Hey all, I've been loooking for a used 80, and the Newbie guide on the Slee page says to look at the knuckles and see if they are covered in grease or not. Please excuse my ignorance, but being a complete newbie, I'm not exactly sure what I am looking at. I'd like to learn however. Could someone please post a photo of a normal-appearing intact knuckle, perhaps with an explanation of what is shown? And maybe give me a hint where there should be grease and where there should not? I did use the search function, but found only pictures of disassembled knuckles. That doesn't help much. The 80 I looked at today was a very poorly maintained specimen, and there was gobs of crusty grease all over the ends of the axle just outboard of the axle housing (beyond the joint itself). I'm guessing that's bad. Thanks in advance!
