Many posts have mentioned checking the wheel bearings, but I can't find exactly how to do this. Does my 1978
Burro have bearings that need to be removed to be cleaned and greased or do I have grease fittings somewhere (can't find any!)? Do I pry off the dust cover to find the bearings behind the locking nut? Do I need new grease seals to do this or can I reuse an old seal? Any help is appreciated!
