Frequently Asked Questions
How do I verify Eaton 26664-00S is the correct service kit?
Match the original Eaton differential part number, axle family, spline count, internal design, and every supplied component before disassembly.
Can similar Eaton service parts be substituted?
No. Retainers, armatures, stators, clips, and internal hardware can differ by axle and differential revision even when they look alike.
Should the differential be inspected while it is apart?
Yes. A qualified technician should inspect bearings, races, gears, shafts, seals, wiring where applicable, backlash, preload, and contact pattern before reassembly.
Installation Instructions
Professional drivetrain installation is recommended. Confirm the axle and component identity before disassembly, inspect all reusable parts, follow current Eaton and vehicle service procedures, establish bearing preload and backlash, verify the gear contact pattern, use the specified lubricant, and test operation before returning the vehicle to service.
