Here is the procedure from the Chrysler Manual:
Disassembly
1) Straighten the tabs on the focer and remove the cover and gasket. Push the body back and remove the buttons, springs, ball and rollers and washers from both ends of the trunnion pin.
2) Remove the cover clamps and polished jute breather located between the shaft and the rear end of the cover. Save the breather.
3) Clean and examine the trunnion pin and raceways in the body for excessive wear. If wear is excessive, replace the body. If either part is to be replaced, use hydraulic press and Installing and Removing Jig C-3567 on all eight cylinder models, except those with 273 cubic inch engines. On models with 273 cubic inch and six-cylinder engines, use Jig C-3313.
Cleaning and Inspection.1) Clean all the parts in suitable solvent. If the trunnion pin, body or dust cover have not been removed, make sure that the body and cover are clean inside as well as outside.
Assembly.
1) When the trunnion pin and body have not been removed, a new dust cover can be installed, after coating all parts with Universal Joint Grease. Without using tools, stretch the cover over the pin and work it by hand through the body into position on the shaft.
2) If the trunnion pin is removed, install it or a new pin in the propeller shart, using a hydraulic press and the correct jig, as specified above. The pin is properly centered when the press ram contacts the spacer portion of the jig.
3) Pack the balls and rollers with Universal Joint Grease, NLGI Grade 2. Install a thrust washer, ball and rollers, button spring and centering button on the each end of the trunnion pin.
4) Position the dust cover and the jute breather on the propeller shaft with the jute breather parallel to the shaft and extending one=-half inch outside the small end of the cover. Install and tighten the small clamp. Position the dust cover on the body and install and tighten the large clamp.
5) Lubricate the joint with two ounces of Universal Joint Grease NLGI Grade 2, applying it evenly in both raceways, one-half back of the trunnion pin and one-half between the pin and cover.
NOTE: Two ounces of lubricant would be about 1/2 inch deep if placed on the grease cover. Do not use more than the specified amount and do not place lubricant in the dust cover.
6) Install a new gasket on the cover and position the cover and gasket on the body with the tabs in the grooves in the body. Bend the tabs to secure the cover to the body.
If you need Illustrations let me know so I can scan them for you. Good luck!
