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

In order to service the driveshaft universal joint, unscrew the driveshaft; mark the position of components to be joined again. Removal of snap rings and bearing cups Use C-Frame. Wipe and clean yokes and replace new bearing cups and spiders. Installation depth and U-joint motion should be checked with the help of a hammer, when necessary.

Are the staked driveshaft universal joints serviced separately within the warranty period on Mercury Mountaineer?

Universal joints on staked driveshafts are not individually serviced during the warranty period. If they are worn or damaged, a new driveshaft must be installed. For high mileage repairs, universal joint service kits with instructions are available from a Ford authorized dealer.
