HELLO ALL!! Thank you so much for all your replies. I think I'm getting close to 10 posts and then i can post pics? (at least i keep getting told i need 10 posts before i can put up pics...?) regardless....i may have found a local repair shop willing to take a look. if not, i'll be moving forward with attempting to repair it myself. The resources you guys provided in this thread appear to be just what i need. i have the hub off the trike and just waiting to be fixed. once i heard back from the repair shop, i'll see about fixing it myself, and then beyond that, hopefully being able to locate the proper replacement. price isn't too much of an issue, this is worth it to me.
THANK YOU AGAIN!! super grateful.
