Front Half Shaft, Inner Boot - Installation

INSTALLATION

Special Tools:











NOTE: The inner tripod joint sealing boots are made from two different types of material. High-temperature applications (close to exhaust system) use silicone rubber whereas standard temperature applications use Hytrel plastic. The silicone sealing boots are soft and pliable. The Hytrel sealing boots are stiff and rigid. The replacement sealing boot MUST BE the same type of material as the sealing boot that was removed.

1. Slide inner tripod joint seal boot retaining clamp onto interconnecting shaft (4)(Figure 1). Then slide the replacement inner tripod joint sealing boot (1) onto interconnecting shaft. Inner tripod joint seal boot MUST be positioned on interconnecting shaft, so the raised bead on the inside of the seal boot is in groove (3) on interconnecting shaft.






NOTE: The rollers can fall off, use caution when installing the tripod

2. Install spider assembly (1)(Figure 2) onto interconnecting shaft with chamfer (3) on spider assembly toward interconnecting shaft (2).





3. Spider assembly (2)(Figure 3) must be installed on interconnecting shaft (3) far enough to fully install spider retaining snap ring. If spider assembly will not fully install on interconnecting shaft by hand, it can be installed by tapping the spider body with a brass drift (4). Do not hit the outer tripod bearings in an attempt to install spider assembly on interconnecting shaft.





4. Install the spider assembly (2)(Figure 4) to interconnecting shaft retaining snap ring (3) into groove on end of interconnecting shaft. Be sure the snap ring is fully seated into groove on interconnecting shaft (1).





5. Distribute 1/2 the amount of grease provided in the seal boot service package (DO NOT USE ANY OTHER TYPE OF GREASE) into tripod housing. Put the remaining amount into the sealing boot (3)(Figure 5).
6. Align tripod housing (1) with spider assembly (2) and then slide tripod housing over spider assembly and interconnecting shaft.





7. Install inner tripod joint seal boot to interconnecting shaft clamp (3)(Figure 6) evenly on sealing boot (4).
8. Clamp sealing boot onto interconnecting shaft using Clamp and the following procedure. Place Clamp over bridge of clamp.





9. Tighten nut on Clamp (Figure 7) until jaws on tool are closed completely together (2), face to face.






CAUTION: Seal must not be dimpled, stretched, or out-of-shape in any way. If seal is NOT shaped correctly, equalize pressure in seal and shape it by hand.

10. Position sealing boot into the tripod (3)(Figure 8) retaining groove. Install seal boot retaining clamp (2) evenly on sealing boot (1).

CAUTION: The following positioning procedure determines the correct air pressure inside the inner tripod joint assembly prior to clamping the sealing boot to inner tripod joint housing. If this procedure is not done prior to clamping sealing boot to tripod joint housing, boot durability can be adversely affected.

CAUTION: When venting the inner tripod joint assembly, use care so inner tripod sealing boot does not get punctured or, in any other way, damaged. If sealing boot is punctured or damaged while being vented, the sealing boot can not be used.

11. Insert a trim stick (4) between the tripod (3) and the sealing boot (1) to vent inner tripod joint assembly. When inserting trim stick between tripod housing and sealing boot, ensure trim stick is held flat and firmly against the tripod housing. If this is not done, damage to the sealing boot can occur. If inner tripod joint has a Hytrel (hard plastic) sealing boot, be sure trim stick is inserted between soft rubber insert and tripod housing, and not the hard plastic sealing boot and soft rubber insert.





12. With trim stick inserted between sealing boot (2)(Figure 9) and tripod joint housing (4), position inner tripod joint on halfshaft until correct sealing boot edge to edge length (1) is obtained for type of sealing boot material being used. Then remove the trim stick.





13. With trim stick inserted between sealing boot (2)(Figure 10) and tripod housing (4), position inner tripod joint on halfshaft until correct sealing boot edge to edge length (1) is obtained for type of sealing boot material being used. Then remove the trim stick.





14. Clamp (1)(Figure 11) tripod joint sealing boot (4) to tripod joint (2) using required procedure for type of boot clamp application. If seal boot uses crimp type boot clamp, clamp sealing boot onto tripod housing using Clamp (3). Place Clamp over bridge of clamp (1).





15. Tighten nut on Clamp (3)(Figure 12) until jaws on tool (3) are closed completely together (4), face-to-face.





16. If seal boot (3)(Figure 13) uses low profile latching type boot clamp, clamp sealing boot onto tripod housing using Clamping Tool, Snap-On(R) YA3050 (2) (or an equivalent). Place prongs of Clamp Locking Tool in the holes of the clamp (1).





17. Squeeze tool together until top band of clamp is latched behind the two tabs (2)(Figure 14) on lower band of clamp.
18. Install the halfshaft requiring boot replacement back on the vehicle. Half Shaft - Installation
