Identifying the Problem: Common Problems with Your 2008 Honda Accord Rear Wheel Bearing

Before you grab your wrenches, it’s crucial to confirm that your 2008 Honda Accord rear wheel bearing is indeed the culprit. Misdiagnosis can lead to wasted time and money. Here are the tell-tale signs to look out for:

The Dreaded Hum and Grind

Consistent Hum: This is the most common symptom. It often starts as a low growl or hum that increases in volume and pitch with vehicle speed.
Changing Sounds: The noise might change when you steer the car. For example, if you turn left and the noise gets louder, it often indicates a failing right rear bearing (as weight shifts to that side).
Grinding Sensation: As the bearing deteriorates further, you might feel a grinding or rumbling sensation through the floorboard or steering wheel. This is a sign of severe wear.

Loose Play and Vibration

Wobbly Wheel: With the car safely jacked up and supported, try to wiggle the wheel at the 12 and 6 o’clock positions, then at 3 and 9 o’clock. Any noticeable play or clunking indicates a worn bearing.
Vibration: You might feel vibrations, particularly at higher speeds, that aren’t related to tire balance issues.

Uneven Tire Wear

Feathering or Cupping: A bad bearing can cause the wheel to wobble, leading to irregular tire wear patterns like feathering (one side of the tread block is higher than the other) or cupping (scalloped dips around the tire’s circumference).

If you’re experiencing any of these issues, it’s time to consider a replacement. Ignoring a failing bearing can lead to catastrophic failure, loss of control, and further damage to your suspension and brake components.

Step-by-Step Guide: How to Replace Your 2008 Honda Accord Rear Wheel Bearing

Ready to get your hands dirty? This comprehensive 2008 Honda Accord rear wheel bearing guide will walk you through each step. Remember, safety is paramount!

Safety First: Pre-Work Setup

Park on a Level Surface: Ensure your car is on firm, level ground.
Engage Parking Brake: Apply the parking brake firmly.
Chock Front Wheels: Place wheel chocks in front of and behind the front wheels to prevent any movement.
Loosen Lug Nuts: While the car is still on the ground, use your lug nut wrench or breaker bar to slightly loosen the lug nuts on the wheel you’ll be working on. Don’t remove them completely yet.
Jack Up the Car: Place your floor jack under a strong, designated jacking point near the rear wheel. Lift the car until the wheel is off the ground.
Secure with Jack Stands: Place jack stands under the vehicle’s frame or designated support points. Lower the car onto the jack stands, ensuring it’s stable.
Remove Wheel: Finish unscrewing the lug nuts and carefully remove the wheel. Store it safely out of the way.

Disassembly: Getting to the Hub

Remove Brake Caliper:
- Locate the two guide pin bolts on the back of the brake caliper (usually 12mm or 14mm).
- Use your socket wrench to remove these bolts.
- Carefully slide the caliper off the rotor. Do NOT let it hang by the brake hose, as this can damage the hose. Use a bungee cord or wire to suspend it securely from the coil spring or another sturdy suspension component.
Remove Caliper Mounting Bracket:
- The caliper bracket is typically held by two larger bolts (often 17mm or 19mm) that secure it to the trailing arm.
- Remove these bolts and set the bracket aside.
Remove Brake Rotor:
- The rotor may be held on by two small Phillips head screws. Remove these.
- If the rotor is stuck due to rust, you can try tapping its face with a rubber mallet or using the threaded holes (if present) to push it off with bolts.
Access the Axle Nut:
- Remove the dust cap in the center of the hub. You might need a flathead screwdriver to pry it off.
- You’ll see a large axle nut, often staked in place. Use a chisel and hammer to unstake the nut before attempting to loosen it.
- Using your large socket (32mm or 36mm, depending on your Accord’s specific axle nut size) and a breaker bar, loosen and remove the axle nut. This nut is often very tight.

Removing the Old Bearing Assembly

Separate the Axle Shaft:
- Gently push the axle shaft inward to disengage it from the old hub assembly. It should slide freely once the axle nut is removed.
Remove Hub Assembly Bolts:
- The rear wheel bearing (hub assembly) is typically held to the knuckle by four bolts from the backside. These are usually 14mm or 17mm.
- You’ll need to reach around the back of the knuckle to access these. They can be stubborn due to rust. Use penetrating oil and a good breaker bar if necessary.
- Once all four bolts are removed, the old hub assembly should be free.
Stubborn Hub?
- If the hub is seized due to rust, you might need to use a hammer to tap it from the backside, or a hub puller tool. Be careful not to damage the axle shaft or other components.

