Standard
L: Refer to FAX-32, "Drive Shaft". Front Axle
CAUTION:
^ If the boot installation length is outside the standard, it may cause breakage in boot.
^ Be careful not to touch the inside of the boot with the tip of tool.

Inspection
INSPECTION AFTER REMOVAL
^ Move joint up/down, left/right, and in the axial directions.
^ Check for motion that is not smooth and for significant looseness. Check boot for cracks, damage, and leakage of grease.
^ Disassemble drive shaft and exchange malfunctioning part if there is a non-standard condition.
INSPECTION AFTER DISASSEMBLY
Shaft
Check shaft for runout, cracks, or other damage. Replace it if necessary.
Joint Sub-Assembly (Wheel Side)
Check the following items, replace the parts if necessary.
^ Joint sub-assembly for rough rotation and excessive axial looseness.
^ The inside of the joint sub-assembly for entry of foreign material.
^ Joint sub-assembly for compression scars, cracks, and fractures inside of joint sub-assembly. Replace joint sub-assembly if there are any non-standard conditions of components.
Housing and Spider assembly (Final Drive side)
Replace housing and spider assembly if there is scratching or wear of housing roller contact surface or spider roller contact surface.
