Universal Joints
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.
U-joints are composed of the following:
- Spiders
- Trunnions
- Grease seals
- Needle rollers
- Bearing cups
- Thrust washers
- Snap rings
The U-joint is a method of connecting the driveshaft to the drive axle. A U-joint allows the angles of the output shafts, driveshafts and pinions to rotate smoothly while constantly accelerating and decelerating. The U-joint is lubricated for the life of the vehicle.
