KNOLET Rear Wheel Hub Assembly Pair 512403 for Toyota Corolla/Matrix & Pontiac Vibe — 5-Lug Front with ABS, OEM Fit

This two-piece hub assembly kit includes both left and right front units (with integrated ABS tone rings) and is engineered to meet the dimensional and durability expectations of the original equipment. Built from high-hardness forged carbon steel with protective coatings and premium seals, these hubs are intended to replace worn or noisy wheel bearings and return reliable, low-drag operation to compatible vehicles.

Which vehicles will these KNOLET 512403 hub assemblies fit?

The KNOLET 512403 hubs are manufactured to match OEM fitment for specific Toyota and Pontiac models. Check year, make and model compatibility carefully before purchase to ensure correct fit; the assemblies are FWD front-axle units with 5 wheel studs and ABS sensor tone rings.

• Toyota Corolla 1.8L: 2009–2019
• Toyota Corolla 2.0L: 2019
• Toyota Corolla 2.4L: 2009–2010
• Toyota Matrix Base 1.8L: 2009–2013 (FWD only)
• Pontiac Vibe Base 1.8L: 2009–2010 (FWD only)

How do these assemblies improve driving feel or stop wheel noise?

Worn hubs and bearings commonly cause rattling, steering vibration, and grease leakage; replacing them with properly machined assemblies reduces friction and restores proper wheel alignment and rotation. KNOLET hubs use precision manufacturing and sealing to minimize play and contamination that lead to noise.

• Precision OEM-style dimensions to reduce radial/runout
• Premium seals to keep grease in and dirt out
• High-hardness forged carbon steel for impact resistance
• Anti-shock design and low friction for smoother rotation

What are the key specifications and included features?

This product is sold as a pair and includes the integrated ABS sensor ring. The listing includes reference part numbers for cross-checking and lists full flange and pilot measurements so installers can verify fit before purchase.

• Position: Front left and right axles (pair)
• Flange diameter: 5.31"; bolt circle diameter: 3.94"
• Hub pilot diameter: 2.91"; brake pilot diameter: 2.17"
• Wheel stud qty: 5; flange bolt holes: 4; ABS sensor included

How simple is installation and what should a DIYer expect?

Installation is typical for front hub replacement: remove the wheel, caliper, rotor and old hub, then install the new assembly and torque to manufacturer specs. KNOLET hubs are designed for a trouble-free swap, but correct tools and torque procedures are important for safety and longevity.

• Sold as a two-piece kit for both front sides, saving repeat orders
• OE-style fit minimizes additional machining or adapters
• Requires standard mechanic tools and correct torque values
• Inspect axle nut, bearings and seals during service for best results

Who is this for: The KNOLET 512403 wheel hub assembly pair is intended for owners and mechanics working on compatible Toyota Corolla, Matrix, and Pontiac Vibe models who need a reliable OE-dimension replacement with ABS compatibility. It's suitable for those replacing noisy, loose, or leaking wheel bearings and for routine front-end maintenance when original hubs show wear. Always confirm vehicle compatibility using the year/make/model selector or part reference numbers before purchase.
