Detailed Description

Timken 225225 is a precision wheel seal designed for driveline and axle sealing applications where lubricant retention and contamination control are critical. The seal’s ribbed inner diameter helps it seat against minor spindle irregularities, while the contamination exclusion design helps reduce debris intrusion that can lead to leakage. Its vented design also supports lubricant circulation around the lip to help dissipate heat during operation. This part cross-references National 225225 for the same application.

Compatible With 2003-2009 Kia Sorento, rear; 2002-2005 Kia Sedona, rear inner; 1986-1987 Mazda B2000, front inner; 1987-1993 Mazda B2200, front inner; and 1987-1993 Mazda B2600, front inner. Timken 225225 is also used in additional rear inner and rear applications across the listed fitment range.

What It Helps Solve

• Wheel-end lubricant leakage at the hub or spindle
• Contamination entering the seal area from road debris
• Seal wear caused by heat build-up in the wheel-end assembly
• Poor sealing on spindles with minor surface imperfections
• Repeat seal failure after prior installation damage

Installation Notes and Tips

Inspect the spindle, housing bore, and sealing surface before installation. Clean away old grease, corrosion, and debris so the seal seats evenly. Verify the dimensions match the application before pressing the seal into place, and install carefully to avoid distorting the reinforced case.
