Well, I picked up my new to me 2009 gl1800 champion IRS trike on Saturday, rode it home and noticed a thumping on highway. Long story short, I pulled the drive shaft and found the front u joint bad. I called champion trike arizona and they don't have spare driveshafts, all are on backorder and no idea when will come in. He gave me part # of the ujoint, which cannot be serviced...lol. no driveline shops will touch it. So sad she has to sit on lift in garage for an undetermined amount of time. But at least I can get one someday....to the tune of $1200!. Frustrating to have a new ride and not be able to RIDE. does anyone have any ideas on how to repair this driveshaft?
