Rear Drive Halfshafts: Notes
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The outboard CV joint shaft assembly should not be disassembled.
NOTE:
Due to the sub-assembly process, if the outboard CV boot needs replacement, the inboard CV boot must also be replaced. However, the inboard CV boot can be replaced by itself.
The rear drive halfshafts consist of the following:
- Inner CV joints
- Outer CV joints
- Interconnecting shafts
- Convoluted CV joint boots
- CV joint boot clamps
- Special CV high-temperature grease
- CV joint housings
- Ball and cage housings
- A circlip stopper that holds the cross-groove inboard race assembly (inboard CV joint) together
- A circlip that retains the splined inboard CV joint to the differential side gear
- The RH and LH halfshafts are different lengths, with the LH halfshaft being the longer of the 2.
The rear drive halfshafts link the rear axle to the rear wheel hubs. The CV joints allow the halfshafts to rotate smoothly through the required changes in angles between the stationary axle and the varying angles of the front wheels including jounce and rebound plus changes while turning. The CV joints are caged ball type. New halfshaft components are available as kits containing grease, boots and clamps.
