Right guys, just want to sanity check my own thoughts as to what this could be. I'm not that hot on impreza's having not long had the car but on tip in/out i can hear a knock from the rear, sometimes sounds more passenger side than anything. Anyway, it's got slightly worse recently but nothing major but it's sooooo annoying and is also bugging me into being overly sympathetic to the car. I did snap the rear drop linked but i've got the ARB removed at the mo and it's still there.
Your thoughts would be greatly appreciated.
Cheers Olly

 

Noisy shock(damper rod)?
Rear Driveshaft/Hub Nut needs re-torquing?
Is it the diff you can hear dividing on slow turns?

Process of elimination really.
