stamped straps, loose bearing retainer or strap bolts,
loose companion flange bolts and nuts, loose or
missing spring tabs or spring tab bolts, damaged
tangs on end fittings, damaged or missing snap rings
and rotating bearing cups.
• If any of these situations are evident, replacement of
the component is necessary.
• Check all input a
Take hold of the end fitting with both hands.
Try to move it vertically and horizontally to feel
any looseness.
• There should be less than .006” movement in the
U-joint relative to the end yoke. If looseness in greater
than .006” the U-joint should be replaced.
• Check for the presence
of all grease zerks
fittings. Damaged zerks
should be replaced.
Loose zerks should
be tightened.

Lubrication Intervals
For (on-highway) applications, Spicer Life XL U-joints do not

• Meeting N.L.G.I.; EP., Grade 2 specifications
• Grease must have operating range of +325°F to -10°F
• Must be compatible with Lithium soap types
Mark Driveshaft (Phasing Marks)
• Mark all mating driveshaft components with a paint
marker to assure proper phasing during reassembly.
• Reassembly of a driveshaft that is out of phase can
cause vibration and failure to driveshaft components.
Grease Zerks

•
• Zerk should be lined up with outboard bearings
• Clean zerk nipples before greasing

Lubrication Procedure
1. Use a recommended lubricant to purge all 4 seals of
each U-joint.This flushes abrasive contaminates from
each bearing assembly and assures proper filling.
2. Ensure fresh grease is evident at all U-joint
bearing seals.
IMPORTANT
If any of the seals fail to purge, move the driveshaft from side to
side while applying grease gun pressure.
a. If all 4 bearing positions still will not purge,
releasing seal tension may be necessary.
b. Remove the bearing plate bolts and straps.
Do not reuse bolts or straps.
c. Once the bearing cups are free, allow the
driveshaft to rest on support strap.
d. Apply a c-clamp around the inboard bearings.
e. Apply grease gun pressure. Completely purge
both bearings.
