We’ll help you fix your  problem on your own without expensive shop repair costs.

The basics…

The 4wd system on your Yamaha ATV or Side by Side is operated by a push button switch that sends power to a relay, which in turn sends power to the servo motor, which engages your 2wd, 4wd, and difflock.  It’s easy to troubleshoot and repair these components without spending an arm and a leg.

If you are unfamiliar with the 4wd system, see our troubleshooting page.  It will help you identify, diagnose, and repair your 4wd issues as easy and inexpensive as possible.

Still unsure where to go from here? 

Step 1- See our troubleshooting page to identify your 4wd components and figure what went wrong.
