Proper Drive Axle Lubricant Level:
• Regular inspection of the drive axle lube levels is an essential
maintenance procedure.
• The lubricant should be level with bottom of the hole.
• Important: The lube level close enough to the hole to be seen or
touched is not sufficient. The lube must be level with the hole.
• The differential is filled with API GL-5 or MT-1 type gear lubri-
cant, Pennzoil Gear Plus Super-EW 75w-90.
NOTE: When checking the lube level also check the hous-
ing breathers. Clean the breathers if dirty or replace them
if damaged.
Greasing the Driveline Universal Joint:
1. Check the driveline for looseness. If loose, service as necessary.
2. Apply the specified grease at the grease fitting on the universal
joint. Apply grease until the new grease purges from all the seals.
3. If the new grease does not purge at the seals loosen the bearing
cap bolts and regrease until all four caps purge. If the new
grease still does not purge replace the universal joint.
Greasing the Driveline Slip Yoke and Splines:
1. Check the driveline for looseness. If loose, service the driveline
as necessary.
2. Cover the air hole so that grease can flow easily to the seal.
Apply the specified grease at the grease fitting on the slip yoke.
Apply grease until new grease purges from the air hole in the
end of the slip yoke. Greasing Intervals-10,000 miles or annually.
