Single clunk sound from front passenger side

I was wondering if anyone could help me me diagnoise a problem. A couple of months ago my truck slid off a right hand curve off ramp. It hit the curb and went into the ditch. Shortly afterwards the truck started to track straight, which was usual because the alignment had the truck teetering slightly left. Then afterwards a single clunk sound could be heard when the steering wheel is turned to the left 1 - 1 1/2 turns when I park the truck. The single clunk sound can also be heard under heard braking. The sound seems to originate from the front passenger side. The truck is in for an alignment now and dianosis, and Toyota thinks its a broken front axle. What is TW's opinion?

 

God, it could be a number of things. Broken caliper bolt, almost-broken axle, messed up tie rod end that hasn't broken yet, etc. etc.
