The rear suspension consists of two trailing arms connected by a crossmember. In front of the V-shaped crossmember is the anti-roll bar, which reduces vehicle body roll during cornering and thereby stabilizes the vehicle. The rear suspension is connected to the body through rubber-metal mounts. Vehicle springing is provided by two coil springs and two shock absorbers. The springs and shock absorbers are mounted separately, which increases the cargo space width.

The paired rear wheel ball bearings require no maintenance or adjustment.

All-wheel drive vehicles have independent rear suspension with paired transverse arms and longitudinal control arms.

A propeller shaft, final drive and two drive shafts are used to transmit torque. Rear suspension geometry can only be measured using optical methods.

CAUTION

Welding and straightening work on load-bearing and guiding rear suspension components is not permitted. Self-locking nuts and bolts/nuts showing signs of corrosion must always be replaced.
