1) Prepare your mower:
Disconnect the spark plug and remove the gas cap to relieve pressure.
Tilt the mower, making sure the carburetor and air filter are facing up to prevent fuel or oil leaks.
If your mower has a blade brake, use it to prevent the blade from turning.
2) Remove the wheel:
Find the wheel you want to work on.
Use a socket wrench to loosen and remove the nuts or bolts that secure the wheel.
Carefully pull the wheel off the axle.
3) Access the bearing:
The bearing assembly may be secured by a retaining clip, dust cover, or washer. Use pliers or a screwdriver to remove these parts.
Some mowers have sealed bearings that cannot be repaired. If this is the case, you will need to replace the entire wheel assembly.

If the bearing is pressed into the hub, you will need to carefully tap it out using a hammer and a punch or a punch. Tap around the bearing, tapping evenly to avoid damaging the hub.
For bearings that have slipped onto the axle, gently pull it out.
5) Clean and inspect:
Clean the hub and axle thoroughly with a rag or paper towel.
Inspect the hub and axle for signs of damage or wear. If you find any cracks or bends, it is best to replace the entire wheel assembly.
6) Install the new bearing:
Apply a thin layer of grease to the new bearing.
Carefully press or slide the new bearing into place. Make sure they are fully seated and aligned correctly.
Reinstall any retaining clips, dust caps, or washers.
7) Reassemble the wheel:
Slide the wheel back onto the axle.
Tighten the nut or bolt by hand, then tighten it securely using a socket wrench.
Do not overtighten as this may damage the bearing or wheel
8) Repeat for other wheels:
Repeat this process for other wheels of the mower if needed.
9) Test the mower:
Reconnect the spark plug and refill the tank.
Start the mower and listen for any unusual noises.
Push the mower to ensure the wheel rotates freely and smoothly.
