  Q: How to Properly Service a Universal Joint with an External Snap Ring on Chevrolet Colorado?

  A:

  Mount the propeller shaft on a press table to change the Universal Joint without the risk of harm. Set up the propeller shaft horizontally at the beginning. Indicate on the propeller shaft the positions where transmission and rear axle connections will be made. When the snap rings resist being removed use pliers, and then lightly hit the cup's end with a hammer to ease pressure. Press the lower bearing cup out of the yoke ear by placing j 9522-3 on the open horizontal bearing cups. Support this side of the yoke its 30 mm hex socket fixture or 27 mm socket. Use j 9522-5 between the seal and bearing cup to complete removal when the cup remains stuck. Turn the propeller shaft to push the opposite bearing cup toward the Slip Yoke while keeping note of its alignment with the tube for assembly. Take off the cross and all Universal Joint components from the yoke. Also remove bearing cups from the Slip Yoke if replacing its front Universal Joint unit. Check the sealing ring slots and bearing cup bores for residue and signs of damage then remove it through cleaning methods. Put one bearing cup into the yoke first by placing the yoke ear down and the cup into one side of the assembly. Set the cross into the yoke and push bearing cup down to rest on its associated trunnion space. Works the bearing cup half way into the yoke ear while aligning the trunnions to straight entrance for both bearing cups. Use the opposite bearing cup to test trunnion movement; check the needle bearings if trunnions become stuck when pushed. Push the bearing cup straight into position while watching until the bearing cup retainer notch becomes visible. Afterward, insert the bearing retainer into the groove and push until it clicks into place on both retainer sides. A stroke from a dead blow hammer followed by smeared grease on the snap ring can assist with retaining unit installation.

  Q: How to replace the universal joint with an external snap ring on Chevrolet Colorado?

  A:

  To fix the universal joint start by preparing these tools U-Joint Bearing Separator model J 9522-3 and U-Joint Bearing Spacer Remover tool J 9522-5. Keep the propeller shaft in a horizontal position while supporting it and never fit the tubing in a vise because it damages the shaft. Label the shaft ends before taking out the snap rings with pliers. Lightly tapping on the cup will help the ring exit when it does not come out freely. Set the lower yoke support onto either a 30 mm (1-1/8 in) hex socket head or a 27 mm (1-1/16 in) socket tool. Then use the U-Joint Bearing Separator (J 9522-3) device to push the lower bearing cup out from the horizontal opening. Install the U-Joint Bearing Spacer Remover tool (J 9522-5) when the standard process to remove the bearing cup does not work. Use the propeller shaft rotation to push out the other bearing cup and temporarily note its position for correct reassembly. Look through the bores of the bearing cups and retaining ring grooves for debris then assess each area for irregularities in the surface. Insert one bearing cup into the yoke side then fit the cross over it before pushing the cup until it meets the surface of the yoke. Apply the second bearing cup to its proper location and press it into position while making sure the trunnions line up. After seeing a clear slot in the retainer groove you must press both bearing retainers into place before using a dead blow hammer when needed to fully seat the retainers. The snap ring installation is smoother with a coating of chassis grease for the operation.
