I'm currently working on a '88 with the stock 10b up front. I removed the hub but I'm at the point where I see the wheel nut w/ 4 slots. The problem I'm having is that there's what appears to be a small round nut in front of it with a 1/4" slot in it. My question is... is that part of the wheel nut? If not, how the heck do you remove it? I tried tapping it lightly with a screwdriver then decided to ask the experts before I mess something up... Could someone let me know asap.. Thanks!
