Fig. 4.4. Low friction ball joint: 1 – front upper arm; 2 – low-viscosity ball joint (for front upper control arm); 3 – front lower arm (rear); 4 – steering knuckle; 5 – Low friction rear ball joint (for front lower arm); 6 – Front low friction ball joint (for front lower arm); 7 – front lower arm; 8 – sectional view
A low friction ball joint is used on the front upper and lower control arm(s) steering knuckle to improve steering response and smoothness (Fig. 4.4).
