Explorer 2WD V6-4.0L VIN K (2007)
Axle Shaft Assembly: Description and Operation
Rear Drive Halfshafts
^
The RH and LH halfshafts are different lengths, with the RH halfshaft being the longer of the 2.
^
Inboard and outboard CV joints connect to a splined shaft. A circlip stopper holds the inboard race assembly (inboard CV joint) together.
^
An axle circlip retains the splined inboard CV joint to the differential side gear. Install a new axle circlip every time the halfshaft is removed from
the vehicle.
^
A rear axle wheel end nut secures the side shaft assembly (interconnecting shaft and outboard CV joint) to the rear hub. Install a new rear axle
wheel end nut every time you remove the halfshaft from the vehicle.
^
Install a new differential stub shaft seal every time the halfshaft is removed.
Halfshaft Handling
CAUTION: Never pick up or hold the halfshaft by the inboard or outboard CV joint only.
NOTE: Only the inner CV joints are removable for installation of new CV boots and clamps. The boots and clamps are the only serviced parts of the
halfshaft assembly.
Handle all halfshaft components carefully during removal and installation procedures.
^
The halfshaft assemblies are not repairable. Install new assemblies if worn/damaged.
^
To separate the halfshaft from the rear hub, press the outboard CV joint from the rear hub.
^
To separate the halfshaft from the differential, apply a load to the back face of the inboard CV joint assembly to overcome the axle circlip.
^
Do not overangle the CV joints.
^
Damage will occur to an assembled inboard CV joint if it is overplunged outward from the joint housing.
^
Never use a hammer to remove or install the halfshafts.
^
Never use the halfshaft assembly as a lever to position other components. Always support the free end of the halfshaft.
^
Do not allow the boots to contact sharp edges or hot exhaust components.
^
Handle the halfshaft by the interconnecting shaft only to avoid pull-apart and potential damage to the CV joints.
^
Do not drop assembled halfshafts. The impact can cut the boots from the inside without evidence of external damage.
Wheel and Tire Balancing, Rear
WARNING: Do not balance the rear wheels and tires while mounted on the vehicle.
Hoisting
CAUTION: Use a frame-contact hoist only. Vehicle or component damage can result if other types of hoists are used. For additional
information, refer to Maintenance/Service and Repair.
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.
