How to service the differential seals on the right-hand side of an All Wheel Drive (AWD) on Lincoln MKZ?

Service of right-hand AWD differential seals starts with removing the Power Transfer Unit (PTU). You can extract the differential fluid seals by using the Input Shaft Oil Seal Remover and Slide Hammer. Position the new inner differential fluid seal first before securing it with both the Differential Seal Installer and Handle. The installation of the new outer differential fluid seal requires the same procedures as the preceding operation. Reinstall the PTU. Engage engine idling at 680-780 rpm when vehicle rests on a flat surface together with the transaxle set to PARK and brake pedal maintained for gear lever selection from each position before final returning to PARK. Clean the transmission fluid level indicator cap and remove its indicator before wiping it with a clean cloth. Check the transmission fluid level accurately by maintaining the vehicle at level ground while allowing the engine to reach operating temperature between 60°C-70°C (140°F-158°F). The fill plug nearby the indicator permits fluid additions in 0.25L (1/2 pt) increments but drivers must avoid overfilling because it will damage the transaxle. Read the fluid level at normal temperature against the top part of the fluid indicator since this mark indicates the exact fluid amount needed. When the engine operates at the cold temperature range of 15°C-25°C (59°F-77°F) the fluid level needs to be positioned at the marker located at the bottom. You should top off the transmission with cold-fluid range when Transmission Fluid Temperature (TFT) is low before checking the level as the transaxle reaches its normal operating temperature. The process ends by reinstalling the transmission fluid fill plug and torquing it to 39 Nm (29 lb-ft).
