Expert:  Chris (aka- Moose) replied 6 years ago.
Is it a single occurance or is it more like a vibration like something is binding?
Customer: replied 6 years ago.
single occurance
Expert:  Chris (aka- Moose) replied 6 years ago.
So far I am not believeing this is a bushing or joint but a concern with the AWD transfer case applying to much power to the front axle. This is a simple thing to diagnose. Remove the front driveshaft and drive it. If it still occurs then do continue checking the mounts and joints. If the noise stops then the viscous coupling clutch inside the transfer case is faulty.

but would i be able to feel the clunk under my feet
Expert:  Chris (aka- Moose) replied 6 years ago.
Yes that is where you would feel it since the front axle and and transfer case are mounted to hte frame running under your feet. I am not stating to replace any parts at this time, that would be guessing. I am telling you to do a short simple test first prior to replacing any more parts. You need to neutralize the situation and find out whats causing this rather than just replacing parts like in the past.
