National 6712NA Wheel Seal - Front or Rear

National 6712NA Wheel Seal for Front Applications

National 6712NA is a front wheel seal built for driveline and axle sealing applications where the shaft and housing dimensions must match precisely. It uses a polyacrylate sealing material and a clockwise-spiral lip design to help maintain a consistent seal in service.

With Redicoat protection and National’s long history in sealing technology, this oil seal is a direct-fit option for a wide range of classic and late-model vehicles, including Chevrolet Tracker, GMC Jimmy, and Honda Passport applications.

Detailed Description

National 6712NA is engineered as a wheel seal for front axle and driveline sealing points that require a 1.875-inch shaft diameter and a 2.758-inch housing bore. The polyacrylate sealing material is selected for sealing performance in demanding automotive environments, while the spiral lip profile supports controlled sealing contact during rotation. This seal is part of National’s 6000 series and is identified as Type 75.

Use this seal when servicing front-end sealing on vehicles such as the 1994-2002 Honda Passport, 1996-1999 Acura SLX, and 1991-1998 Suzuki Sidekick, as well as many Chevrolet and GMC truck and SUV applications. National 6712NA also cross-references ATP CO-4 and Continental 49713 for the same application.

Common Problems This Seal Can Address

• Gear oil or lubricant leakage at the wheel seal area
• Contamination entering the hub or axle sealing surface
• Seal wear from age, heat, and rotation
• Noise or rough operation caused by compromised sealing surfaces
• Service issues on front axle or driveline sealing points

Installation Notes and Tips

Confirm shaft diameter, housing bore, width, and flange dimensions before installation. Inspect the sealing surface for grooves, scoring, or corrosion, and replace worn sleeves or damaged components as needed. Clean the bore thoroughly and install the seal squarely to avoid lip distortion. Verify the application by year, make, model, position, and transmission or axle notes where listed, especially on Chevrolet Tracker, GMC Tracker, and Jaguar applications with specific transmission references.

Quality Assurance

National has supplied sealing solutions for more than 75 years and continues to develop sealing components for modern and legacy vehicles. Part number 6712NA reflects that sealing-focused engineering approach for front wheel seal service across a broad range of applications.
