Introduction： 3PCS Air Suspension Spring Bags Compressor Pump For Lincoln Navigator AWD 98-02 Introduction： Two front Air Suspesnion shock absorbers are connected from the front suspension to the chassis, and two rear Air Suspension shock absorbers are attached between the rear suspension and the chassis. Shock absorbers have three main purposes: 1. They control spring action and oscillations to provide the desired ride quality. 2. They help prevent body sway and lean while cornering. 3. They reduce the tendency of a tire tread to lift off the road, which improves tire life, traction, and directional stability. Because Air suspension shock absorbers control spring action, spring oscillations, and chassis oscillations, they contribute to vehicle safety and passenger comfort. If the shock absorbers are worn out, excessive chassis oscillations may occur, particularly on rough road surfaces. Th ese excessive chassis oscillations may result in loss of steering control. Worn-out shock absorbers also cause excessive body lean and sway while cornering, which may cause the driver to lose control of the vehicle. Shock absorbers are extremely important to providing longer tire life and improving vehicle handling, steering quality, and ride quality. Air suspension Shock absorber design is matched to the defl ection rate of the coil spring to control the spring action. Several diff erent types of shock absorbers are available for special service requirements.

Recommended replacement cycle: Since the average annual distance of the car is 20,000 kilometers, the replacement frequency is obtained every 4 years or 80.000km. In fact, the replacement frequency will vary depending on the car condition, road condition and shock absorber manufacturer.When driving a certain number of kilometers, we should take corresponding measures to ensure our driving safety. 20.000km: Please check your air suspension 80.000km: Need to replace your air suspension 100.000km: Please replace your air suspension as soon as possible OEM Part Number: Rear air spring 3U2Z5580LA F75Z5A891BA Air Compressor 6L1Z5319AA 1L1Z5319AA 1L1Z5319BA 6L143B484AA 4L1Z5319BB, 5L1Z5319AA 4J1005C Air Suspension Shock Absorber Operation: Air Suspension Shock absorbers are usually mounted between the lower control arms and the chassis. When a vehicle wheel strikes a bump, the wheel and suspension move upward in relation to the chassis. Upward wheel movement is referred to as jounce travel. Th is jounce action causes the spring to deflect or compress. Under this condition, the spring stores energy and springs back downward with all the energy absorbed when it defl ected upward. Th is downward spring and wheel action is called rebound travel. If this spring action were not controlled, the wheel would strike the road with a strong downward force, and the wheel jounce would occur again. Th erefore, some device must be installed to control the spring action, or the wheelwould bounce up and down many times after it hit a bump, causing passenger discomfort, directional instability, and suspension component wear. Shock absorbers are installed on suspension systems to control spring action. When a wheel strikes a bump and jounce travel occurs, the shock absorber lower tube unit is forced upward. Th is action forces the piston downward in the lower tube unit. Since oil cannot leak past the piston, the oil in the lower unit is forced through the piston orifi ces or valves to the upper oil chamber. These valves provide precise oil fl ow control and control the upward action of the wheel and suspension, which is referred to as a shock absorber compression stroke (Figure 5-2). When the spring expands downward in rebound travel, the lower shock absorber unit is also forced downward. When this occurs, the piston moves upward in the lower tube unit, and hydraulic oil is forced through the piston orifi ces or valves from the upper oil chamber to the lower oil chamber. Since the valves restrict oil flow with precise control, the downward suspension and wheel movement is controlled. When the shock absorber piston moves, oil is forced through the piston. Since the piston valves and orifi ces resist the fl ow of oil, friction and heat are created. Th e resistance of the oil moving through the piston must be calibrated as closely as possible to the spring’s deflection rate or strength. Wheels and suspension systems defl ect at many diff erent speeds, depending on the type and size of bump and the vehicle speed. Th e resistance of a shock absorber piston increases with the square of its speed. For example, if the wheel defl ection speed increases four times, the piston resistance is sixteen times as great. Th erefore, if a wheel strikes a large bump at high speed, the wheel defl ection and rebound can be eff ectively locked by the shock absorber. Shock absorber engineers prevent this action by precisely designing shock absorbervalves and orifi ces to provide enough friction to prevent the spring from overextending on the rebound stroke. Th ese piston valves and orifi ces must not create excessive friction, which slows the wheel from returning to its original position. Shock absorber pistons have many diff erent types of valves and orifi ces. In some pistons, small orifi ces control the oil flow during slow wheel and suspension movements. Stacked steel valves control the oil fl ow during medium speed wheel and suspension movements. During maximum wheel and suspension movements, larger orifi ces between the piston valves provide oil fl ow control. On other shock absorber pistons, the stacked steel valves alone provide oil flow control. Regardless of the piston orifi ce and valve design, the shock absorber must be precisely matched to absorb the spring’s energy. During fast upward wheel movement on the compression stroke, excessive pressure in the lower oil chamber forces the base valve open and thus allows oil to fl ow through this valve to the reservoir. Th e nitrogen gas provides a compensating space for the oil that is displaced into the reservoir on the compression stroke and when the oil is heated. Since the gas exerts pressure on the oil, cavitation, or foaming of the oil, is eliminated. When oil bubbles are eliminated in this way, the shock absorber provides continuous damping for wheel defl ections as small as 0.078 in (2.0 mm). A rebound rubber is located on top of the piston. If the wheel drops downward into a hole, the shock absorber may become fully extended. Under this condition, the rebound rubber provides a cushioning action. Package Includes: 3PCS for Rear Left & Right Air Suspension Spring Bags&Air Suspension Compressor Notes : Of all the suspension components, shock absorbers and struts contribute the most to ride quality. As the vehicle is driven over road irregularities, the shock absorbers or struts are continually operating to control the spring action and provide acceptable ride quality. It has been my experience that shock absorbers and struts usually wear out fi rst in suspension systems, because they are working every time a wheel strikes a road irregularity. Th erefore, you must understand not only shock absorber and strut operation but also how ride quality is aff ected if these componen Please double confirm the compatibility as well as the OEM number before purchasing.
