Careless driving and dirt accumulation greatly increase the risk of wear on safety-relevant chassis and steering components. Workshops need to pay attention to typical damage patterns and remedy defects as required. If chassis or steering components are damaged, the person steering needs to expect handling of their vehicle to be critical. Experts at ZF Aftermarket therefore advise workshops to inform their customers of how important regular inspections are. Many components may be affected.
Damage to sealing boot at the tie rod end caused by contact with brake fluid or engine oil.
Mechanics should particularly check whether the rubber bellows on the joints are worn, damaged or leaking. Because any splash water that gets in washes out the special grease and this then allows dirt particles to enter the joint. These particles destroy the inner plastic spherical shell and damage both the ball stud and the joint housing. This means that the clearance in the joint no longer meets the standard. In the steering, the tie rod requires special attention: Apart from the rubber bellows, the steering boot needs to be checked for damage. The spring clamping rings should also be looked at so that any spots of rust are already identified as soon as they appear.
Snap ring rupture caused by rust after damage to the rust protection layer during installation.
On the chassis the supporting joint, control arms and the stabilizer can show serious damage caused by corrosion, intruded foreign matter or dirt accumulation. In addition, driving over curbs is often the cause of defects. The consequences of damage greatly impair the vehicle handling and, thus, safety. Apart from that, they often lead to increased wear on other chassis components as well as tires wearing unevenly and worse riding comfort. This means higher risk of accidents and additional repair expenses.
