Identifying the Need for Replacement

Before you even think about wrenching on your bike, let's make sure a rear wheel bearing replacement is truly necessary. Several telltale signs indicate a worn or damaged bearing. Keep an ear out for unusual noises. A common symptom is a grinding, rumbling, or whining sound emanating from the rear wheel area, especially noticeable at higher speeds. These noises are often exacerbated when cornering or leaning into turns. Another way to diagnose a bad bearing is by physically inspecting the wheel. Put your bike on a center stand or paddock stand, allowing the rear wheel to spin freely. Grab the wheel at the 3 and 9 o'clock positions and try to wiggle it from side to side. Any noticeable play or looseness suggests bearing failure. Similarly, try the same test at the 12 and 6 o'clock positions. A healthy wheel should feel solid and stable, with no excessive movement. Don't ignore these warning signs! Riding with a faulty wheel bearing can be dangerous, leading to instability, reduced handling, and potentially a complete wheel failure. Replacing a worn bearing promptly ensures your safety and prevents further damage to other components, such as the wheel hub or axle. So, listen to your bike, pay attention to its behavior, and don't hesitate to investigate any unusual symptoms. Regular maintenance and inspections are key to keeping your LC135 running smoothly and safely for years to come. Ignoring these signs can lead to more expensive repairs down the road, so it's always best to address potential issues early on.

With all these tools and materials gathered, you'll be well-prepared to tackle the rear wheel bearing replacement on your LC135.

Step-by-Step Replacement Guide

Okay, guys, with your tools and materials ready, let's get down to the nitty-gritty of replacing that rear wheel bearing on your LC135! Remember to work in a clean, well-lit area, and take your time to avoid mistakes. First, loosen the axle nut while the rear wheel is still on the ground. This will prevent the wheel from spinning when you try to loosen the nut later. Next, lift the rear of the bike using a center stand or paddock stand, ensuring the rear wheel is completely off the ground. Remove the axle nut and carefully slide the axle out of the wheel hub. You may need to use a rubber mallet to gently tap the axle if it's stuck. Once the axle is removed, carefully detach the rear wheel from the motorcycle. Be mindful of the brake caliper and any other components that might be attached to the wheel. With the wheel removed, locate the circlips that retain the bearing in the hub. Use circlip pliers to carefully remove these circlips. Now comes the tricky part: removing the old bearing. Using your bearing puller or blind hole puller set, carefully extract the old bearing from the hub. Follow the instructions provided with your bearing puller for the best results. If you don't have a bearing puller, you can try using a hammer and punch to gently tap the bearing out from the opposite side. However, be extremely careful not to damage the hub. Before installing the new bearing, thoroughly clean the wheel hub with a clean cloth and some degreaser. Inspect the hub for any damage or wear, and address any issues before proceeding. Apply a generous amount of grease to the inside of the hub and the outer surface of the new bearing. This will help ensure smooth installation and prevent premature wear. Using your bearing press or driver set, carefully press the new bearing into the hub. Make sure the bearing is seated straight and evenly, and avoid applying excessive force. If you don't have a bearing press, you can try using a hammer and punch to gently tap the bearing into place. However, be extremely careful not to damage the bearing or hub. Once the new bearing is installed, reinstall the circlips to secure it in place. Ensure the circlips are properly seated in their grooves. Reinstall the rear wheel onto the motorcycle, carefully aligning the brake caliper and any other components. Slide the axle back through the hub and tighten the axle nut to the manufacturer's specified torque using a torque wrench. Double-check that everything is properly aligned and secured before lowering the bike. Finally, lower the bike and test the rear wheel for any play or looseness. The wheel should spin freely and smoothly, with no unusual noises or vibrations. If everything checks out, you've successfully replaced the rear wheel bearing on your LC135! Remember to take it for a short test ride to ensure everything is working properly before embarking on any long journeys.
