TROUBLE SHOOTING
NOTE: See appropriate table in TROUBLE SHOOTING article in GENERAL
INFORMATION.
REMOVAL & INSTALLATION
AXLE SHAFT & HUB BEARING
Removal
1) Raise and support vehicle. Remove wheel. Remove brake
caliper with hose attached, and secure aside. DO NOT allow brake
caliper to hang by brake hose. Remove brake rotor. Remove ABS wheel
speed sensor (if equipped). Remove grease cap from center of front
hub. Remove cotter pin from end of axle shaft. Remove axle nut and
washer.
2) Remove hub/bearing assembly-to-knuckle bolts. Remove
hub/bearing assembly from steering knuckle and axle shaft. Remove
brake dust shield. To remove right (passenger-side) axle shaft,
carefully pull axle shaft from axle housing.
NOTE: Left axle shaft will disengage from collar located on
intermediate axle shaft.
3) To remove left (driver's side) axle shaft, disconnect
electrical connector and vacuum hoses at vacuum shift motor. Remove
bolts, vacuum shift motor and gasket. Carefully pull axle shaft from
axle housing and collar on intermediate axle shaft.
Installation
1) Install NEW oil seal on axle shaft with seal lip facing
toward splines on differential end of axle shaft. Coat seal lip with
wheel bearing grease.
2) Install right axle shaft into axle housing. Ensure axle
shaft engages with side gears in differential.
3) To install left axle shaft, ensure collar is engaged with
splines on intermediate axle shaft. Install left axle shaft into axle
housing. Ensure axle shaft engages with splines on collar. Install
vacuum shift motor, ensuring fork on vacuum shift motor engages groove
on collar. Install and tighten bolts to specification. See TORQUE
SPECIFICATIONS table.
4) To complete installation, reverse removal procedure. Apply
silicone rubber sealant to edge of grease cap before installing.
Tighten bolts/nuts to specification. See TORQUE SPECIFICATIONS table.
DRIVE SHAFT
Removal
1) Raise and support vehicle. Ensure transmission and
transfer selector levers case are in Neutral. Reference mark drive
shaft and pinion flange for reassembly reference.
2) Remove bolts and "U" joint straps at pinion flange. Remove
center carrier bearing bolts (if equipped). Remove drive shaft.
CAUTION: The "U" joint components are not serviceable. Replace
complete assembly. DO NOT reuse.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF SERVICE REQUIREMENTS & SUGGESTIONS
It is MAP policy that all exhaust, brake, steering,
suspension, wheel alignment, drive-line, engine performance and
maintenance, and heating, ventilation and air conditioning, and
electrical services be offered and performed under the standards and
procedures specified in these sections.
Before any service is performed on a vehicle, an inspection
of the appropriate system must be performed. The results of this
inspection must be explained to the customer and documented on an
inspection form. The condition of the vehicle and its components will
indicate what services/part replacements may be "Required" or
"Suggested". In addition, suggestions may be made to satisfy the
requests expressed by the customer.
When a component is suggested or required to be repaired or
replaced, the decision to repair or replace must be made in the
customer's best interest, and at his or her choice given the options
available.
This section lists the various parts and conditions that
indicate a required or suggested service or part replacement.
Although this list is extensive, it is not fully inclusive. In
addition to this list, a technician may make a suggestion. However,
any suggestions must be based on substantial and informed experience,
or the vehicle manufacturer's recommended service interval and must be
documented.
Some conditions indicate that service or part replacement is
required because the part in question is no longer providing the
function for which it is intended, does not meet a vehicle
manufacturer's design specification or is missing.
Example:
An exhaust pipe has corroded severely and has a hole
in it through which exhaust gases are leaking. Replacement
of the exhaust pipe in this case is required due to
functional failure.
Example:
A brake rotor has been worn to the point where it measures
less than the vehicle manufacturer's discard specifications.
Replacement of the rotor is required because it does not meet
design specifications.
Some conditions indicate that a service or part replacement
is suggested because the part is close to the end of its useful life
or addresses a customer's need, convenience or request. If a
customer's vehicle has one of these conditions, the procedure may be
only to suggest service.

is suggested because the part is close to the end of its useful life
or addresses a customer's need, convenience or request. If a
customer's vehicle has one of these conditions, the procedure may be
only to suggest service.
Example:
An exhaust pipe is rusted, corroded or weak, but no leaks are
present. In this case, the exhaust pipe has not failed.
However, there is evidence that the pipe may need replacement
in the near future. Replacement of the pipe may be suggested
for the customer's convenience in avoiding a future problem.
Example:
The customer desires improved ride and/or handling, but the
vehicle's shocks or struts have not failed. In this case,
replacement may be suggested to satisfy the customer's
wishes. In this case, replacement of the shocks or struts may
not be sold as a requirement.
A customer, of course, has the choice of whether or not a
shop will service his or her vehicle. He or she may decide not to
follow some of your suggestions. When a repair is required, a MAP shop
must refuse partial service on that system if, in the judgment of the
service provider, proceeding with the work could create or continue an
unsafe condition. When a procedure states that required or suggested
repair or replacement is recommended, the customer must be informed of
the generally acceptable repair/replacement options whether or not
performed by the shop.

When presenting suggested repairs to the customer, you must
present the facts, allowing the customer to draw their own conclusions
and make an informed decision about how to proceed.
The following reasons may be used for required and suggested
services. These codes are shown in the "Code" column of the MAP
Uniform Inspection & Communications Standards that follow:
Reasons to Require Repair or Replacement
A - Part no longer performs intended purpose
B - Part does not meet a design specification (regardless of
performance)
C - Part is missing
NOTE: When a repair is required, the shop must refuse partial
service to the system in question, if the repair creates
or continues an unsafe condition.
