  Q: How to Safely Remove and Replace the Drive Shaft on Ford Crown Victoria?

  A:

  The process starts by depowering the fire suppression system for safety reasons during driveshaft service. Index the rear axle pinion flange together with the driveshaft centering socket yoke and transmission extension housing and driveshaft tube when the vehicle sits at neutral position on the hoist. New driveshaft flange bolts must be unavailable considering you can coat the original bolts with threadlock and sealer before removing them along with the four bolts that require tightening up to 112 Nm (83 lb-ft). A suitable tool enables disconnecting the driveshaft centering socket yoke from the rear axle pinion flange without using hammers. Pull the driveshaft backward until the slip yoke passes by the transmission extension housing to prevent fluid leakage by plugging the extension housing. The yoke should set properly against the flange base which can be achieved through consistent bolt tightening following a cross-pattern method to protect both components. Use long-life grease to lubricate the slip-yoke spline. Driveshaft vibration after installation requires alignment of the factory-applied yellow paint marks positioned on the driveshaft tube with the pinion flange marks on the rear axle. Measurement of mating surfaces should identify damaged or foreign material which needs proper replacement or repair to achieve a tight fit. Follow all safety procedures after powering up the fire suppression system when installing the unit. The installation process should be done backward from removal steps.

  Q: How to Service and Repair the Drive Shaft on Ford Crown Victoria?

  A:

  Start drive/propeller shaft repair and servicing by lifting and supporting the vehicle. Put a paint mark between the driveshaft centering socket yoke and the pinion flange for indexing the driveshaft. First remove all bolts from the pinion flange integrating the driveshaft to the driveshaft before lowering and sliding backward the driveshaft along the transmission output shaft while marking its slip-yoke to the transmission output shaft with paint. Secure the extension housing through plugging to stop fluid drain. A necessary inspection must be performed on the extension housing seal prior to installation to determine if replacement is needed. Use Premium Long-Life Grease XG-1-C or -K matching Ford specification ESA-M1C75-B or an equivalent product to lubricate the slip-yoke spline before installing the driveshaft while ensuring the alignment of the transmission output shaft index with the driveshaft slip-yoke and the pinion flange with the driveshaft centering socket yoke. Install new driveshafts by positioning their factory-applied yellow paint marks on the back of the tube with the corresponding marks on the pinion flange. Using the reverse order of removal complete the installation process.
