Things That Go Bonk.

Okay all of you defender wizards.
I have a small problem, when turning into a right hand corner i get a bonk noise which seems to be coming from around the rear axel area, sorry that i cannot be more exact. Have tried to tie the wife to the underneath to listen where its coming from, but she wasn't having any of it Any suggestion's what it might be.

check ya A-frame ball joint, followed by all ya bushes.

Rear damper bush?

Many Thanks for your help lads.
