  Q: How to Remove and Replace the Drive Shaft on Lincoln Town Car?

  A:

  The first step to remove and replace a driveshaft consists of placing the vehicle in neutral gear on a hoist. Color index the points where the driveshaft centering socket meets the rear axle pinion flange as well as the driveshaft joins the transmission extension housing. You should apply threadlock and sealer to the original bolts if new driveshaft flange bolts are not available. After removing the four bolts securing the rear axle pinion flange replace them with proper torque at 112 Nm (83 lb-ft). You must use the suitable tool to remove the driveshaft centering socket yoke from the rear axle pinion flange through its designated area because striking the shaft components is hazardous. To align the index marks the driveshaft and transmission extension housing possess, drop the rear end of the driveshaft beneath the rear axle housing before tugging it toward the rear so the slip yoke no longer enters the transmission extension housing. This operation necessitates the use of an extension housing plug to minimize fluid leakage. The centering socket yoke of the driveshaft requires a seat position that is directly aligned with the flange before evenly tightening bolts across the pattern. New bolts represent the ideal choice for this installation but using sealer on original bolts will also work if no new ones exist. Before continuing check for damage on the extension housing seal and perform replacement when needed while lubricating the slip-yoke spline with grease before trying to align the factory-set yellow paint marks between the driveshaft tube and rear axle pinion flange. Before reinstallation perform checks for external elements and component damage which requires fixing or replacing for a proper mating alignment.

  Q: How to Service and Repair the Drive Shaft on Lincoln Town Car?

  A:

  The repair and servicing procedure of drive/propeller shafts begins with properly raising the vehicle while applying a suitable form of support. The first index marks go on the driveshaft through paint spots placed on the rear axle companion flange and the slip yoke that touch the transmission output shaft center point. Start by removing the bolts which secure the driveshaft to the rear axle companion flange and then lower the driveshaft to slide it backward from the transmission output shaft while also plugging the extension housing to avoid fluid leakage. Check the extension housing seal for breaks before setup then exchange it for a new one if required. The slip-yoke spline requires installation of Premium Long-Life Grease XG-1-C or -K or an equivalent product based on Ford specification ESA-M1C75-B. Drive the shaft insertion by positioning the transmission output shaft index marks with the driveshaft slip yoke and the companion flange index marks with the driveshaft centering socket yoke. The installation should use new driveshafts by matching the yellow paint marks between the tube's back end and the companion flange of the rear axle. Finish the installation by executing the backward procedure.
