2003 Lincoln Town Car Differential Cover Parts Questions & Experts Answers

• Q: How to Service and Repair the Differential Cover on 2003 Lincoln Town Car?

  A: It is crucial to turn off the air suspension switch found on the left-hand side of the luggage compartment before maintenance of the differential housing cover because this action disables the electrical supply to the air suspension system thus preventing air spring inflation or deflation during service operations. Start by raising and supporting the vehicle before removing the differential housing cover through wrenching off bolts then draining its lubricant from inside. The installation process requires clean machined surfaces on both pieces with oil-free areas which need covering inside the rear axle to stop contamination during cleaning. Install the differential housing cover immediately after you place a continuous bead of clear silicone rubber on it since waiting longer than 15 minutes before installation requires fresh silicone sealant. Silicone sealant needs at least one hour of curing time before you can add lubricant into the axle. Fasten the differential housing cover while installing the bolts. Workers must first add 118 ml (4 oz) of friction modifier to the rear axle before filling it with 1.8 liters (3.75 pints) of the lubricants and finally installing the fill plug. Activate the air suspension before performing the vehicle lowering if the system exists on the vehicle.
