Pic. 7.7. Ball joint: 1, 4 - self-locking nut; 2 - lower transverse lever; 3 – mud-protective cover; 5 – rotary fist; 6 - ball joint
ball joints (right and left between wishbone and hub housing) installed in plastic bushings with long-term lubrication (pic. 7.7). Plastic covers protect them from dirt and moisture. Ball joints do not require maintenance. A damaged mudguard means the hinge needs to be replaced. Failure to detect damage to the mudguard means premature replacement of the otherwise maintenance-free hinge.
Sequence of work
1. Turn the wheels all the way to the appropriate side.
2. Check the hinge dust cover on the right and left for damage. At the same time, it should be compressed - this is how hidden cracks can be detected.
3. A damaged dust cover cannot be replaced separately. The ball joint is replaced as an assembly.
