1. Mark shaft for assembly reference.
2. Support shaft in a horizontal line with a suitable vice.
3. On models with external snap rings, remove snap rings, Fig. 4 . If ring does not snap out of groove, relieve pressure on ring by tapping lightly on bearing cap.
4. On all models, place joint in tool No. J 9522-3 or equivalent with lower yoke ear supported by 1 1/8 inch socket, Fig. 5 , then press out cap. If cap is not completely removed, insert spacer tool No. J 9522-5 or equivalent and continue to press, Fig. 6 . If using a vice in place of special tool, use 1 1/8 inch socket to receive one cap and 5/8 inch socket to push opposite cap.
5. Rotate joint in tool or vice and press opposite cap out, then remove cross from yoke.
6. Inspect and clean retaining ring grooves.
7. Check cap bores for burrs and imperfections.
1. Use finger to coat needle bearings with thin layer of grease. Do not fill cups completely or use excessive amounts. Over lubrication may damage seals.
2. Put one bearing cap part way into one side of yoke, then insert cross into cap, Fig. 7 .
3. Press cross and cap into yoke until cap is flush with yoke ear.
4. Press opposite cap into yoke, ensuring trunnion alignment, Fig. 8 .
5. Continue to press cap into yoke ear while working cross to ensure free, unbinding movement until retainer groove clears inside of yoke. If binding occurs, stop pressing and check for misaligned bearings.
6. Snap retainers into place, Fig. 9 . Yoke can be sprung slightly with firm hammer blow if retainer is difficult to seat, Fig. 10 .
|Before disassembling any universal joint, examine the assembly carefully|
and note the position of the grease fitting (if used). Also, be sure to mark the yokes in relation to the propeller shaft for assembly reference. Failure to observe these precautions may produce rough vehicle operation resulting in rapid wear and parts failure, as well as placing an unbalanced load on transmission, engine and rear axle.
When universal joints are disassembled for lubrication or inspection, and
the old parts are to be reinstalled, special care must be exercised to avoid damage to universal joint spider or cross and bearing cups.
