Long story short...I winched a friends tractor out of the ditch a little while back, in park with the diffs locked. It was a struggle but got the job done. A few weeks later I realized it had busted off the outer hub drive flange on the passenger side. I replaced the entire assembly (bolts had sheared off in hub), and all was good...for a minute. Now it has popped the dust cap off again, and there is a clunk sound in the front diff that increases with speed. I have pulled both axles expecting to find a broken one and they are both good (RCV axles). What else would be clunking in there!!
