Axle Joints: Checking Dust Boots
WARNING: This page is about a different car, the 2020 Porsche Cayenne and 2019 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
- Visually inspect the dust boots for damage.
Information
- When doing so, the rubber dust boots should be pressed down with the fingers to reveal hidden cracks.
- If a rubber dust boot leaks, the corresponding joint or control arm must be replaced, because any dirt or moisture that seeps in will destroy the joint.
- Inspect the dust boots of the axle joints on the wheel suspension (front and rear) as follows:
- Move the vehicle onto a lifting platform with the steering lock disengaged.
- Perform a visual inspection after cleaning.
Information
- Over a small area in the vicinity of the brake cover panels, no visual inspection is possible.
- Check this area by touch.
The procedure for the front axle is as follows:
- Turn the front wheels as far as they will go.
- Visually inspect the visible surfaces on the left and right.
- After turning the front wheels to the other steering stop, check the other half of each rubber dust boot.
