Universal Joints

Repair or service the universal joint containing a nylon ring by using tool set J 9522-3 and J 9522-5. Two necessary tools include U Joint Bearing Separator (J 9522-3) and U Joint Bearing Spacer Remover (J 9522-5). The first step should include supporting the propeller shaft horizontally on a press but avoid clamping the tubing in a vise because this could cause damage. Record clear markings at both ends of the propeller shaft to maintain the correct orientation. Set the universal joint within the lower yoke ear on a 30 mm (1 1/8 inch) socket. Proceed by using the U Joint Bearing Separator (J 9522-3) to divide the plastic retaining ring on the bearing cup before pressing the lower bearing cup out of the yoke ear. The U Joint Bearing Spacer Remover (J 9522-5) allows users to press out remaining bearing cups by placing it between the seal and the cup. The propeller shaft rotation will force the opposite bearing cup to exit before removing the cross piece as well as any leftover universal joint elements. Check the retaining ring grooves together with bearing cup bores for any signs of damage before cleaning them both. To assemble the yoke you must first drive a bearing cup into one yoke side while you position the cross to accept the trunnion without restriction. Pressibrate the bearing cup until it fully masters the yoke ear then perform these steps for the other side making sure trunnions maintain correct alignment. Check the needle bearings for misalignment in case binding takes place. Use the press tool to drive the bearing retainer groove out of the yoke before installing the retainer snap ring. A dead blow hammer can help you set the retainer correctly if required. Application of chassis grease to the snap ring may help its correct positioning within the bearing cup groove.

The J 9522-3 Universal Joint Bearing Separator and J 9522-5 Universal Joint Bearing Spacer Remover help replace the universal joint's external snap ring. First mark down the propeller shaft orientation for assembly reference then position it horizontally while being supported. First use pliers to pinch each snap ring end before possible cup end tapping for pressure release. The J 9522-3 works with either a 30 mm (1-1/8 inch) hex socket or a 27 mm (1-1/16 inch) socket to push out the lower bearing cup from the yoke ear while the lower yoke ear rests on this tool. Use the J 9522-5 between the seal and bearing cup so you can continue pressing out the cup when it does not fully detach. Use the propeller shaft rotation to push the bearing cup from the other side and then eliminate the crosspiece along with any left-over universal joint components. Check the clean status of bearing cup bores and retaining ring grooves prior to performing complete cleaning operations. Begin assembly by inserting a bearing cup into one side of the yoke then positioning the cross to allow easy trunnion seating before pressing the bearing cup to flush with the yoke ear. Position the second bearing cup while verifying trunnion alignment before sealing it inside the yoke. Push gently until you see the retainer groove then add the bearing retainer before continuing gentle pressure until both retainers snap securely. When retainer seating becomes difficult try using a dead blow hammer to gently open the yoke along with grease application on the snap ring to improve seating process.

You need the u joint bearing separator (J 9522-3) and u joint bearing spacer remover (J 9522-5) tools to swap the Universal Joint with a nylon injected ring. Place the propeller shaft on a level pressing surface and keep the tubing away from clamps to safeguard from harm. Locate marks on the propeller shaft to establish its transmission and rear axle ends. Fasten the lower ear of the yoke onto a 1 1/8 inch (30mm) socket. Press the u joint bearing separator (J 9522-3) to cut the plastic retainer on the bearing cup before pressing the lower bearing cup out of the yoke ear. After reaching the necessary depth with the full tool, you must take out the cross and fit the u joint bearing spacer remover between the seal and the bearing cup. Then continue pushing the tool. Use the rotating propeller shaft to drive the opposite bearing cup out of the Slip Yoke. Take note of its position to replicate installation during reassembly. Thoroughly examine the grooves of retaining rings and bores of bearing cups after removing cross and leftover Universal Joint parts. Rub off sheared plastic items from the grooves before seating new bearing cups into position. Place a single bearing cup into one side of the yoke and bend the ear downwards. Attach the cross easily as the trunnion fits into its center. Insert each yoke bearing cup until it rests flat against the surface while making sure trunnions fit precisely in place. Continue pressing until the bearing retainer groove becomes free of the yoke and check if the needle bearings need attention. Put together the bearing retainer and push until each retainer snaps into position. Use a dead blow hammer to settle the retainer if necessary and coat the snap ring with chassis grease as needed during installation.

