As Lamont, and others have pointed out (mostly in other threads) ... some 2013's suffered from alignment issues AND ball joint problems and some only the ball joint problems. Sounds to me as if your ryde was one of the few that suffered from BOTH issues (unfortunately ... but, sometimes :cus: happens and it just royally p**ses you off). Also, as Scotty (I think) pointed out very early in the "twitching" threads, this is an indication that toe in is off; Lamont, just above has noted that the new alignment procedure is complicated. So, if your dealer has not actually followed all the protocols for alignment and replacement of the ball joints, then IMHO your real difficulty is with the dealer.
The reason I say "take heart" .... according to your recent post "BRP R&D was going to setup a spyder for MY weight TOMORROW and set the tow and alignment" -- that sounds as if you will get a machine that is CORRECT IN EVERY WAY (you know it will have good ball joints and proper alignment). So .... I know you are frustrated beyond words ...but, please don't give up just yet. Best Regards .... Ann
