Nissan R50 knocking noise rear passenger side

[The Green Machine]

Hi everyone, new to the forum and have read through all the Terrano R50 posts - great stuff there.

I live in ChCh and have just bought a 1998 R50 QD32 out of Wellington which my 7 year old son has dubbed "The Green Machine" (for obvious reasons). Good ones are hard to get in ChCh and overpriced (relatively speaking). It looks mint and is ultra tidy inside. Is a GM3R and has all the bells and whistles includes the "lovely" rear wing!

Only problem is a knocking noise in the left rear, particularly evident when you go over a bump when turning. Funny but no noise going over a bump straight ahead, although going over a large bump at a bit of speed can "bottom" out the suspension (getting worn?)

Also a creaking noise (spring?) left front when turning at slow speed.

Any help would be appreciated.
