Hi there can anyone help me please I have a 54 plate wrx impreza not had it long and its the first one I've owned and I have a really annoying knocking/ tapping noise I cant seem to find it??? It's like the spoiler is banging on the boot lid but if I rock the back of the car up and down from inside of the boot you can hear it like it's coming from the back wheel on the passenger side??? Anyone got any ideas cheers

 

Probably the shock absorber or anti-roll bar link mate

 

Sounds like similar I had on my Hawkeye. If you carefully lift the boot up on the passenger rear shock and spray some wd40 in there and see if it is still there.

Hope this helps - works with mine 6months + down the line and still ok
