How to Service and Repair the Drive Shaft on Mercury Grand Marquis?

Start driveshaft service procedures by preparing the vehicle for work through a neutral gear position on a hoist setup. Perform an index mark process for the rear axle pinion flange and driveshaft centering socket yoke and transmission extension housing and driveshaft tube. Install each of the four bolts tightly to 112 Nm (83 lb-ft) torque settings after attaching them. Take great care since the driveshaft centering socket yoke establishes a tight connection with the rear axle pinion flange pilot and you should not strike the driveshaft or its elements. A proper tool should only be used to pry away the yoke from the flange at its designated prying location. Lower the driveshaft's rear end until it passes through the back of the axle housing while using a transmission extension plug to stop fluid leak. The installation requires fresh bolts but you can use threadlock and sealer onto original bolts when new bolts are not available. The driveshaft centering socket yoke should be aligned perfectly onto the flange before applying a balanced cross-pattern bolt tightening sequence. The inspection of extension housing seal reveals damage which requires replacement while long-life grease should be applied to slip-yoke spline. Drivers must ensure the correct alignment of a new driveshaft by matching the factory yellow paint marks between the driveshaft tube and the pinion flange marks although these features may be hidden before continuing with driveshaft indexing. After inspecting the mating surfaces of the rear axle pinion flange together with the driveshaft centering socket yoke you should check for foreign matter and damage then replace damaged components to achieve a proper fit. The installation should follow the instructions for the removal process in reverse order.

How to Service and Repair the Rear Drive Shaft of a 4x2 on Mercury Mountaineer?

Begin servicing the 4x2 vehicle rear driveshaft by hoisting the vehicle with transmission in neutral mode. You should check that extension housing index marks sync with driveshaft index marks before making separation. After drive shaft removal apply an index on transmission output shaft which needs to match the mark on extension housing. The maintenance of drive system balance requires marking the driveshaft flange with the pinion flange. Obtain the four driveshaft flange bolts then replace them with new ones and tighten them to 112 Nm (83 ft. lbs.). When detaching the driveshaft flange yoke from the pinion flange pilot use a suitable tool instead of hammering to gently pry from the designated area. A proper installation of the driveshaft flange on the pinion flange requires adjustable bolt torque while using a star pattern sequencing method. Post-thread coating of original bolts with threadlock and sealer allows their reuse as long as the installation follows the reverse steps of removal.
