Detailed Product Overview

The FAG SR3570 is a shaft repair sleeve engineered to provide an additional sealing surface where the original shaft has been worn or damaged. Its 3.753-inch shaft diameter and 4.02-inch flange diameter support a precise fit, while the 0.688-inch shaft width and 1.8-inch installation depth help define the repair area. For Ford F-250, F-350, Bronco, E-Series vans, F-150, LTD, and related rear applications, this sleeve offers a practical way to address sealing wear without replacing the shaft assembly. This part cross-references Dorman HELP 99372 for the same application.

What It Helps Fix

• Grooved or worn shaft sealing surfaces
• Oil leakage caused by damaged seal contact areas
• Premature seal wear from shaft surface damage
• Costly shaft replacement when the base shaft is still serviceable
• Repair downtime tied to machining or full shaft removal
