I spent a perfectly nice day inside tearing apart the final drive.
It wasn't too hard but it raised more questions than it answered.
Where did all the brass flakes come from?
Where did the lose Ball bearings come from?
Why are there 3 small mangled springs laying inside the case?
What ate the brass washer and left the crumbs all over?
What do I have to replace to fix it all?
Something bad happened and the only thing I can think of is one of the bearings
in the gear driven hub, if it has any, failed badly.
