Product Overview
35-4406 Axle Differential Bearing and Seal Kit is a new independent aftermarket service kit for coordinated bearing and seal replacement on selected 140-series tandem axle differentials. A differential carrier depends on correctly matched bearing surfaces, stable preload, accurate alignment, and effective sealing to keep the ring-and-pinion assembly rotating smoothly. It brings the principal wear items into one service reference for rebuilds prompted by bearing distress, unstable preload, gear noise, or oil migration past aged seals.
This package groups related wear items for professional axle repair and driveline rebuilding. It does not change the axle ratio, carrier design, or installation procedure.

Service and Fitment Guidance
Confirm the tandem axle designation, carrier build, bearing identification, seal dimensions, and physical component profile against the removed assembly. Part-number matching alone is not enough because axle revisions, carrier positions, production changes, and previous repairs can affect the required components. Check the vehicle axle tag, service information, component markings, outside and inside diameters, widths, seal profiles, and the physical layout of the removed set.
- Inspect bearing journals, cups, bores, thrust surfaces, gears, fasteners, and lubricant before assembly.
- Use the axle maker’s current procedures for cleaning, preload, backlash, bearing adjustment, seal installation, torque values, and approved lubricant.
- Do not reuse damaged mating parts or mix unmatched bearing components. Installation should be completed by a qualified technician with appropriate measuring tools.
