Inner Universal Joint

INNER UNIVERSAL JOINT
The inner universal joint consists of a driver journalled in a ball bearing in the differential bearing housing and splined into the differential wheel. The driver is locked axially by a circlip on the inside of the ball bearing, and by a spring and plunger at the driver end resting on the differential shaft.

The driver can be removed from the gearbox together with the differential bearing seat.

The outside of the driver is in the form of a sleeve which is slotted for the three-bearing universal joint of the inner drive shaft. When the car is travelling, the universal joint, which is equipped with needle bearings, can slide axially in the driver cup, and its angle in relation to the axis of the driver is also free to change. The universal joint is packed with grease and is protected by a rubber gaiter. Greasing of the universal joint need only be carried out after overhaul or if the universal joint is dismantled for any other reason.
