How to service and repair the driveshaft universal joint on Mercury Grand Marquis?

The next step before servicing the driveshaft universal joint starts with driveshaft removal without vise-clamping while setting it on a suitable workbench. Draw marks indicating how the driveshaft components should be placed in relation to the driveshaft tube for future balanced reinstallation. A C-Frame and Screw Installer/Remover tool removes snap rings before allowing bearing cups to be pressed out from the driveshaft through its necessary rotations. The use of vise grips is necessary to remove bearing cups when they resist complete press-out. Clean the yoke surfaces before proceeding to inspect all components for wear and damage when removing the driveshaft slip yoke along with centering socket yoke. Execute U-joint assembly by installing new bearing cups and spiders as complete assemblies which should be obtained from the U-joint service kits while pressing the bearing cups beneath the yoke surface. When the yellow snap rings fail to provide sufficient installation ease you can substitute them with black snap rings. Check the U-joint movement by hitting each yoke with a brass or plastic hammer during the inspection of both driveshaft sides. The bearing cups need to be placed 6.3 millimeters (0.25 inches) underneath the yoke surface when performing installations.

The Universal Joint in Mercury Grand Marquis is used to link the driveshaft to the axle assembly thus requiring independent joint movement whenever the car's suspension cavorts to conditions on the road. This joint consists of a cross with needle bearings located in hardened steel cups; it enables the power to be transmitted while at the same time angling up and down in response to the movement in suspension. Generally, Universal Joints arrive at the purchaser pre-lubricated and U Joints contain grease zerks for relubrication. In the past decades the Grand Marquis has incorporated several types of U Joint designs mainly with reference to their strength and serviceability for ease of overhaul. Worn 'U' Joints are clearly for example described as making gear shift noise and vibration at speed, which suggest that it has to be inspected and possibly replaced. Due to the subject's exposure to wear through the use it receives periodically, the condition of grease seals and clips should not be overlooked as this determines the efficient running of the U Joint.
