Notes:
Eaton differentials require special bearings. For axles with the small bearing race O.D. of 2.890 in., use bearing number TMK-LM102949 and race number TMK-LM102911. For axles with the larger bearing race O.D. of 3.060 in., use bearing number TMK-LM603049 and race number TMK-LM603012. Most 1999 and newer axles will use the larger bearing and race.
Special Attention:
Eaton recommends a petroleum/mineral based GL-5 80W90 gear oil for all Truetrac differentials. Do not use synthetic gear oil or friction modifiers.
Eaton Detroit Truetrac Differentials
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.
