Front End Rattle After Off-roading

[clark]

My front passenger side wheel rattles during off pedal...I mean 'coasting'.
It only rattles when off-throttle. If I step on the gas even very little amount, it' doesn't.
I found the crack at the differential mount which is on the crossmember...so I changed it, but it wasn't a culprit.
Check this out.

My next suspect is a half shaft, maybe the next one will be a diff.
What do you guys think? Hopefully everyone could understand my English.
Thanks.
