Schwinn Wold Sport Rear Hub
I'm wonder how the mother to take the rear hub apart. I only need to get to the bearings so I can lube it up as its making quite a squirly racket when it moves. Do I need chain whips and a special tool to remove a metal bar thats inside (perhaps I'll get pictures if no one can point me in the direction of tools)
If it's making lots of metallic screeching sounds, the hub may be shot. You need to remove the freewheel or cassette before servicing the rear hub (at least it makes it easier). You'll need cone wrenches to remove the cones, which give you access to the hub cups. Inspect for pitting/damage.
