AXLE SHAFT S - FRONT
1988-93 Drive Axles - FWD Axle Shafts
DESCRIPTION & OPERATION
Axle shafts transfer power from transaxle to driving wheels. All axle shafts consist of a shaft with a flexible Constant Velocity (CV) joint at
each end. Inner CV joint is coupled to transaxle by splines. Outer CV joint is splined to hub assembly and secured by axle shaft nut.
Three different types of axle shaft CV joints are used: Double Offset Joint (DOJ) or Rzeppa type, Birfield Joint (BJ) and the Tripot Joint (TJ).
CV joint boots protect CV joints by maintaining proper lubrication and preventing contaminants from entering joint. Boots must be replaced
when signs of leakage or cracks are present. Inner CV joint may be disassembled and serviced. Outer CV joint boot may be replaced, but outer
Birfield CV joint must NOT be disassembled. It must be replaced as an assembly, if faulty.
To prevent torsional vibration and torque steer on turbocharged Capri vehicles, an intermediate shaft and conventional axle shaft are used on
the right side. Both shafts are of similar length and are supported by a bearing, which is attached to engine.

SOLENOID TEST
Disconnect wiring and cables from solenoid. Using an ohmmeter, check for continuity between terminal "M" and body of starter solenoid. See
Fig. 1
. Continuity should exist. If continuity does not exist, replace solenoid.
ARMATURE TEST
1. Place armature in growler. Turn on growler and hold a piece of hacksaw blade over armature. Slowly rotate armature. If hacksaw blade
is attracted to core or if it vibrates, replace armature.
2. Remove armature from growler. Using an ohmmeter, check continuity between commutator and core. If continuity exists, replace
armature. Check continuity between commutator and shaft. If continuity exists, replace armature.
3. Check continuity between each commutator segment. If an open exists between any 2 segments, replace armature.
COMMUTATOR TEST
1. Clean surface of commutator and polish with No. 400 grit sandpaper (if required). If surface is scored, out of round or pitted, turn
commutator on a lathe.
2. Maximum commutator runout and minimum diameter of commutator must not exceed specification after turning. See STARTER
MOTOR SPECIFICATIONS table.

GENERAL INFORMATION
Using Mitchell1's Wiring Diagram s
INTRODUCTION
Mitchell1(R) obtains wiring diagrams and technical service bulletins, containing wiring diagram changes, from the domestic and import
manufacturers. These are checked for accuracy and are all redrawn into a consistent format for easy use. All system wiring diagrams are
available in color format and may be viewed and or printed in color or black and white, depending on your program settings and available
printer hardware.
In the past, when cars were simpler, diagrams were simpler. All components were connected by wires, and diagrams seldom exceeded 4 pages
in length. Today, some wiring diagrams require more than 16 pages. It would be impractical to expect a service technician to trace a wire from
page 1 across every page to page 16.
Removing some of the wiring maze reduces eyestrain and time wasted searching across several pages. Today, the majority of Mitchell1(R)
diagrams follow a much improved format, which permits space for internal switch details, and component and ground locations.
Components shown with a dashed line instead of a solid line indicate not all circuits are shown in this particular diagram (circuits shown in
system diagrams are typically applicable to that system only). The remaining circuits connected to that component will be shown in the
appropriate system that they apply to.
Today, the wiring diagram necessary to support a given repair procedure is included within that article or a link is provided to the appropriate
SYSTEM WIRING DIAGRAM article. For example, the wiring diagram for a Ford EEC-IV system may be included in ENGINE
PERFORMANCE and WIRING DIAGRAMS articles for Ford Motor Co. The wiring diagram for a cruise control system may be included in
ACCESSORIES & EQUIPMENT section for the specific vehicle manufacturer, and the wiring diagram for an anti-lock brake system may be
included in BRAKES and WIRING DIAGRAMS for the specific manufacturer.
WIRING DIAGRAMS contains all wiring diagrams not included in STARTING & CHARGING SYSTEMS and ACCESSORIES &
EQUIPMENT. This includes: Data Link Connectors, Ground Distribution, Power Distribution, Engine Performance, Electric Cooling Fans,
Anti-Lock Brakes, Electronic Suspension and Electronic Steering wiring diagrams. The Data Link Connectors wiring diagrams show the
circuits by which the various on-board computers exchange information, and the diagnostic connectors used for diagnosis and their location.
The Ground Distribution wiring diagrams show all vehicle ground points, their location, and the components common to those ground points.
The Power Distribution wiring diagrams show the power feed circuits and the components common to those power feeds.
Wiring diagrams used to support the information in ACCESSORIES & EQUIPMENT are drawn in a "top-down" format. The diagrams are
drawn with the power source at the top of the diagram and the ground point at the bottom of the diagram. Component locations are identified
on the wiring diagrams. Any wires that do not connect directly to a component are identified on the diagram to indicate where they go.
