Just driving along today and started to hear a knocking sound so I pulled over to a buddies house and checked it out to see where it was coming from and the rear axle had a little bit of fluid around the pinon seal. So I started to go back and forth in his drive way and the axle would knock at a certain stop and feel like my truck was boucing slitly. And about a year ago I had a pinon seal leak on my rear axle and fixed it. So if any body had some addice on where I should start or what the problem is I'd apperciate it before I start taking it apart. And does the sound mean the gears are done for??
