DESCRIPTION AND OPERATION
Rear Drive Halfshafts
The rear wheel drive halfshaft system consists of and operates as follows:
zHalfshafts (4K138) transmit engine torque from the rear axle housing to the rear wheels.
z Halfshafts rotate at approximately one- third the speed of a driveshaft and do not contribute to
rotational vibration disturbances.
z A constant velocity (CV) joint is a mechanism for transmitting uniform torque and rotary motion
while operating through a range of angles.
z CV joints at both inboard (differential) and outboard (wheel) ends provide operating
smoothness.
z The inboard CV joints are plunge- type joints that provide the axial movement necessary to
affect shaft length changes.
z The outboard CV joints have a higher angle capability than the inboard CV joints to
accommodate suspension travel.
z Inboard and outboard CV joints connect to a splined shaft.
z A driveshaft bearing retainer circlip retains the splined inboard CV joint to the differential side
gear. Install a new circlip every time you remove the halfshaft from the vehicle.
z A rear axle wheel hub retainer secures the interconnecting shaft and outboard CV joint to the
rear hub.
z The lubed-for- life CV joints use special CV joint grease. They require no periodic lubrication.
z To separate the halfshaft from the rear hub, press the outboard CV joint from the rear hub.
z To separate the halfshaft from the differential, apply a load to the back face of the inboard CV
joint assembly to overcome the circlip.
z The halfshaft assemblies are not repairable. Install a new assembly if worn/damaged.

z
Do not drop assembled halfshafts. The impact will cut the boots from the inside without
evidence of external damage.
z Inspect all machined surfaces and splines for damage.
Wheel and Tire Balancing, Rear
WARNING: Do not balance the rear wheels and tires while mounted on the vehicle.
Possible tire disintegration, differential or halfshaft failure can result, causing personal injury
or extensive component damage. Use an off- vehicle wheel and tire balancer only.
Hoisting
CAUTION: Use a frame- contact hoist only. Vehicle or component damage can result if
other types of hoists are used.
Never raise the vehicle using the halfshafts as lift points.
Undercoating and Rustproofing
During undercoating and rustproofing procedures, protect the boots from the coating materials.
Foreign materials on the rubber boots will cause extreme advanced wear. Klj . 3 ba

The vehicle is equipped with a vacuum-
assisted or a hydro-boost power braking system. Refer to
Section 206 - 07 .
The braking system is a front- to-rear split hydraulic system. Refer to Section 206 - 06 .
The front wheel brakes utilize a dual piston brake caliper and disc brake system. Refer to Section 206 -
03 .
The rear brakes utilize a single piston brake caliper and disc brake system. Refer to Section 206 - 04 .
The parking brake system is a mechanical system that is controlled by an independent hand- operated
parking brake control and is self- adjusting. Refer to Section 206 - 05 .
A 4- wheel anti- lock brake system or anti-lock brake system with traction control (4WABS) is optional
equipment on all models except Cobra. Cobra has ABS and traction control as standard equipment.

DIAGNOSIS AND TESTING
Brake System
Refer to Wiring Diagrams Cell
60 , Instrument Cluster for schematic and connector information.
Refer to Wiring Diagrams Cell 97 , Daytime Running Lamps for schematic and connector information.
Inspection and Verification WARNING: Use of any other than the approved DOT 3 brake fluid will cause permanent
damage to brake components and will render the brakes inoperative.
WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with
eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with
running water for 15 minutes. Get medical attention if irritation persists. If taken internally,
drink water and induce vomiting. Get medical attention immediately.
CAUTION: Do not spill brake fluid onto painted surfaces. If spilled, wipe up immediately.
NOTE: Always check the fluid level in the brake master cylinder reservoir (2K478) before performing
the test procedures. If the fluid level is not at the correct level, add High Performance DOT 3 Brake
Fluid C6AZ- 19542-AB or equivalent DOT 3 fluid meeting Ford specification ESA- M6C25-A.
NOTE: Prior to performing any diagnosis, make sure the brake warning indicator is functional. For
additional information, refer to Section 413 - 01 .
The first indication that something may be wrong in the brake system is a change in the feeling through
the brake pedal (2455). The brake warning indicator in the instrument cluster and the brake fluid level SECTION 206-
