Axle Shaft Assembly: Description and Operation
Front Drive Halfshafts
-
Inboard and outboard constant velocity (CV) joints connect to a splined shaft. Driveshaft bearing retainer circlips retain the CV joints to the
splined shaft.
-
On the LH side, the inboard CV joint is retained in the differential side gear with a 33 mm (1.29 inch) retainer circlip. Install a new circlip every
time the halfshaft is disconnected.
-
On the RH side, a 30 mm (1.181 inch) driveshaft bearing retainer circlip retains the splined inboard CV joint to the intermediate shaft. Install a
new circlip every time you disconnect the halfshaft from the intermediate shaft.
-
A front axle wheel hub retainer secures the splined outboard CV joint to the wheel hub.
-
The lubed-for-life CV joints use special CV joint grease. They require no periodic lubrication.
-
The halfshafts are not serviceable. If worn or damaged, install new.
Halfshaft Handling
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 and during various component disassembly and assembly procedures.
-
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 from the front hub.
-
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 only by the interconnecting shaft to avoid pull-apart and potential damage to the CV joints.
-
Do not drop 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.
Wheel and Tire Balancing, Rear
WARNING: Do not balance the front 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.
Towing
Never tow a vehicle using the halfshafts as anchor points for tow truck cable or chains. Refer to the Towing Manual for correct procedures.
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.
