I have a Kent Glendale with dual front suspension. The top half of the fork is turned around so the right shock was installed into the left stanchion and vice-versa. and I cannot figure out how to remove the lower half of the fork. There are no screws on the outside, just a rubber stopper at the top of each stanchion tube and a nylon split washer at each joint. Looking down through the tubes, it's just a black hole for several inches.
After a little Google research of this bike, you can see that the fork is assembled correctly. What's going on is that the crown (the part the stanchions attach to) is bent/twisted or the steer tube (the tube that runs through to the handlebars) is bent. Either way, you're going to need some mechanic work or a new fork.
On a side note, you can probably remove the stanchions from the crown, but judging by the amount of rust in your pictures, they're probably fairly stuck by now.
