Checking the ball joints of the steering rods (VAZ-21051)

1. First of all, check the movement of the rod ends along the axis of the pins. To do this, using a lever and support, move the end parallel to the axis of the pin.

2. The axial movement of the tip relative to the pin should be 1–1.5 mm. Such movement indicates that the pin insert is not jammed in the rod tip socket and moves together with the pin, compressing the spring. Replace the joint with the jammed insert.

3. While rocking the steering wheel in both directions, feel for any free play in the tie rod joints. If there is free play in the ball joint, replace the tie rod end or the tie rod assembly.

4. Check the condition of the protective rubber caps of the ball joints of the steering rods. The cap must be replaced if it has cracks, tears or separation of the rubber from the edging, and also if grease penetrates out when squeezed by hand.

5. If the protective caps are in good condition and keep the inside of the joints clean, the service life of the latter is practically unlimited. If moisture, dust, etc. gets into the joint, its parts wear out prematurely.

6. The cap must be replaced if it has cracks, tears, or if grease leaks out when squeezed with your fingers.
