Swinging Force

WARNING: This page is about a different car, the 2005 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before checking the axial forces and end play, turn the lower ball joint at least 10 revolutions so that the ball joint is properly broken in.

Measure the ball joint swinging force using a suitable tool.
- Measure at the cotter pin hole for upper ball joint as shown.
- Measure at the groove for lower ball joint as shown.
