Hi my steel Raleigh just returned from the shop and they refused to do anything to fix my fork. The issue is this:
I hit a pothole. When I later examined the bike, the front wheel (the top part where it crosses between the fork blades) favors the left hand fork (when looking from the front) aka the right hand fork looking down as you ride. The tired is not quite rubbing on the inside of that fork blade. The wheel turns freely but the wheel seems to favor that one side and the rim sorta rubs on the brake shoe on that side. The wheel is true so I am guessing the fork blade or blades have to be moved a bit. How do I do this so the wheel is centered between the blades? I don't have access to a special shop with special tools right now. How would this be fixed? Thanks for the help.

Do you have any idea what your fork's made out of? I wouldn't mess with a carbon or aluminum fork at all and if a steel fork is more than a few of millimeters our of alignment I don't like to mess with them. Forks are cheap. dental work is expensive.

The fork is steel, it's an old Raleigh Sports from the 70s. The mis alignment is fairly small. The wheel doesn't rub on the fork at all but it is visibly off center by a little bit. I would say it's off by maybe 1/8-1/4 inch if that. The issue is that it pulls a little to the side and that the rim just touchs the pad on that side and it adds friction to ride. I'd like to center it up using a basic method if at all possible.
The other thing is that the fork for this is almost impossible to find these days. It's the adult 23 inch frame sports in Bronze Green. I haven't located another bronze green sports fork that will fit it so I really want to do it with this original one.

A look at the blades themselves revealed they weren't bent back or the like but that the little prongs at the ends of the blades bent somewhat. I used the wrench to pry them back into center. It took awhile since I was doing this by eye and I missed center a couple of times but after a couple tries I think I got it.

It's your life... buy a new fork.

Better-than-average bike shops will have a tool for aligning fork drop outs. It looks kind of like two mushrooms that screw into the dropouts. It has long stems that provide the leverage necessary for aligning the drop outs.
