Continue taking the wheel off, but note the position of the bushings. Lay them out on the floor in the correct order. From the outside right, the bushing in the fork { looks like a short piece of pipe } Inside the fork { looks like a piece of pipe with a large flange } The flange faces the bearing. Left side the speedo mechanism, then the bushing with the small flange. The flange goes from the inside of the fork through. Now that you have it disassembled pull the speedo out of where it sits against the bearing. You will see 2 tabs on the speedo and 2 slots on the wheel for them to fit in. Rotate the wheel a little to get the tabs and the slots to line up and point straight out through the wire guide. I don't think this is going to give you a speedo though as I strongly suspect the idiot broke your cable. Use your new nut on reassembly, but each post should have 2 washers, 1 circular and 1 lock. Check all nuts have this. Do up the nuts hand tight, once you have the axle and bushings installed spin on the axle nut but with visible space between it and the bushing. I am assuming those fender brace bolts have been slacked right off. Now shake things up a bit. Get on the bike and pump the forks a few times. Then spin the wheel and if the GS Gods are on your side it should spin freely. Then tighten everything up, fender last. I recommend using a torque wrench as you don't want brake those fork nut studs. Check bikecliffs website for the correct tension. AND MOST IMPORTANTLY REPORT BACK ! I WANT TO HEAR EVERYTHING YOU CALL THAT !@@#$$%$%ING IDIOT.
