KNOLET Front Wheel Bearing Hub Assembly Pair 513257 — 5-Lug w/ABS Encoder, Direct-Fit for Toyota/Lexus/Scion

KNOLET 513257 front wheel bearing hub assembly is a direct-fit replacement for specified Toyota, Lexus and Scion models, engineered to restore smooth wheel rotation and reliable ABS sensor performance.

This pair of front hub-bearing assemblies replaces worn or noisy units on compatible vehicles, returning factory-like fit and function without the premium dealer price. Each hub is precision forged from high-hardness carbon steel, finished with protective coating and seals to resist moisture and contamination. The assemblies are designed to match OEM dimensions and mounting points so they install with standard tooling and maintain correct wheel alignment and braking performance.

Which vehicles will this KNOLET hub assembly fit?

The 513257 hub is made to fit a range of Toyota, Lexus and Scion models across several production years. Confirm fit by selecting your vehicle year, make and model or by checking the vehicle fitment list to ensure compatibility before ordering.

• Toyota RAV4: 2006–2012
• Toyota Prius V: 2012–2017
• Toyota Corolla iM: 2017–2018
• Scion tC & xB: 2008–2015 (tC 2011–2016 referenced)
• Lexus HS250h: 2010–2012

How does this hub assembly improve ride quality and braking?

Replacing a worn hub stops common symptoms like rattling, steering vibration and grease leakage that undermine handling and braking response. The sealed bearing and balanced hub flange reduce noise and rotational drag, helping brakes and steering feel consistent under normal driving conditions.

• Anti-shock design reduces vibration transfer into the steering wheel
• Low-friction bearing surfaces support smoother wheel spin
• Durable seals keep grease in and road contaminants out
• Protective coating reduces corrosion in wet climates

What are the key specifications and installation details?

The KNOLET 513257 matches OEM-style dimensions so it mounts using factory bolt patterns and wheel studs. It’s intended for front left and right axles and includes a precision hub flange with five wheel studs and an encoder-compatible design for ABS systems.

• Position: Front, left and right axle compatible
• Flange diameter: 5.47"; bolt circle: 4.5"; hub pilot: 3.75"
• Wheel studs: 5; flange bolt holes: 4; brake pilot: 2.44"
• Reference numbers: 435500R010, 4355042010, 19340142

Can I install these hubs myself and what should I expect?

Technically-inclined DIYers with proper tools can replace front hubs, but some steps require torque specs, press or hammering, and ABS encoder attention. Many customers prefer a professional installation to ensure correct torque, wheel alignment and ABS sensor calibration.

• Designed for straightforward bolt-on replacement to OEM mounting points
• Expect to use a torque wrench and possibly a press or puller tool
• Check ABS sensor functionality and wheel torque after installation
• Replacing in pairs (both front hubs) is recommended for consistent performance

Who is this for? If your compatible Toyota, Lexus or Scion shows wheel noise, vibration, ABS fault codes, or visible hub corrosion and grease leakage, the KNOLET 513257 pair is a cost-effective, OEM-dimension replacement. It’s well suited for owners restoring safe steering and braking dynamics, independent mechanics seeking reliable aftermarket parts, and fleet operators needing durable, easy-to-install hub assemblies that reduce downtime.
