Why Replace Your LC135 Rear Wheel Bearing?

Okay, first things first, why even bother changing the rear wheel bearing? Your LC135's rear wheel bearing is a crucial component that ensures smooth and efficient wheel rotation. Over time, it can wear out due to various factors like exposure to dirt, water, and general wear and tear. A worn-out bearing can lead to a host of problems, so it’s essential to keep it in good condition. Ignoring a bad bearing can lead to further damage and potential safety hazards, so paying attention to this little part can save you a lot of trouble down the road.

One of the most common signs of a failing rear wheel bearing is unusual noise coming from the rear wheel area. This might sound like a grinding, rumbling, or clicking noise that gets louder as you accelerate. Another telltale sign is excessive play or wobble in the rear wheel. If you notice that your wheel feels loose or wobbly when you try to move it side to side, it's a strong indication that the bearing is worn out. A worn bearing can also cause increased friction, which can affect your bike's performance and fuel efficiency. You might notice that your bike feels sluggish or requires more effort to maintain speed. In severe cases, a failing bearing can even cause the wheel to lock up, which can be extremely dangerous. So, if you notice any of these symptoms, it's crucial to inspect and replace the rear wheel bearing as soon as possible to ensure your safety and the longevity of your bike.

Replacing your LC135's rear wheel bearing is not just about fixing a problem; it's about maintaining the overall health and performance of your bike. A healthy bearing ensures smooth and efficient power transfer from the engine to the wheel, which translates to better acceleration, handling, and fuel economy. Regular maintenance and timely replacement of worn parts can also prevent more serious and costly damage to other components of your bike. For example, a failing bearing can put extra stress on the axle, wheel hub, and even the swingarm, leading to premature wear and potential failure. By addressing the issue promptly, you can avoid these cascading effects and keep your bike running smoothly for longer. Moreover, a well-maintained bike is a safer bike. A worn bearing can compromise your bike's handling and stability, especially at high speeds or during emergency braking. Replacing the bearing ensures that your wheel is properly supported and can handle the stresses of riding, giving you more confidence and control on the road. So, don't underestimate the importance of this small but vital component, and make sure to give it the attention it deserves.

Step-by-Step Guide to Replacing the Bearing

Okay, let's get down to business! Here’s a step-by-step guide to replacing the rear wheel bearing on your LC135. Follow these instructions carefully, and you'll be cruising again in no time.

1. Preparation is Key:
   • Park your LC135 on a level surface and engage the parking brake or use wheel chocks to prevent it from rolling.
   • Gather all the tools and materials you'll need and lay them out within easy reach.
   • Put on your gloves and safety glasses to protect yourself.
2. Remove the Rear Wheel:
   • Loosen the axle nut using the appropriate socket or wrench. It's often a good idea to do this while the wheel is still on the ground to prevent it from spinning.
   • Lift the rear of the bike using a motorcycle jack or stands, ensuring it's stable and secure.
   • Remove the axle nut completely and carefully slide the axle out of the wheel hub. You may need to use a rubber mallet to gently tap it out if it's stuck.
   • Once the axle is removed, carefully remove the rear wheel from the bike.
3. Access the Bearing:
   • With the wheel removed, locate the rear wheel bearing in the hub. It's usually covered by a seal, which you'll need to remove.
   • Use a small screwdriver or pick to carefully pry out the seal, being careful not to damage the surrounding components.
4. Remove the Old Bearing:
   • This is where the bearing puller comes in handy. Follow the instructions that came with your bearing puller to properly attach it to the bearing.
   • Use the puller to gradually and evenly extract the bearing from the hub. If you don't have a bearing puller, you can use a punch and hammer to carefully tap the bearing out from the opposite side. Work your way around the bearing, tapping gently and evenly to avoid damaging the hub.
   • If the bearing is particularly stubborn, you may need to apply some heat to the hub using a heat gun or torch. This will help expand the metal and make it easier to remove the bearing. Be careful not to overheat the hub, and always wear gloves and eye protection when working with heat.
5. Clean the Hub:
   • Once the old bearing is removed, thoroughly clean the inside of the hub to remove any dirt, grease, or debris.
   • Use a clean rag and some degreaser to wipe down the surfaces, ensuring they are clean and dry.
   • Inspect the hub for any signs of damage, such as cracks or excessive wear. If you find any damage, it's essential to address it before installing the new bearing.
6. Install the New Bearing:
   • Before installing the new bearing, apply a thin layer of grease to the inside of the hub. This will help the bearing slide in more easily and prevent corrosion.
   • Align the new bearing with the hub and use a bearing press or driver to gently press it into place. If you don't have a bearing press, you can use a socket that is slightly smaller than the bearing's outer diameter and a hammer to carefully tap it in.
   • Ensure that the bearing is seated straight and flush with the hub. Avoid using excessive force, as this can damage the bearing or the hub.
7. Reinstall the Seal:
   • Once the new bearing is installed, reinstall the seal to protect it from dirt and moisture.
   • Apply a small amount of grease to the seal before pressing it into place.
   • Ensure that the seal is properly seated and flush with the hub.
8. Reinstall the Wheel:
   • Carefully reinstall the rear wheel onto the bike, aligning the hub with the swingarm and brake components.
   • Slide the axle back through the hub and swingarm, ensuring it's properly aligned.
   • Tighten the axle nut to the manufacturer's specified torque using a torque wrench.
9. Final Checks:
   • Before hitting the road, double-check that everything is properly installed and tightened.
   • Spin the rear wheel to ensure it rotates smoothly and freely.
   • Check the brakes to make sure they are functioning correctly.

And there you have it! You've successfully replaced the rear wheel bearing on your LC135. Take it for a short test ride to ensure everything is working as it should be. If you notice any unusual noises or vibrations, stop and recheck your work. Remember, safety is always the top priority!
