Hi all,

Relatively new to ATV repair and maintenance other than the standard oil changes and such. I've got a 2012 Honda Rancher TRX420FM that has a squeaky, grinding sound coming from the right rear wheel and I suspect the issue is a worn out bearing. Looking at parts lists, it appears the right rear bearing is located in the final gear assembly (rear differential?).

How difficult is it to replace just the bearing? Does anyone have a link to a good walkthrough, or could provide instructions?

As far as parts go:
Do I just need parts 37 and 40?
Am I better off buying a new final gear assembly (part 11 from the link below)?

Thanks so much for any assistance!
