My current stingray project has an automatic 2 speed kick back hub on it. It shifts and works but is noisy and doesn't want to coast well. Took it to my LBS, he says he needs a special tool to get it apart. I have read you can take these apart from the brake arm side if you can't get that lock nut off. Any one done this? Any tips? He can't help me so I guess I'm going to tackle the job. Never done a 2 speed yet. I have a diagram on the order of parts installed. Almost curious if I can just open it up a bit and get some lube in there. Thanks in advance!
