General information about the suspension (Chevrolet Tahoe 1)

The steering drive consists of a pendulum arm, a main rod, two adjustable side rods and a shock absorber (on car parts). When the steering wheel is turned, the force is transmitted through the steering gear to the steering knuckle, which causes the main rod to shift. The force is transmitted through the lateral rods and the lever to the steering knuckles and wheels. The rods, steering knuckle and pendulum arm are attached with pins with ball ends. The pendulum arm provides a rigid axis of rotation for the main steering rod. The pendulum arm is attached to the frame. The steering shock absorber is attached to the main rod from the frame side.

The front suspension is independent and consists of two pairs of levers (upper and lower), which are connected to the frame with bolts and to the steering knuckles with ball joints. The elastic element of the suspension on rear-wheel drive models are coil springs, on all-wheel drive models - torsion bars. The damping unit of the front suspension are shock absorbers. Coil springs are inserted into sockets on the frame and on the lower suspension arms. The shock absorbers are attached to the suspension and to the frame bracket with bolts and nuts. The elastic and damping elements of the rear suspension are springs and shock absorbers (see photo).

The rear axle is connected to the springs by U-bolts (U-bolts). The front ends of the springs are connected to the frame with hinges, through rubber bushings. The rear ends of the springs are attached to the frame with shackles, which provide additional travel of the spring when driving.

Steering and suspension bolts and nuts are usually very difficult to unscrew. For this purpose, it is recommended to clean corroded connections with a brush and wet them with a penetrating liquid. Sometimes a threaded connection can be unscrewed by sharp blows of a punch on the nut. When unscrewing, do not use extensions with ratchets to avoid breakage of the ratchet. Using a torch flame is highly inadvisable due to the increased risk of fire or irreversible deformation of suspension parts. Tighten the connections with a torque wrench, which will facilitate subsequent disassembly. In some fasteners, to unscrew a threaded connection, it is recommended to first slightly tighten it.
