Detailed Description

Timken 25877A is a manual transmission output shaft bearing designed around Timken’s tapered roller bearing technology. The bearing’s 1.375-inch inside diameter and 0.969-inch cone width provide the dimensional fit needed for rear output shaft service in Ford Mustang Warner T5 and T5 World Class transmissions. In this application, the bearing supports the output shaft where load control and rotational stability matter for consistent drivetrain performance.

Timken recommends replacing the inner cone and outer cup together to help maximize reliability and service life. For Ford Mustang owners servicing a rear manual transmission bearing, Timken 25877A offers a precise replacement option backed by Timken’s bearing engineering heritage.

What It Helps Solve

• Rear output shaft bearing noise in a manual transmission
• Excess shaft play or looseness in Warner T5 and T5 World Class units
• Rough rotation caused by worn tapered roller surfaces
• Load-related wear at the transmission output shaft
• Drivetrain vibration traced to bearing deterioration

Installation Notes and Tips

Confirm transmission type before ordering. This bearing is listed for rear-position use in 1985-2003 Ford Mustang applications with Warner T5 and T5 World Class transmissions. Inspect the matching cup/race during service and replace both bearing components together when wear is present. Verify shaft dimensions and bearing seating surfaces before assembly to ensure proper fit.

Quality Assurance

Timken is recognized globally for tapered roller bearing engineering and technical support. Part number 25877A is built to Timken’s dimensional and load-handling standards for manual transmission service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
