2005 310g w' 2000 hrs has a KlUNKING sound when ever I turn left or right or forward and back. Best guess is spider gears are broke. How hard is it to replace them? Any special tools needed? Is there anything else it could be? Runs fine and will still work but don't want to do further damage. PS. This hoe is used for a lot of back filling of tile ditches. Thanks pointrow .
Have you checked if the wheel nuts are tight?
Yep!! First thing.
