[s-cars] suspension cllunks? noise?

[Alvin Labonite]

I hear this sort of clunk when backing up while turning the wheel at the 
same time.. It also happens when pulling in a driveway diagonally but not 
when pulling in straight where both wheels lifts up at the same time. I've 
checked underneath and everything is tight. Sway bar bolts/nuts are tight 
and they have fairly new bushings.. Both strut collars are tight. It seems 
to be coming from the front only and it is really annoying..

Any ideas?

TIA