Installing the New Bearing Assembly

Clean the Mounting Surface:
- Before installing the new bearing, thoroughly clean the mating surface on the knuckle where the new hub assembly will sit. Use a wire brush to remove any rust or debris. This ensures a proper fit and prevents future issues.
Install New Hub Assembly:
- Carefully align the new hub assembly with the bolt holes on the knuckle.
- Insert the four mounting bolts from the backside and hand-tighten them.
- Torque the Hub Bolts: Using your torque wrench, tighten these four bolts to the manufacturer’s specified torque (check your service manual, typically around 50-60 ft-lbs). Tighten them in a cross-pattern to ensure even seating.
Reinstall Axle Shaft:
- Slide the axle shaft back through the center of the new hub assembly.
- Thread on the new axle nut.
- Important: Do not fully torque the axle nut yet.

Reassembly and Final Checks

Reinstall Brake Rotor:
- Place the brake rotor back onto the hub. Secure it with the two small Phillips head screws (if applicable).
Reinstall Caliper Mounting Bracket:
- Attach the caliper mounting bracket to the knuckle using its two large bolts.
- Torque the Bracket Bolts: Tighten these bolts to factory specifications (often around 80-90 ft-lbs).
Reinstall Brake Caliper:
- Carefully slide the caliper back over the rotor and onto the bracket’s guide pins. If the pads are too tight, you may need to compress the piston slightly using a C-clamp or caliper tool.
- Reinstall the two guide pin bolts.
- Torque the Guide Pin Bolts: Tighten these to factory specifications (usually around 20-25 ft-lbs).
Final Axle Nut Torque:
- With the vehicle still on jack stands, you need to fully torque the axle nut. This nut requires significant torque (often 180-200 ft-lbs). You may need someone to depress the brake pedal to prevent the hub from spinning while you torque the nut.
- Stake the Axle Nut: Once torqued, use a chisel and hammer to stake the collar of the axle nut into the groove on the axle shaft. This prevents it from backing off.
Reinstall Dust Cap:
- Tap the dust cap back into place over the axle nut.
Reinstall Wheel:
- Mount the wheel back onto the hub. Hand-tighten the lug nuts.
- Lower the car off the jack stands.
- Final Lug Nut Torque: With the car on the ground, torque the lug nuts in a star pattern to factory specifications (usually 80 ft-lbs).
Test Drive:
- Take your Accord for a short, careful test drive. Listen for any unusual noises and check for proper braking. The humming sound should be gone!

Pro Tips and Best Practices for 2008 Honda Accord Rear Wheel Bearing Care

Replacing a wheel bearing is a significant repair, and applying some pro tips can make the job easier and ensure longevity. These 2008 Honda Accord rear wheel bearing tips come from years of experience.

Torque Specifications Matter

We’ve said it before, but it bears repeating: use a torque wrench! Overtightening bolts can strip threads or distort components, leading to premature failure. Undertightening can cause parts to loosen, creating dangerous conditions. Always refer to your Honda service manual for precise torque values for every fastener.

Brake System Considerations

Brake Fluid: When compressing the caliper piston, some brake fluid might be pushed back into the master cylinder. Keep an eye on the fluid level and ensure it doesn’t overflow.
Bleeding Brakes: If you disconnected a brake line (which isn’t usually necessary for a bearing replacement), you absolutely must bleed the brake system afterwards to remove any air.
Cleanliness: Keep brake components clean and free of grease. Use brake cleaner only.

When to Call a Pro

While this is a DIY-friendly job, there are times when it’s best to call in a professional:

Seized Bolts: If you encounter bolts that simply won’t budge, even with penetrating oil and a breaker bar, you risk rounding them off or breaking them. A professional has specialized tools (like impact wrenches or heat) to handle these.
Lack of Proper Tools: If you don’t have a torque wrench, large sockets, or adequate jack stands, it’s safer to let a shop handle it.
Uncertainty: If you’re unsure about any step, or if something doesn’t feel right, don’t guess. A professional diagnosis or repair can prevent costly mistakes.
Damage to Other Components: If you accidentally damage an ABS wire, brake line, or axle boot during the process, it might be better to have a shop correct it.

Sometimes, the cost of specialized tools or potential damage outweighs the savings of a DIY repair. Knowing your limits is part of being a smart mechanic.
