About part number LR142074

A front right-hand side air strut shock absorber is a combined suspension unit that combines an air spring with a hydraulic damper. Sitting between the vehicle chassis and the wheel assembly on the front right-hand side, it holds up the weight of the vehicle using compressed air while controlling movement over bumps. When it is working correctly, the vehicle sits level, handles predictably, and provides a smooth ride without excessive bouncing or sag.

To confirm that this part is correct for your vehicle, match the part number directly. The manufacturer part number for this item is LR142074. You may also find the numbers MY42-3C285-AB, MY423C285AB, or MY42-18045-AA stamped into the metal casing or printed on a label on the original unit. Matching these exact reference numbers is what determines correct fitment.

These units are usually replaced when the internal rubber air bag perishes and leaks air, or when the hydraulic damper begins to leak oil and lose efficiency. When fitting a replacement air strut, it is common practice to replace the rubber sealing rings and check the condition of the air line connections to prevent air leaks.

About this kind of part: shock absorbers and struts

A shock absorber damps the movement of a spring. A strut is a shock absorber that also locates the wheel, so it carries the spring, the top mount and often the brake hose and sensor brackets as well. On a car with adaptive suspension the damper holds a valve the car controls electrically and has a connector on it; on one with air suspension the spring is a rubber bellows with its own air line. These three kinds share a name and nothing else, and they are not interchangeable.

Why people replace one

  • The car floats or pitches after a bump, or the nose dives further than it used to under braking.
  • The damper is wet with oil down its body, which means the seal has gone and it has lost its fluid.
  • A knock from the top of the suspension over small bumps, which is usually the top mount or its bearing rather than the damper.
  • An inspection has advised on a leaking damper or on uneven damping across an axle.
  • On air suspension, the car settles overnight or will not raise, and a bellows has perished or an electrical damper has failed.
  • Tyres are scalloped or cupped across the tread, which is a damper no longer controlling the wheel.

Fitting it

  • Dampers are replaced in pairs across an axle. One new and one worn gives the car different damping on each side, which is worse than two worn ones.
  • A strut assembly holds a compressed spring. It must only be taken apart with a proper spring compressor, and a coil spring under compression will injure somebody if it escapes.
  • The top mount, its bearing and the bump stop are separate parts and are normally replaced at the same time, because they have done the same mileage.
  • An electrical damper usually needs no coding, but an air strut generally needs the system calibrating and the ride height set afterwards.
  • The car needs its alignment checked afterwards where a strut locates the wheel.
  • This is a safety-critical part of the car. If there is any doubt, have it fitted by a workshop.

Making sure it is the right one

  • Match the part number, and buy in pairs. Within one model there are commonly a standard, a sports and a self-levelling version, and the car was built with one of them.
  • Check which kind you have: a plain damper, an electrically adjustable one with a connector, or an air strut with an air line. Count the connector pins if there is one.
  • Check what is included. A bare damper, a damper with a spring, and a complete strut with the top mount fitted are three different things to buy.
  • Compare the brackets on the body. The mounts for the brake hose, the sensor lead and the anti-roll bar differ between versions and are what tells them apart.

What to look for in the photographs

A Part number — On a label or stamped into the body of the damper, often near the lower mount.
B Connector or air line — Whether the unit is electrically adjustable or air-sprung. This is the first thing to match, because the three kinds share nothing but a name.
C Damper body — Look down the body for oil, which means the seal has gone, and for pitting on the exposed rod.
D Top mount and bearing — Whether they are included and the state of the rubber. They have done the same mileage as the damper.
E Brackets — The mounts for the brake hose, the sensor lead and the anti-roll bar. These differ between versions and are how you tell them apart.
F Lower mount — The eye or fork at the bottom and the state of its bush. Compare the width and the bolt diameter with your own.
