Abstract: An insulator block (10) for use with vehicle suspension systems particularly camel-back truck suspension systems. The insulator block (10) comprises a resilient base (12), locating pin (13) and a ring (14) with an eccentric aperture (15). The eccentric aperture (15) receives locating pin (13) the outer circumference of ring (14) mates with an aperture in the leaf spring of the suspension system. The insulator block (10) connects the leaf spring of the suspension system to the drive axle of the vehicle via a hollow box unit (5). The position of the hollow box unit (5) and vehicle axle to the leaf spring may be adjusted by using rings (14) with different eccentric apertures (15) on the locating pin (13). The rings (14) are normally held in place on the locating pin (13) by tack or spot welding.

Abstract: A camber adjusting system for use on the steerable wheels in a closed knuckle steering system comprises eccentrically mounting the steering knuckle relative to the axle tube such that the camber angle of the steering knuckle is adjustable by rotation of the eccentric mounting between the knuckle and the axle tube until the desired camber angle is achieved.
