Installation & Maintenance Notes

• Fluid Service (Critical): Always fill the transfer case with the manufacturer-recommended high-performance gear oil (such as DiaQueen LSD Gear Oil) prior to operation. Operating with low or improper fluid is the leading cause of internal bearing failure in Evo 10 transfer cases.

• Seal Refresh: While the T-case is removed, we highly recommend replacing the main input shaft seal and output axle seals to prevent future leakage.

• Professional Installation: Due to the complexity of the S-AWC system, installation should be performed by a professional technician familiar with AWD drivetrain removal. Ensure the driveshaft is properly indexed during re-installation to prevent vibrations.

• Pre-Install Inspection: Before final torque-down, check your vehicle’s front CV axle splines for excessive wear or rust to ensure a smooth, slop-free connection to the new transfer case.
