ECCPP Front Wheel Hub and Bearing Assembly 513121 — 5-Lug, ABS-Ready, Preinstalled Seal

ECCPP 513121 is a front wheel hub and bearing assembly engineered to replace the OE hub on compatible Buick, Cadillac, Chevrolet, Oldsmobile, Pontiac and Saturn models while restoring smooth, quiet wheel rotation and ABS sensor compatibility.

This complete hub-and-bearing unit comes preassembled and ready to bolt onto the front axle, matching the OE 513121 specification and designed for vehicles with a five-lug pattern and ABS. Built from corrosion-resistant materials with a high-quality seal and coated wheel bolts, the ECCPP assembly simplifies installation and reduces the need for press-fit bearing tools, making it a common aftermarket replacement for many late-1990s through 2011 GM front-wheel-drive and select AWD models.

Which vehicles will this ECCPP 513121 hub fit?

The hub is specified for numerous GM models. It fits many Buick front-wheel-drive sedans and crossovers from the late 1990s through 2011, plus select Cadillac, Chevrolet, Oldsmobile, Pontiac and Saturn AWD rear applications listed by year.

How does the ECCPP assembly improve installation and longevity?

This unit ships preassembled so you replace the entire hub-bearing package instead of pressing out and reusing inner bearings. The integrated seal and protective coatings help resist contamination and corrosion, which extends service life and helps maintain quieter operation under load.

• Preassembled hub and bearing saves time and avoids special press tools.
• High-quality sealing reduces dirt and moisture intrusion for longer life.
• Coated wheel bolts guard against rust and ease future removal.

What should I check before ordering and installing this hub?

Confirm the interchange number, wheel bolt pattern and whether your vehicle is front-wheel drive or AWD for rear hub applications. Inspect axle knuckle condition and replace any damaged fasteners; follow torque specs during installation to ensure safe operation.
