i had the exact same issues described here,
the axle seals were replaced by mechanic somehow still leaking, i will check it out tomorrow.
for me the clunking at least was the right front wheel bearing

hope this helps

 

yea, if it's the gap between the axle and the passenger side tcase seal that gap is normal. Made a thread about that awhile ago during an install cuz I didn't think it looked right and got it confirmed.
