DESCRIPTION AND OPERATION

Front Drive Halfshafts

The halfshafts consist of the following components:

  • Inner CV joints
  • Outer CV joints
  • Interconnecting shafts

The halfshafts are splined on the outboard stub shaft to drive the wheel hubs. They are retained in the wheel hubs by special wheel hub nuts which also control the wheel bearing preload. The LH halfshaft is splined on the inboard stub shaft and is retained in the differential side gear in the transaxle by a circlip. The circlips must be installed new whenever they are removed. The RH halfshaft is retained in the transaxle differential side gear by bolts that go through the intermediate shaft support bearing. The intermediate shaft also goes through the Power Transfer Unit (PTU) on All-Wheel Drive (AWD) vehicles. The outer seal of the PTU must be installed new whenever the RH halfshaft is removed.

Halfshaft Joint

The front drive halfshaft CV joints consist of the following components:

  • CV joint boot clamps
  • Convoluted CV joint boots
  • Tripod joint housings
  • Ball and cage housings
  • Retainer circlips
  • Special CV high-temperature grease

The CV joint mates the interconnecting shaft with the stub shaft. The joint allows for smooth rotation of the interconnecting shaft and the stub shafts. They also adjust for length variances and angle requirements as the vehicle goes through jounce and rebound.

The halfshaft joints are not repairable and are serviced as assemblies only.

Halfshaft Handling

Handle all halfshaft components carefully during removal and installation and during various component disassembly and assembly procedures.

  • Never pick up or hold the halfshaft only by the inboard or outboard CV joint.
  • 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.
  • Excessive pulling force on the interconnecting shaft between joints of the halfshaft will result in internal joint damage. Axial loads used in assisting removal must be applied through the inboard joint housing only.
  • 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.
  • Do not allow the ball joint stud to contact the CV joint boot when disconnecting the lower arm.

  1. NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part number or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

    NOTICE: Use care when releasing the lower arm and knuckle into the resting position or damage to the ball joint seal or Constant Velocity (CV) boot may occur.

    NOTE: Use the hex-holding feature to prevent the stud from turning while removing the nut.

    Discard the specified component. Follow local disposal regulations.

  1. NOTICE: The wheel hub nut contains a one-time locking chemical that is activated by the heat created when it is tightened. Install and tighten the new wheel hub nut to specification within 5 minutes of starting it on the threads. Always install a new wheel hub nut after loosening or when not tightened within the specified time or damage to the components can occur.
