Hey guys! Ever notice that your LC135 isn't running as smoothly as it used to? Maybe you're hearing some weird noises coming from the back wheel? It could be a sign that your rear wheel bearings are on their way out. Don't worry, it happens! Replacing them might sound intimidating, but with a bit of patience and the right tools, you can totally do it yourself. This guide will walk you through the whole process of replacing your LC135's rear wheel bearings, making sure your bike is back to its smooth-riding self in no time. So, grab your tools, and let's get started!

Symptoms of Worn Rear Wheel Bearings

Before we dive into the replacement process, let's make sure those strange noises are actually coming from the wheel bearings. Identifying the problem early can save you from further damage and more expensive repairs down the road. Here's what to look (and listen) for:

• Unusual Noises: This is often the first sign. You might hear a grinding, rumbling, or clicking sound coming from the rear wheel, especially when you're riding at higher speeds. The noise might get louder when you lean into turns.
• Wheel Play: Put your bike on a center stand or use a paddock stand to lift the rear wheel off the ground. Grab the wheel at the top and bottom and try to rock it back and forth. If you feel any play or movement, that's a telltale sign of worn bearings. There should be absolutely no play in a healthy wheel bearing.
• Rough Wheel Rotation: Spin the rear wheel by hand. It should spin freely and smoothly. If you feel any resistance, roughness, or hear any grinding noises, the bearings are likely damaged.
• Vibration: You might feel unusual vibrations through the seat or handlebars, especially at higher speeds. This can be a sign of several issues, but worn wheel bearings are a common culprit.
• Chain Issues: While not a direct symptom, worn wheel bearings can sometimes cause the chain to wear unevenly or jump off the sprocket. This is because the wheel isn't spinning straight and true.

If you're experiencing one or more of these symptoms, it's a good idea to inspect your rear wheel bearings. Ignoring these signs can lead to a complete bearing failure, which can be dangerous and cause damage to other parts of your bike. So, pay attention to your bike, and don't ignore those weird noises!

Tools and Materials You'll Need

Alright, so you've confirmed that your rear wheel bearings are indeed the problem. Now it's time to gather your tools and materials. Having everything ready before you start will make the job much smoother and less frustrating. Here's a list of what you'll need:

• New Wheel Bearings: Make sure you get the correct size and type of bearings for your LC135. Check your bike's manual or consult with a local motorcycle shop to ensure you're getting the right ones. It's always a good idea to replace both bearings at the same time, even if only one seems bad.
• Sockets and Wrenches: You'll need a variety of sockets and wrenches to remove the rear wheel, axle, and other components. Make sure you have the correct sizes for your bike. A socket set with a range of sizes is highly recommended.
• Bearing Puller: This tool is essential for removing the old bearings without damaging the wheel hub. There are various types of bearing pullers available, so choose one that's suitable for motorcycle wheel bearings.
• Bearing Press or Driver: This is used to install the new bearings into the wheel hub. A bearing press is the ideal tool, but a bearing driver set with the correct size adapters can also work.
• Hammer: You might need a hammer to gently tap the bearing driver or to help loosen stubborn components. Use a rubber mallet to avoid damaging any parts.
• Punch or Drift: A punch or drift can be used to help drive out the old bearings or to seat the new bearings properly.
• Grease: You'll need some high-quality grease to lubricate the new bearings before installation. This will help them last longer and reduce friction.
• Torque Wrench: A torque wrench is crucial for tightening the axle nut and other components to the correct specifications. This will ensure that everything is properly secured and prevent damage.
• Gloves: Protect your hands from grease and dirt with a pair of gloves.
• Shop Rags: Keep some shop rags handy to wipe up any spills and keep your work area clean.
• Motorcycle Stand: A motorcycle stand or paddock stand is essential for lifting the rear wheel off the ground.

Having all these tools and materials on hand will make the rear wheel bearing replacement process much easier and more efficient. So, take the time to gather everything before you start, and you'll be well on your way to getting your bike back on the road.