Use the J 9522-3 Universal Joint Bearing Separator and J 9522-5 Universal Joint Bearing Spacer Remover to change the universal joint with an external snap ring. Set the propeller shaft gently on a press surface using markings that show where the parts need to go during reassembly. Use pliers to pinch and loosen snap rings before tapping the end of the lying mechanism gently when needed. Set the J 9522-3 tool on top of the horizontal bearing cups in the yoke ear and press the tool over the lower socket head (30mm hex). Push the J 9522-5 tool between seal and bearing cup when the full release does not happen. Press out the bearing cup while supporting the lowered cross above it. Turn the propeller shaft to push out the bearing cups with their opposite orientation for future reassembly. Examine both horizontal bearing cup bores for signs of defects after removing the cross and universal joint parts. Check the bearing cup and retaining ring grooves for any dirt or damage. Load a bearing cup into one yoke bore so the trunnion fits easily and push it to the yoke edge. Press the opposite bearing cup into the yoke while checking both trunnions run 100 percent smooth. Check if the needle bearings show misalignment when installation causes resistance. You should press down the tool once you see the bearing cup retainer groove and finish by snapping both holders into position. Using a dead blow hammer to hit firmly will help position the retainer if it is hard to put into place. Chassis grease on the snap ring will make it easier to set the retainer in place.

The replacement of a universal joint with a nylon injected ring requires the use of tools J 9522-3 Universal Joint Bearing Separator and J 9522-5 Universal Joint Bearing Spacer Remover. Set the propeller shaft horizontally on a press table while maintaining it away from vise clamps to prevent damage to the tubing. Put marks on the propeller shaft ends to maintain their correct positions. Set the universal joint into a 30 mm (1 1/8 inch) socket with its lower yoke ear facing up. Apply pressure from the J 9522-3 to shear the plastic ring of the bearing cup before removing the lower cup from the yoke ear. Use the J 9522-5 between the seal and bearing cup to drive out any remaining portions of the bearing cup which won't come out properly. After pressing the bearing cup from the opposite side rotate the propeller shaft to push it out. Proceed by removing the cross section and all remaining universal joint hardware. Check both the retaining ring grooves and bearing cup bores for damage before cleaning out any plastic shearing that would prevent new parts from seating correctly. To assemble the yoke start by inserting a bearing cup on one side followed by cross placement into the yoke while verifying trunnion freedom of movement. Press each bearing cup against the yoke ear so it becomes flush while maintaining the correct trunnion alignment for both sides. Verify proper connection before checking if needle bearings are lined up properly. Seating the bearing retainer requires additional force until the retainer groove releases from the yoke before applying the retainers for both sides using either hand pressure or a dead blow hammer to secure installation. You should apply chassis grease to the snap ring when putting it into the bearing cup groove to ensure proper placement.

To install the new universal joints, set the propeller shaft on a press table, make marks for connecting to the transmission and rear axle and then remove the shaft to measure the distance between the joints. Rest the lower ear of the Universal Joint in a (30 mm) 1 1/8 inch socket. Shear the plastic retaining ring on the bearing cup using the j9522-3 and push the lower bearing cup out of the yoke ear. Should the bearing cup remain attached, remove the cross and put j9522-5 between the seal and the bearing cup. Twist the propeller shaft counterclockwise to eject the bearing cup on the other side and disassemble the cross from the yoke; throw out all the Universal Joint parts since they cannot be put back together. Get rid of all the loose parts from the yoke and if getting a new front Universal Joint, eliminate the bearing cups from the Slip Yoke in the same manner. Make sure the grooves and bores of the retaining rings and bearings are free of anything that could hinder new bearing placement, then clear out the bearing cup grooves of sheared plastic. Before installation, unclip the bearing cups from the universal joints, grease the needle bearings and put one bearing cup halfway into the yoke's side. Align the yoke ear at a downward angle, place the cross to lower its trunnion into the bearing cup and press the bearing cup against the yoke ear. Put on the top bearing cup about halfway and make sure the trunnions are aligned, then press the cup into the yoke and check if the trunnions still move smoothly. Press the bearing until it is completely inside the yoke and stop if there is any tightening, since this could mean the parts are not perfectly aligned. After that, insert the bearing retainer into the groove and keep pressing until both retainers click into their places with some help from the chassis grease.

