Rear Drive Halfshafts
Overview
Rear Drive Halfshafts
The rear drive 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 halfshafts are splined on the inboard stub shaft and retained by circlips. New circlips must be installed whenever they are removed.
CV Joint
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 joints mate the interconnecting shaft with the stub shafts. The joints allow 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.
Halfshaft joints are only serviced as assemblies.
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 by the inboard or outboard CV joint.
- 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 from the rear 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 the joints of the halfshaft results 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 cuts 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.
