Shock absorber NTY AUDI A7

Choosing these parts, you should always consider the vehicle’s operating conditions and recommendations of its manufacturer. Oil shock absorbers are cheap. They ensure comfort when driving at low speed but are prone to overheating under high loads.

Gas components are stiffer. They help to improve the handling of the car and prevent the body from rocking. Their gas chamber is filled with nitrogen, which prevents the oil from foaming. Such parts perfectly absorb vibrations that occur when driving at high speed. At the same time, they ensure a smooth ride.

Gas shock absorbers are perfect for high-performance sports cars. They withstand maximum loads and are well cooled. These components increase suspension stiffness, which positively affects car manoeuvrability and handling. However, they don’t ensure enough comfort.

Visually inspect the parts to determine their condition. Oil leaks, dents on the housing, corrosion and deformation of the piston rod indicate the defective components. If there are no obvious signs of faulty shock absorbers, their malfunction can only be detected on a specially designed test bench at a garage.

Check the parts if you noticed:

• increased braking path;
• significant car body sway at sharp braking or driving on bumpy roads;
• slow steering response;
• accelerated tyre wear;
• knocking in the suspension when driving on poor-quality roads.

For replacement, you will need the following items:

• a lifting device;
• a set of hand tools: spanners, drive sockets, a hammer, screwdrivers, and pliers;
• a WD-40 spray to make it easier to unscrew the stuck fasteners.

The components replacement procedure is rather complicated and time-consuming. You can find a detailed algorithm in your car owner’s manual. Remember that these parts should be replaced in pairs on one axle. Pump them before installing.

To access the upper mount and fasteners, you often need to remove the engine compartment seal or the luggage compartment trim panel. While the wheels and brake discs hinder the access to the lower mount and fasteners. For replacement of the shock absorbers, you will also have to remove the suspension arm ball joint, tie rod and disconnect the stabiliser link. The demounted unit should be carefully supported in order to avoid injuries. Always use special compressor tools when working with springs.
