Halfshaft Disassembled View (Part 2 Of 2)
Halfshafts, Front Wheel The front wheel drive halfshafts have the following characteristics:
^
The front wheel halfshaft assemblies transmit engine torque from the transaxle to the front wheels.
^
Constant velocity (CV) joints used must be capable of operating at varying angles and provide a means for shaft length changes to allow for
vertical suspension (wheel) travel and engine dynamic movement.
^
Inboard CV joint is a "plunge"-type joint which provides for axial movement to affect shaft length changes.
^
The outboard CV joint is a cage and ball design serviced as an assembly separate from the interconnecting shaft.
^
Outboard CV joint has a higher angle capability than the inboard CV joint to accommodate wheel turning angles.
^
The halfshafts employ constant velocity (CV) joints at both the inboard and outboard ends for vehicle operating smoothness.
^
The CV joints are connected by an interconnecting shaft.
CAUTION: Never hold the halfshaft assembly by the inboard or outboard joint only. The complete halfshaft assembly should be handled by the
interconnecting shaft to avoid pulling apart or damaging the CV joints.
^
The interconnecting shafts (LH and RH) are splined at both ends and are retained in the inboard and outboard CV joints by driveshaft bearing
retainer circlips.
^
The inboard CV joint stub shaft is splined and held in the differential side gear by a driveshaft bearing retainer circlip.
^
Outboard CV joint stub shaft is retained by a front axle wheel hub retainer.
^
CV joints are lubed-for-life with special CV joint grease and require no periodic lubrication.
^
CV joint boots should be periodically inspected and replaced immediately when damage or grease leakage is evident.
^
Continued operation would result in CV joint wear and noise due to contamination or loss of CV joint grease.
^
Halfshaft assemblies rotate at approximately one-third the speed of conventional rear wheel drive driveshafts and do not contribute to rotational
vibration disturbances.