Step-by-Step Replacement Guide

Okay, you've got your tools, you've got your bearings, and you're ready to get your hands dirty! Let's dive into the step-by-step process of replacing those worn-out rear wheel bearings on your LC135. Remember to take your time, be patient, and don't force anything. If you're unsure about any step, consult your bike's manual or seek help from a qualified mechanic.

1. Prepare the Bike: Start by placing your LC135 on a center stand or using a paddock stand to lift the rear wheel off the ground. Make sure the bike is stable and secure before you start working.
2. Remove the Rear Wheel: Loosen the axle nut using the appropriate socket and wrench. Then, remove the brake caliper (being careful not to damage the brake lines) and any other components that are attached to the rear wheel. Finally, pull the axle out and remove the rear wheel from the bike.
3. Remove the Old Bearings: This is where the bearing puller comes in handy. Follow the instructions for your specific bearing puller to remove the old bearings from the wheel hub. If you don't have a bearing puller, you can try using a punch and hammer to carefully drive the bearings out from the opposite side. Be extremely careful not to damage the wheel hub.
4. Clean the Wheel Hub: Once the old bearings are out, thoroughly clean the wheel hub with a clean rag and some degreaser. Remove any dirt, grease, or debris that may be present. This will ensure that the new bearings seat properly.
5. Install the New Bearings: Apply a generous amount of grease to the new bearings. Then, use a bearing press or bearing driver to carefully press the new bearings into the wheel hub. Make sure the bearings are seated fully and squarely in the hub. If you're using a bearing driver, tap it gently with a hammer until the bearing is fully seated. Again, be careful not to damage the wheel hub.
6. Reinstall the Rear Wheel: Now it's time to put everything back together. Slide the rear wheel back into place, insert the axle, and tighten the axle nut to the correct torque specification using a torque wrench. Reinstall the brake caliper and any other components that you removed earlier.
7. Check for Proper Function: Once everything is reassembled, spin the rear wheel by hand to make sure it rotates freely and smoothly. Check for any play or movement in the wheel. If everything seems okay, take the bike for a short test ride to ensure that the new bearings are working properly.

Important Note: Always refer to your LC135's service manual for specific torque specifications and any other relevant information. Improper installation can lead to bearing failure and potential damage to your bike.

Tips and Tricks for a Smooth Replacement

Replacing rear wheel bearings isn't rocket science, but a few tips and tricks can make the job even easier and ensure a successful outcome. Here are some things to keep in mind:

• Heat is Your Friend: If the old bearings are particularly stubborn, try applying some heat to the wheel hub using a heat gun or hairdryer. This will help expand the metal and make it easier to remove the bearings. Be careful not to overheat the hub, and always wear gloves to protect your hands.
• Freeze the New Bearings: Conversely, freezing the new bearings for a few hours before installation can help them shrink slightly, making them easier to press into the wheel hub. Just make sure to let them warm up slightly before installation to prevent condensation.
• Use the Right Tools: Investing in quality tools, such as a bearing puller and bearing press, will make the job much easier and reduce the risk of damaging the wheel hub. Avoid using makeshift tools or methods, as they can often cause more harm than good.
• Don't Over-Tighten: When tightening the axle nut and other components, always use a torque wrench and follow the manufacturer's specifications. Over-tightening can damage the bearings, threads, or other parts.
• Grease is Key: Don't skimp on the grease! Applying a generous amount of high-quality grease to the new bearings will help them last longer and reduce friction. Use a grease that's specifically designed for wheel bearings.
• Take Your Time: Rushing the job can lead to mistakes and potential damage. Take your time, be patient, and double-check your work at each step. If you're unsure about anything, consult your bike's manual or seek help from a qualified mechanic.

By following these tips and tricks, you can make the rear wheel bearing replacement process smoother, safer, and more efficient. So, take your time, use the right tools, and don't be afraid to ask for help if you need it.
