I have a 97 Rodeo and had it in 4 wheel high and have taken it out of 4 wheel and now there is a clunking sound coming from the rear of the rodeo when ever i take a sharp left or right turn... any ideas???

maybe your shackles that hold your leaf springs in place are worn and is causing the clunking.

what is a shackle and a leaf spring....and where are they???

Could be a coincidental exhaust pipe thats loose.

Could also be that your jack is loose and banging around in its mount.
