Inspection
Thoroughly clean all parts in cleaning solvent, then dry with compressed air. Check parts for evidence of deformation and other damage.
DRIVE SHAFT
Replace drive shaft if it is twisted or cracked.
BOOT
Check boot for fatigue, cracks or wear. Replace with new boot and boot bands.
JOINT ASSEMBLY (TRANSAXLE SIDE) TS79C AND T86 TYPE
^ Check spider assembly for needle bearing and washer damage. Replace if necessary.
^ Check roller surfaces for scratches, wear and other damage. Replace if necessary.
^ Check serration for deformation. Replace if necessary.
^ Check slide joint housing for any damage. Replace if necessary.
^ When replacing only spider assembly, select a new spider assembly from among those listed in table below. Ensure that the number stamped on slide joint is the same as that stamped on new part.
Housing alone cannot be replaced. It must be replaced together with spider assembly.
D90+B TYPE
^ Replace any parts of double offset joint which show signs of scorching, rust, wear or excessive play.
^ Check serration for deformation. Replace if necessary.
^ Check slide joint housing for any damage. Replace if necessary.
JOINT ASSEMBLY (WHEEL SIDE)
Replace joint assembly if it is deformed or damaged.
SUPPORT BEARING
Make sure support bearing rolls freely and is free from noise, cracks, pitting and wear.
SUPPORT BEARING BRACKET
Check support bearing bracket for cracks with a magnetic exploration or dyeing test.
Assembly
^ After drive shaft has been assembled, ensure that it moves smoothly over its entire range without binding.
^ Use Genuine NISSAN grease or equivalent after every overhaul.
SUPPORT BEARING
