KNOLET Front Wheel Hub Bearing Assembly Pair for Toyota Prius 2004-2009 1.5L — 5-Lug, OEM-Style Durable Steel

If your Prius shows wheel rumble, steering vibration, or uneven tire wear, worn hub bearings are often the cause. This KNOLET pair (front left and right) replaces part references 4351047010 / 4351047011 / 4351047012 and is manufactured to OEM-style dimensions using hardened, forged carbon steel for long service life. The assemblies are designed for quick installation, improved durability, and reduced noise compared with tired original parts.

How will these hub assemblies affect driving feel and noise?

New KNOLET hubs reduce play and dragging that cause humming, growling, or steering shimmy. Expect crisper steering response and quieter rolling at highway speeds once properly installed and torqued to spec.

• Precision-machined bearing surfaces for lower friction and consistent rotation.
• Premium seals keep grease in and contaminants out to prevent premature failure.
• Impact-tested construction for stable performance over bumps and potholes.
• Protective coating to resist moisture and corrosion in wet climates.
