So, last week there is a terrible grinding noise from the left front of the sub. When I back up or put the sub in 4wd, the noise goes away. Soooo, I'm suspecting the front 4wd hub is starting to go, what is the best way to fix this? Warn does not make a manual hub for this vehicle. BTW, I don't care if the hubs are auto or manual.
