Inner TRIPOT Joint And Seal: Assembly

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix and 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.
  1. Place the NEW small swage ring onto the small end of the joint seal. Slide the joint seal and the small swage ring onto the halfshaft bar. Position the small end of the joint seal into the joint seal groove on the halfshaft bar.
  2. Mount Swage Tool (J-41048) in a vise and proceed as follows:
    1. Position the inboard end of the halfshaft assembly in swage tool.
    2. Align the top of seal neck on the bottom die using the indicator.
    3. Place the top half of the swage tool on the lower half of the swage tool.
    4. Before proceeding, ensure there are no pinch points on the halfshaft inboard seal. This could cause damage to the halfshaft inboard seal.
    5. Insert the bolts. Tighten the bolts by hand until snug.
  3. Align the halfshaft inboard seal, the halfshaft bar and the swage ring. Tighten each bolt of swage tool 180 degrees at a time using a ratchet wrench. Alternate between each bolt until both sides are bottomed.
  4. Install the spacer ring into the groove of the halfshaft bar using Snap Ring Pliers (Parallel Jaw) (J-8059).
  5. Slide the tripot joint spider assembly toward the spacer ring as far as it will go on the halfshaft bar. Install the spacer ring into the groove of the halfshaft bar snap ring pliers (parallel jaw).
  6. Place approximately half of the grease from the service kit in the halfshaft inboard seal. Use the remainder of the grease to repack the housing.
    NOTE: Ensure the trilobal tripot bushing is flush with the face of the housing.
  7. Install the NEW trilobal tripot bushing to housing. Position the larger NEW seal retaining clamp on the halfshaft inboard seal. Slide the housing over the tripot joint spider assembly on the halfshaft bar.
  8. Slide the large diameter of the halfshaft inboard seal, with the larger clamp in place, over the outside of the trilobal tripot bushing and locate the lip of the seal in the groove.
    NOTE: The halfshaft inboard seal must not be dimpled, stretched out or out of shape in any way. If the halfshaft inboard seal is not shaped correctly, carefully insert a thin flat blunt tool, no sharp edges, between the large seal opening and the trilobal tripot bushing in order to equalize the pressure. Shape the halfshaft inboard seal properly by hand. Remove the tool.
  9. Position the joint assembly at the proper vehicle dimension. Dimension "A" is 5" (125.7 mm). See Fig 1 .
  10. Align the halfshaft inboard seal, the tripot housing and the large seal retaining clamp. Crimp the seal retaining clamp with Drive Axle Seal Clamp Pliers (J-35910) to specification. See TORQUE SPECIFICATIONS  . Add the breaker bar and the torque wrench to drive axle seal clamp pliers if necessary.
  11. Check the gap dimension "A" on the clamp ear. Tighten until gap dimension of 0.102" (2.60 mm) is reached. See Fig 2 .
