Root Causes of CV Boot Damage
Both axle sets on the 2005 Honda Rincon 650 4X4 carry CV boots, and keeping all four in serviceable condition is part of maintaining the machine’s reliability for work use. The front axle boots see the most demanding articulation—the outer boot at maximum steering lock under load reaches the extreme of its flex range—while the rear boots handle the sustained torque and repetitive cycling of the driven rear axle during hauling and plowing work. A utility ATV used consistently in these conditions wears its boots faster than one used only for trail riding, because the work load cycles are sustained and repetitive rather than intermittent.
UV radiation degrades all four boot positions simultaneously between rides. The rubber compound stiffens and eventually cracks at the fold lines where the boot flexes most, and the timeline for this degradation is driven by sun exposure, temperature cycles, and the age of the rubber rather than by operating hours. A thorough boot inspection at the start of each working season on the Rincon 650 4X4 helps catch degradation before it opens into a tear that costs a joint replacement rather than a boot kit.
As a 4WD machine, the Rincon 650 4X4 drives both the front and rear wheels. CV boots are present at both axle sets—two boots at the front and two at the rear. All four positions should be inspected and serviced together whenever one is found to be damaged.
Diagnosing Boot Failure at Either End
Boot failures on the 2005 Honda Rincon 650 4X4 produce location-specific evidence. Grease on the inside of the front wheel, the front rotor, or the front caliper points to a front axle boot. Grease on the inside of the rear wheel or rear brake components points to a rear boot. CV grease is thick and dark—it accumulates distinctively on surfaces rather than blending with grime—and finding it near any axle on the Rincon 650 4X4 is cause for an immediate inspection before returning the machine to work.
On the Rincon 650 4X4, front CV boot failures typically produce a clicking or popping sound during slow-speed power turns at or near full lock. Rear boot failures tend to show up as clicking or clunking during acceleration under load. Raise the machine on jack stands, remove the wheel on the affected side, and examine each boot by hand while rotating the axle. Look and feel for tears, cracks, stiff fold areas, and clamp gaps. Any of these findings, alongside grease deposits, means the joint needs evaluation—a boot that has been torn long enough to cause noise has likely allowed contamination to reach the joint surfaces.
On the Rincon 650 4X4, all four CV boot positions—front inner, front outer, rear inner, rear outer—use the same inspection and replacement process. Check all four when servicing any one of them.
Tools, Parts, and Preparation
Stage the following before working on the 2005 Honda Rincon 650 4X4: floor jack and jack stands; axle nut socket in the size correct for the Rincon 650 4X4; torque wrench; snap-ring pliers; boot clamp tool; and shop rags. A separate CV boot kit—boot, two clamps, and CV grease—is needed for each axle position being serviced. CV grease is engineered for CV joint contact conditions and is not substitutable with off-the-shelf lubricants. The molybdenum compound in CV grease is what provides the film strength the joint needs under load.

Taking the Axle Apart
Get the 2005 Honda Rincon 650 4X4 on jack stands and remove the wheel from the side being worked. Remove the cotter pin and axle nut. Push the axle spline inward to free it from the hub, using a hub puller if the Rincon 650 4X4 requires it. Release the snap ring at the differential inboard end and pull the axle free. Set it on a clean surface, cut the old clamp bands, and slide the torn boot free. For the front axle on the Rincon 650 4X4, check whether tie rod or steering component clearance is needed before pulling the axle. Clean the clamp groove areas on both the shaft and housing before fitting the replacement boot.
Assessing the Joint After Boot Removal
Clean the CV joint on the 2005 Honda Rincon 650 4X4 after boot removal and work it through its full designed articulation. Smooth motion throughout indicates a serviceable joint. Roughness or catching at any angle points to ball or race wear. Test for play by stabilizing the shaft and pushing the outer housing side to side and along the shaft axis. A healthy joint on the Rincon 650 4X4 is firm in its articulation range with no rattle or looseness outside it. Play or clunking in non-articulating directions means the axle assembly needs replacement—sealing a worn joint behind a new boot produces a short-lived repair.
Grease and Reassembly
Before repacking the joint on the 2005 Honda Rincon 650 4X4, remove all old grease and contamination from every internal surface. Thread the replacement boot onto the shaft before Reconnecting the joint end. Pack the CV grease from the Rincon 650 4X4’s kit into the joint completely, rotating the housing for even distribution. Use the full kit quantity. Position the boot with both ends seated in the clamp grooves, crimp both clamps to full engagement, and tug each to confirm it’s locked.

Final Steps and Test Ride
Seat the inboard axle end in the differential on the 2005 Honda Rincon 650 4X4 until the snap ring clicks into place—a pull test should show it locked. Guide the outboard spline into the hub, install and torque the axle nut to the Rincon 650 4X4’s specification. Secure with a new cotter pin or re-stake as appropriate. Reinstall the wheel and torque the lug nuts. Lower the Rincon 650 4X4 and steer through lock-to-lock range to verify the boot clears all surrounding components. A short test ride completes the service. MotoSport.com carries CV boot kits and axle assemblies for this ATV.
