How does replacing the knuckle and hub assembly help vehicle performance?

Installing a new knuckle with an integrated hub bearing can resolve symptoms caused by worn or damaged components. Because the hub and bearing come pre-assembled, you eliminate the need for pressing operations and reduce installation time compared with replacing individual parts.

• Reduces steering pull and uneven tire wear by restoring correct wheel alignment
• Eliminates vibration and wobble from worn bearings
• Improves braking stability by ensuring the wheel is held securely

What are the part specifications and what comes in the box?

Each unit is brand new and constructed from steel for strength and longevity. The assemblies arrive loaded and ready for installation; no additional hubs or bearings are required. Axles are not included and should be reused from your vehicle or replaced separately if needed.

• Condition: Brand new, steel construction
• Included: Loaded knuckle, hub, and bearing (axle excluded)
• Reference numbers: 698-477, 698-476, LK034, LK033, 698477, 698476, 4778202210, 4778102210
• Warranty: 1-year limited guarantee

How difficult is installation and what should I prepare?

Installation requires basic suspension and wheel bearing experience plus standard shop tools. Because these are complete, preloaded assemblies, the process is simpler than pressing a new bearing into an existing knuckle, but wheel alignment and torque checks are still necessary after installation.

• Recommended: wheel alignment after installation
• Tools typically needed: jack and stands, torque wrench, ratchets, possibly a ball-joint separator
• Reuse or replace axle/CV shaft depending on condition (axle not included)
