JD tractor / backhoe axle grease fittings

If you have not ever greased your Deere tractor/ backhoe rear axle bearings.....On top of the axle tube right behind the axle flange where the wheel attaches, there is either a plug or grease fitting hiding from you. This plug [ if never greased} or grease fitting should be on top of your to do list. This plug or fitting sits straight on top of the axle tube and can't be seen from below. Reach around the axle tube end and feel for it. Some models don't have this and are lubed from oil.. I've seen someone get charged 10 grand [ yes folks] 10 grand to rebuild both final drives and do a lot of unneeded other work. Like taking the backhoe off a 410 when it wasn't needed to remove final drives. I have [ when in my prime ] removed and rebuilt both in a 10 hr day. That boils down to $ 500.00 in labor plus parts. I don't think the parts were $ 9500.00.... This also applies to Wheel Loader 444-544-644 series loaders. Grease them until you see a little grease come out the dirt seal at the axle flange. To check axle bearings . Block front tires.. Raise up your machine on jacks or backhoe stabilizers just off the ground. Push in on the tire , one side at a time. Any inward motion indicates lose bearings and need rebuilding the finals. The book says remove backhoe.. Don't do it just remove 1 pin on the tie bars and jack the tie bar up and force it up enough to clear the final. I pull them out and tip the axle down.. Piece of cake...
