How to Inspect and Replace Wheel Bearings on a 1987 Honda CR500
Shop parts for a 1987 Honda CR500 Dirt Bike.Why wheel bearings matter on a 1987 Honda CR500
On the 1987 Honda CR500, wheel bearings let the front and rear wheels spin smoothly while holding precise alignment under braking, cornering, and hard landings. Proper bearings reduce drivetrain drag, keep handling predictable, and prevent wobble or uneven tire wear. The CR500 is a performance motocross platform subjected to jumps, hard landings, and aggressive cornering all of which accelerate bearing stress compared with trail riding.
Common symptoms of worn bearings
- Side-to-side wheel play when the bike is on a stand
- Grinding, rough rotation, or a gritty feel when spinning the wheel
- Clicking or knocking sounds that change with wheel rotation
- Resistance or drag while the wheel spins freely
- Vague steering, uneven tire wear, or a feeling of looseness under braking
Quick inspection checklist before you remove a wheel
Use a solid stand that lifts the CR500 so the wheel can spin freely. Perform these checks with basic hand tools and visual inspection.
- Grip the tire at 3 and 9 o'clock and rock laterally to detect play. Any noticeable movement usually means bearings, spacers, or axle seating issues.
- Spin the wheel and listen/feel for roughness, grinding, or clicking. Compare to the opposite wheel if unsure.
- Inspect wheel seals for tears, missing lips, or compressed rubber that could allow contamination.
- Look inside the hub for rust, mud, or missing grease. Pressure washing, water crossings, and mud riding commonly accelerate bearing failure on a CR500.
Tools and supplies you may need
- Metric sockets, wrenches & hex keys
- Wheel stand or center stand
- Bearing driver set or correctly sized sockets
- Soft-faced hammer or machinist's hammer
- Punch or drift for careful removal
- Cleaning solvent, lint-free rags, and light grease
- Replacement sealed cartridge bearings & new wheel seals
Removing the wheel on a 1987 Honda CR500
- Secure the bike on a stand so the wheel clears the ground.
- Loosen brake caliper mounts and remove the caliper from the fork or swingarm; hang it out of the way without stressing the brake line.
- Remove the axle nut and slide the axle out while supporting the wheel to prevent dropping spacers.
- Note the order and orientation of axle spacers and shims take photos or lay parts out in sequence.
Removing old bearings and seals
Work on a clean bench. Start by removing the outer wheel seal with a small puller or gentle prying, taking care not to score the hub bore.
- Use a bearing driver or a socket that contacts only the inner race to drive the bearing out from the opposite side. Drive evenly and avoid cocking the bearing.
- If only a punch is available, support the hub and work methodically from the bearing edge toward the hub center to avoid hub damage.
- Repeat for both bearings on the wheel.
- Clean the hub bore thoroughly and inspect for pitting, corrosion, or ovalization. Minor surface rust can be cleaned, but deep damage means hub replacement.
Installing new sealed bearings
Most wheel bearings for the 1987 Honda CR500 are sealed cartridge bearings pre-packed with grease. They are not serviceable internally.
- Lightly coat the hub bore with a thin film of grease to help the bearing slide in and to deter corrosion.
- Place the bearing squarely into the bore. Use a bearing driver or a socket that contacts the outer race to press the bearing in evenly apply pressure only to the race you are seating to avoid damaging rollers or cages.
- Drive the bearing until it seats fully against the shoulder; repeat for the opposite side.
- Install new seals with even pressure, ensuring sealing lips face out to exclude water and dirt.
Reassembly and final checks
- Reinstall axle spacers in their original orientation. Lightly coat axle shafts & spacer faces with grease to prevent corrosion and help seal engagement with the sealing lips.
- Slide the axle through, torque the nut to a firm setting that seats components without preloading the bearings the wheel should spin freely with no play.
- Reinstall the brake caliper and check rotor alignment. Spin the wheel and listen for smooth rotation; check for lateral play again.
- Test ride and pay attention to handling, braking feel, and any new noises.
Front vs rear bearing considerations
The rear bearings on a CR500 endure higher loads from drivetrain torque, chain lash, and harsher landings. Expect rear bearings to wear faster. When replacing one bearing, inspect the opposite wheel bearings often fail in pairs or as a result of the same riding conditions.
Sealed bearing guidance & greasing points
- Sealed bearings should not be opened, oiled, or repacked. If contamination or roughness is found, replace the sealed unit.
- Apply a light coat of grease to the axle shaft, axle spacers, and sealing lips of wheel seals to protect against corrosion and aid sealing.
Preventive maintenance for longer bearing life
- Avoid aiming a pressure washer directly at wheel seals high-pressure spray forces water into seals.
- After muddy or wet rides, clean hubs and allow them to dry before storage.
- Check for wheel play periodically and inspect seals for damage; replace seals whenever bearings are serviced.
- Address loose axle hardware, bent spacers, or damaged hub faces immediately to prevent rapid bearing failure.
Final notes
On the 1987 Honda CR500, diligent inspection and careful bearing replacement prevent instability and protect the hub. Use the right tools, replace sealed bearings rather than attempting to service them, and treat the rear wheel as a higher-load component. Regular checks after aggressive motocross use will keep your CR500 turning true and responding at the track.
