other deformity of universal joints will prevent
accurate mating with the crosses and bearings. This
will cause misalignment, which is accompanied by
vibration and excessive wear.
WARNINGS
To prevent personnel injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
To prevent serious injury or death, DO
NOT go under vehicle when the engine is
running. Rotating shafts can be dangerous.
You can snag clothes, skin, hair, hands, etc.
1. Using suitable lifting equipment, position driveline
assembly (1) on the vehicle and align match marks
on universal joints (2) with those on its mating
surfaces.
2. Apply Loctite 242 to the threads of capscrews (4)
and secure universal joints (2) to their mating
surfaces with capscrews (4). Tighten capscrews (4)
to a torque of 135 Nm (100 lbf ft).
3. Ensure the parking brake is applied and start the
engine. Remove wheel blocks from all road wheels.
DRIVELINE DIAGNOSIS CHART
CONDITION
Vibration or Noise
Excessive wear of
universal joints
SM 1577 12-98
REASON
Driveline bent or out of balance
Driveline loose at yoke/flange
Poor yoke/flange alignment
and/or run-out
Driveline imbalance
Driveline - Front Driveline
MAINTENANCE
Lubrication
Lubricate driveline with either a hand-operated or a
pressure grease gun. Refer to Section 300-0020,
LUBRICATION SYSTEM, for recommended lubricant
and service intervals.
Periodic Inspection
Use a small pry bar to check companion flange
yokes for looseness. If loose, drop one end of the
driveline and twist the yoke to check backlash
between splines and yokes. Replace any yoke that
does not fit snugly.
Using a small pry bar, check the universal joints for
play. If loose, replace the universal joints. Check
splines at slip joint and replace universal joints, if
excessively worn.
Note: In the event of a failed or worn bearing, a new
universal joint with a new set of bearings must be
installed.
SPECIAL TOOLS
There are no special tools required for procedures
outlined in this section. Refer to Section 300-0070,
SERVICE TOOLS, for part numbers of general service
tools required. These tools are available from your
dealer.
REMEDY
Clean driveline in a suitable solvent. Inspect for
contact with adjacent parts. If driveline is distorted or
sprung, replace. If driveline does not run smoothly,
and vibration is felt, remove driveline and dynamically
balance the assembly.
Check driveline mounting capscrews for tightness. If
loose, replace capscrews and torque tighten to the
proper specification.
Check yoke/flange for alignment, run-out and balance.
Repair or replace as required.
Check to see if balance weights are missing or if
driveline is distorted. If driveline is distorted, replace;
if weights are missing, check balance of driveline
dynamically and rebalance.
