  Q: How to service the RH differential seals on Mercury Mariner?

  A: Begin service of RH differential seals when the vehicle sits in NEUTRAL and rests on a hoist with ignition set to OFF. Begin with removing retainers along with the LH splash shield then proceed to drain transmission fluid by removing the drain plug. Next, remove the RH halfshaft. The Slide Hammer and RH Halfshaft Fluid Seal Remover can efficiently extract the RH differential seal which needs to be discarded. Use the Output Shaft Oil Seal (4X2) Installer to put in the new RH differential seal before you return the RH halfshaft into position. Reinstall the drain plug after cleaning its threads with a small amount of thread sealant and torquing it to 40 Nm (30 lb-ft). Use clean transmission fluid to accomplish filling the opening at the transaxle side until the fluid level meets the fill plug hole base but thoroughly clean the fill plug space afterward installation. Transmission fluid for the transaxle should be examined and added through the check and fill plug located on its left side near the front of the unit. The procedure requires removal of the fill plug followed by fluid addition until mark indicates the bottom of the fill plug hole. The procedure ends with engine start-up followed by check of proper forward and reverse functionalities.
