The front suspension load-bearing element is the aggregate beam, fixed to the body, so that the aggregate beam can be removed together with the engine and gearbox. This is required in extremely rare cases of repair. The front wheels are independently suspended on shock absorber struts. The shock absorber struts are screwed to the body at the top and connected to the aggregate beam at the bottom via hubs and transverse levers. The wheels have radial-thrust ball bearings. The transmission of driving torque from the engine occurs through drive shafts connected to the wheels and gearbox via constant velocity joints

Attention: Welding and straightening work on load-bearing and wheel-driven parts is prohibited.


The figure shows the suspension of a front-wheel drive vehicle with mechanical steering.

When pressing out of the steering knuckle, do not spread the spline on the steering knuckle. After installation, adjust the camber. Trunnion diameter = 17 mm. with a forged steering knuckle: diameter = 19 mm.