You need U-Joint Bearing Separator J. 9522-3 and U-Joint Bearing Spacer Remover J 9522-5 to work with external snap ring universal joints. Set the propeller shaft on a press table horizontally before starting any work to shield its tubing from harm. Use a marker to show where the transmission and rear axle connect to the propeller shaft. Using pliers squeeze the snap ring ends to open it then tap gently on the cup end if needed to reduce internal stress. Put the lower yoke ear on a 30mm hex head socket or 27mm socket and place U-joint Separator J 9522-3 on open horizontal bearing cups to extract the lower bearing cup from the yoke ear. Insert the U-Joint Bearing Spacer Remover (J 9522-5) between the seal and the bearing cup after lifting the cross to remove the spacer. Continue to push while passing the bearing cup. Use the propeller shaft rotation to remove the second bearing cup while marking the slip yoke setup position. Examine all grooves and bores in the bearing cups and retaining rings to check for cleanliness and damage near the parts' removal. Place half a bearing cup in one yoke ear first and join the trunnion smoothly into the assembled cross section. Use consistent force to press the bearing cups into their matching yoke ears and check for correct trunnion matching. Push downward until the bearing retainer grooves show and add the retainer parts before completing the press action when both parts click into position. A light strike from the dead blow hammer and chassis grease added to the snap ring make it easier to install the retainer properly.

Bring the tools required for this task: Universal Joint Bearing Separator (J 9522-3) and Universal Joint Bearing Spacer Remover (J 9522-5). Adjust the propeller shaft in a balanced position first while preventing any tool damage to the tubing. Mark the propeller shaft ends to orient the replacement parts correctly. Install the universal joint through the lower yoke ear onto the 30 mm (1 1/8 inch) socket. A Universal Joint Bearing Separator (J 9522-3) tool cuts through the plastic bearing cup ring before pushing out the lower bearing cup from the yoke ear. Use the Universal Joint Bearing Spacer Remover (J 9522-5) between the seal and the bearing cup to push it out when the cup does not come off completely. Turn the shaft to push out the other bearing cup while noting how the yoke faces the tube. Carefully measure the cross and leftover universal parts before examining the bearing cup slots and sealing bores for foreign objects or blemishes. Wipe out all sheared plastic material from the grooves before installing new bearing cups. After installing one bearing cup into the yoke you need to turn down its ear to put on the cross component and check trunnion free movement. Press the bearing cup into each yoke ear until it reaches flush with the surface and ensure trunnion alignment. You need to check the needle bearings for alignment if assembly is successful. Position the bearing retainer until it passes through the yoke and press it in place using a dead blow hammer if needed. Add chassis grease to the snap ring as needed before inserting it properly into the bearing cup opening.

Inspect the retaining ring grooves for dirt, corrosion, or old ring pieces, and clean them.

Repeat for the opposite bearing, ensuring the universal joint moves freely, tapping lightly if necessary.

Rotate the propeller shaft to press the opposite bearing cup out.

Support the propeller shaft horizontally, avoiding clamping on the tubing to prevent damage.

A dead blow hammer to slightly spring the yoke.

Insert the U Joint Bearing Spacer Remover (J 9522-5) between the seal and the bearing cup to continue pressing it out.

Position the universal spider in the slip yoke, install the universal bearings, and fully seat one spider.

Mark the ends of the propeller shaft for reassembly.

Mark the propeller shaft to indicate the transmission and rear axle connections.

Insert a bearing cup partway into one side of the yoke, position the yoke ear downward, and assemble the cross so the trunnion seats freely.

Lift the cross and insert the U-Joint Bearing Spacer Remover (J 9522-5) between the seal and the bearing cup, continuing to press it out.
