17. Install new boot bands on the boots, then bend both

sets of locking tabs.

1 8. Lightly tap on the doubled-over portions to reduce

their height.

NOTE: Install the outboard joint in the knuckle

before installing the driveshaft into the differential

or intermediate shaft. Loosely install the spindle

nut this time.
19. Install the new set rings in the driveshaft groove

and intermediate shaft groove.

20. Apply a light film of grease around the set ring groove

on the inboard joint, then install a new set ring and

center it on the joint. The grease will keep the set

ring centered, making the installation of the joint

easier.

21. Install the inboard end of the driveshaft into dif-

ferential or intermediate shaft.

CAUTION:

• Always use a new set ring whenever the drive-

shaft is being installed.

• Make sure the left driveshaft locks in the differ-

ential side gear groove, and the inboard joint

subaxle bottoms in the differential.

• Insert the right driveshaft inboard joint subaxle

into the intermediate shaft until the intermedi-

ate shaft set ring locks in the groove in the right

driveshaft.

Apply light film of

grease before installing.
