Cleaning and checking
1. Remove the hitch ball joint cover.
2. Remove the ball joint from the vehicle.
3. Visually inspect the ball head (1) and support (2). If the support is dirty, clean it with a jet of steam and dry it with air. Clean the ball head with water and a brush and wipe it with a dry cloth.
Caution: Do not use steam or any solvent such as gasoline to clean the ball head.
4. Measure the diameter of the connecting element ball (3). If the diameter is less than 39 mm, replace the ball head.
Checking the work
1. Visually check the ball head for mechanical damage.
2. Pull the handle and turn it to the "rot" (red) position so that the handle is locked.
