Freestar V6-4.2L VIN 2 (2004)
Differential Assembly: Description and Operation
Driveline System
The drivetrain's power is generated by the engine and delivered to the transmission. The halfshafts transfer the engine torque from the transmission to
the drive wheels.
The front halfshafts have the following characteristics.
^
Halfshaft assemblies are not repairable and must be replaced if worn or damaged.
^
Inboard and outboard CV joints are connected to a splined shaft. Driveshaft bearing retainer circlips retain the CV joints to the splined shafts.
^
On the RH side, a driveshaft bearing retainer circlip retains the splined inboard CV Joint to the differential side gear. Install a new circlip every
time the halfshaft is separated from the differential side gear.
^
A front axle wheel hub retainer secures the splined outboard CV joint to the wheel hub.
^
The lube-for-life CV joints use special CV joint grease. They require no periodic lubrication.
CAUTION: Never pick up or hold the halfshaft only by the inboard or outboard CV joint.
Handle all halfshaft components carefully during removal and installation.
^
Do not over-angle the CV joints.
^
Damage will occur to an assembled inboard CV joint if it is over-plunged outward from the joint housing.
^
Never use a hammer to remove or install the halfshafts.
^
Do not allow the boots to contact sharp edges or hot exhaust components.
^
Never use the halfshaft assembly as a lever to position other components. Always support the free end of the halfshaft.
^
Handle the halfshaft only by the interconnecting shaft to avoid pull-apart and potential damage to the CV joints.
^
Do not drop the assembled halfshafts. The impact will cut the boots from the inside without evidence of external damage.
^
Do not remove the outer CV Joint by pulling on the interconnecting shaft.
^
Inspect all machined surfaces and splines for damage.
^
Never raise the vehicle using the halfshafts as lift points.
^
Never tow a vehicle using the halfshaft as anchor points for tow truck cable or chains.
^
Protect the boots from undercoating and rustproofing materials. Foreign materials on the boots will cause extreme advanced wear.
