really bad, with the EF all-famous fairmont alloys. I'm getting around to putting new rims on and lowering. as soon as i get the cash

in short, my car hasn't been lowered. it's prolly just a rooted shocker!

oh oh and squeeky springs? whats the deal with that?

Re: Strange Knock from rear (suspension?)

well judging by the first response i got..... better off to ask a dead man with no arms or legs.

Re: Strange Knock from rear (suspension?)

Re: Strange Knock from rear (suspension?)

is it like a hollow thump - like sumthin in the boot bouncing?

if so dont worry bout cos every model falcon i've been in from el to au does it.

My wifes EL Futura does it, my AUXR8 does it - and it has irs and my mates AUXR6 does it.


Honestly i think its the spare or even the jack bouncing on the tank well (yes it is bolted in tight) and it only happens on certain bumps.

Anyway thats if its the same sound
