NOTE: Mark the new cam bolt in the same position as the old one for assembly reference
before discarding the old bolt.
Disconnect the knuckle from upper suspension arm and bushing. 1. Remove and discard the nut and bolt.
2. Disconnect the knuckle from the upper suspension arm and bushing.
18. CAUTION: The crown on the tool forks must face away from the differential
housing. Position the special tool correctly between the CV joint and the differential
housing so as not to damage the differential seal.
Using the special tool, exert enough pressure to overcome the circlip and separate the CV joint
from the differential side gear.
19. Install the special tool.
20. Remove the halfshaft and knuckle assembly from the vehicle. Klj . 5 ba

14.
CAUTION: Install the hardened washer between the lower suspension arm and
bushing and the shock absorber. Failure to do so can result in damage and failure of the
lower suspension arm and bushing.
Position the shock absorber, and install the bolt and the new nut.
15. Install the other halfshaft and knuckle assembly, toe link, and shock absorber as described in the previous steps.
16. Raise the suspension until the shock absorbers compress to the previously established alignment mark (curb height).
17. Tighten the nut. Klj . 11 ba

18. Align the marks on the cam bolt and the upper suspension arm and bushing, and tighten the
nut.
19. Repeat the two previous steps for the other knuckle.
20. Lower the suspension and remove the jack stands.
21. Apply Anti- Seize Lubricant to the rear brake anti- lock sensors where they contact the axle
housing and install the anti- lock sensors.
z Use High Temperature Nickel Anti- Seize Lubricant F6AZ-9L494-AA or equivalent
meeting Ford specification ESE- M12A4-A.
22. Install the brake disc, and the rear disc brake caliper and support bracket assembly. For additional information, refer to Section 206 - 04 .

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.
