Usually... the clunking happens when u go forward and reverse. I have a friend that works at Rick Case and he fixed the problem for me. He added some grease to the inner walls of the nuts and then retorqued them. Dont forget to redent after you torque.

Thanks everybody, I'll report back the results after I try this out tomorrow.

I'm unclear on the denting so I'll just jump on google and stop being a lazy bastard
