Detailed Description

SKF 15666 is a wheel seal for the rear inner position on the Ford Focus across the 2000-2008 model years. The seal uses a nitrile sealing surface and is dimensioned at 0.630 inches wide, 1.909 inches outside diameter, and 1.563 inches shaft diameter. Those measurements are important when matching the seal to the hub and shaft interface during axle and wheel-end service. SKF 15666 is a practical choice when replacing a worn seal on a Ford Focus rear inner wheel end, especially where lubricant retention and contamination control are critical.

SKF has a long history in seal engineering, including early integrated shaft seal development and continued refinement of sealing materials and bonding methods. This part reflects that focus on application-specific design and manufacturing consistency. This part cross-references Ford OE number 1M5Z1S175AC for the same application.

What It Helps Address

• Gear oil or grease leakage at the rear inner wheel end
• Contamination entering the sealed hub or axle area
• Noise or wear caused by a deteriorated wheel seal
• Seal replacement during Ford Focus rear axle or hub service
• Fitment-specific repair needs on 2000-2008 Ford Focus models

Installation Notes and Tips

Confirm the seal dimensions against the hub and shaft before installation. Inspect the sealing surface for scoring, corrosion, or wear, and clean the bore thoroughly so the new seal seats evenly. During service on a Ford Focus rear inner wheel seal, verify that the mating surfaces are smooth and that the seal is installed squarely to avoid premature leakage.

Quality Assurance

SKF manufactures seals to specific designs using premium materials and controlled production standards. The brand’s seal engineering background and long-term focus on keeping lubricants in and contaminants out support dependable service life in wheel-end applications.
