I believe that I've fallen victim to the dreaded u-joint failure. I have a 05 1300 with 85,000 km ( 50,000 miles give or take a few ). I've been reading thru these posts and have decided to dive in head first and see it I can't fix this thing on my own. I was reading some of Curt's post and he pretty much described exactly what I've been experiencing , strange noises , odd vibrations etc . I too started by changing wheel and flange bearings thinking that they were the culprits . No such luck . I have since isolated the noise to what I believe to be the u-joint. So here I stand , armed with my home made swing arm tool and all the knowledge that I could suck up from this site and the Good Book ( Honda Service Manual ). Wish me luck folks . I'm going in . If you don't hear from me again it will be because I tore it all apart , found out that it wasn't the u-joint and decided to hang myself in the garage.
