Polaris Ranger 900 Rear CV Boot Replacement

Always inspect the CV boots on a Polaris UTV as part of your pre-ride checks. A split rear CV boot allows water and dirt into the CV joints, which quickly damages the joints and the driveshaft.

Replacing worn or damaged CV boots now costs a lot less than having to replace the CV joints and driveshaft due to neglect. Watch the video above and follow the steps below to replace the CV boots on a Polaris Ranger 900XP.

  • Use metal snips to cut the bands off.
  • Use a cut-off wheel to cut the bands off.

Step 6. Pull the outer CV boot off the outer CV joint and up toward the center of the driveshaft.
