I'm in the process of replacing this driveshaft and have been talking with Champion Trikes in Arizona. They said the front U-joint cannot be replaced and they do not sell the straight driveshafts anymore. I was told they updated to collapsible driveshafts for easier removal. They gave me a price of $1200 +30 shipping+3.5% if you use a cc. I'm thinking is there a better and cheaper alternative to replace my driveshaft?
