How to Replace CV Boots on an ATV or Side-by-Side

The CV boots on ATVs and UTVs can be easily damaged by an assortment of trail and track debris such as rocks and tree stumps.

Unless CV boots are replaced when they’re damaged or worn, dirt will get into the CV joints and wreck them in no time. Follow the step-by-step guide below and watch our ATV/UTV CV boot replacement video above to get this job done. 

NOTE: We used Polaris Ranger 800 parts, but the process will be almost identical for CV joints on all makes and models of ATV and side-by-side.

PRO TIP: We recommend you purchase a CV boot kit rather than individual parts. The kits are cheaper and include the CV boot, clamps and grease you’ll need. Find the CV boot kits for your machine by selecting its make, year and model.

Removing ATV or Side-By-Side CV Boots

PRO TIP: For this step-by-step guide, we removed the driveshaft from the vehicle. However, you can replace the CV boots with the driveshaft still attached to the machine.

Step 1. Remove the CV boot retaining clamps using a side jaw pincher tool

NOTE: Even if your ATV or UTV has reusable clamps, you can discard them when using a CV boot kit, which includes new clamps.

Step 2. Cut off the old CV boots and discard them, then clean off as much of the old grease from the CV joints as possible.

Step 3. Position a drift punch against the innermost part of the outer CV joint, and carefully tap the CV joint off the driveshaft splines.

1. Inner CV boot

2. Inner CV boot small clamp

3. Outer CV boot small clamp

Step 6. Pack the CV joints and the new CV boots with the grease included in the CV boot kits.

Step 7. Slide the CV boots over the CV joints so the lip of each boot slots into the channel in each CV joint.

PRO TIP: Make sure the lip of the CV boot and the channel in the CV joint are both clean and free of grease, because you want a tight seal. Any grease will prevent a seal, and can result in the boot slipping off the CV joint.

Step 8. Position each of the CV boot clamps over the CV boot, secure each clamp using a CV joint clamp tool and you’re done.
