Here's my Left Turn "wobble" Fix!

[DickB]

Do you have left turn only “wobble”?

The “wobble” on turns is the Stability Control System operating. From the Operator’s Guide: “A Stability Control System (SCS) is designed to limit the power driving the rear tire and to brake individual wheels, which reduces the risk of losing control of the vehicle or rolling over.”

On my 2019 Rally this was kicking in (early) on hard left turns only. It never kicked in on right turns no matter how aggressively I cornered. I never got a fault or code.

Installing the Ryker Steering Update Kit PN 219800513 as called out in this service bulletin fixed it:

The kit contains new bearings, but also two additional parts – a spring washer and a spacer – that have been added to 2022 and newer models. I confirmed with Can Am that they will cover this update kit under warranty, but if out of warranty it is not covered. I of course was out of warranty, so I installed it myself. Installation was not particularly hard, but you do have to remove several unrelated parts to gain access to some bolts. The instructions with the kit are very thorough with lots of detailed drawings:

A SAS (Steering Angle Sensor) reset and yaw sensor reset are last steps in the installation. This pushed me to get a BUDS2 system. I prefer to do my own maintenance when possible, so this will come in handy. I also used it on my Sea Doo Spark to reset a “Maintenance Required” message.

Back story: I did not become aware of this problem until several months after I bought my Rally used with about 2500 miles on it. As I became more comfortable with the ride and got more aggressive in corners, the problem became evident. I took it to a local dealer. The technician said everything was fine, sensors checked out, and he detected no problem. I suspect he simply did not push hard enough in corners. $170 thrown away. (I should have gotten the BUDS sooner.) I described the service bulletin to the service writer, but he was a bit smug and dismissed it. Sometime later I decided to apply the update kit myself. Problem solved.
