I only drive this a time or two a week, maybe 20 miles a week. About two or three trips ago I noticed some whirring noise that I just attributed to a rear brake issue I was aware of but yesterday it just got me curious to look and what I’m assuming now is no fluid in the case, or low. I got the gasket and oil to replace just looking for any feedback from all of yall. Does the whirring noise mean damage beyond just a gasket and fill up or am I looking at more significant damage done?
