Air Spring, Rear

Vehicle damage and personal injuries will be prevented by checking that the air spring has no pressure remaining before removal. High-pressure venting occurs when disconnecting an air line from the compressor because this creates unsafe conditions which may harm users and their surroundings. The inflation or installation of any folded rear air spring will trigger fast system or air spring failure. After installation, any unfolded rear spring needs refolding but this procedure works only on air springs that did not support vehicle weight while folded incorrectly. The inspection detects improper air spring folds and requires air springs as replacements. It is unsafe to inflate any air spring which collapsed from its normal position because it leads to the jounce stop therefore airing inflation is forbidden. New air springs require the air spring fill process before suspension loading can start and the air spring should undergo shape inspection after inflation. The service technician needs to position the vehicle on the lifting device while turning off the air suspension switch located on the left-hand side of the luggage compartment before proceeding with deflation. Lift the vehicle before you remove its rear air spring retainer and raise the bottom section off the rear axle to detach it. The vehicle requires an electrical connector disconnection followed by pushing the red air line retaining ring then disconnecting the air line. When installing the suspension do not allow compression to occur before air spring inflation. Apply the air spring assembly into its frame seat and fasten the spring retainer clip before setting the air spring bottom onto the rear axle. The installation requires a full insertion of the white air line into its fitting so that proper attachment is achieved. Secure the electrical connector while connecting the air line to the proper shape of air spring without folds or creases before refilling the air springs.

First service and repair of air spring requires users to verify that all pressure is removed because handling an uncompressed air spring under pressure may result in vehicle or personal injury. High-pressure air will release unpredictably when you disconnect an air line from the air compressor which could cause personal injury together with damage to the components. The installation of unfolded rear air springs is prohibited and any unfolded springs require previous weight-bearing condition check to merge before usage. Replacement of all improperly folded air springs becomes necessary when they appear during pre-delivery inspection or after vehicle usage. The inflation of collapsed air springs is prohibited when they move from the rebound hanging position to the jounce stop. A new air spring requires inflation by using the air spring fill procedure before the suspension system can be loaded and a proper air spring shape must be checked after inflation. The air suspension system must be vented before applying any lifting operations to the vehicle on an appropriate lifting device. The air suspension system power needs to be disabled through the air suspension switch which is positioned on the LH side of the luggage compartment. The worker should first raise and support the vehicle and then remove the rear air spring retainer before lifting the air spring base from the rear axle. You should disconnect the electrical connector before compressing the quick connect locking ring to pull the air line out of the air spring for complete removal. During installation it is essential not to compress the suspension first since this method would result in damage to the air spring. The white air line requires a full insertion into the fitting throughout the installation process. Mount the air spring assembly into the frame seat while installing the retainer clip then place the bottom of the air spring onto the rear axle. You must reattach the electrical connector alongside the air line to connect the air spring solenoid valve while also setting its correct shape and performing air spring refilling.

Every air spring servicing operation requires no residual pressure to protect both the vehicle structure and prevent occupational injuries. The release of uncontrolled high-pressure air through an air line disconnected from an air compressor results in potential injuries as well as damage. A refolding operation exists exclusively for air springs without weight-bearing experience of improper folding and must be executed before installation. The product replacement rule applies to all folded air springs which appear faulty during the pre-delivery inspection or after normal use. The inflation of an air spring should never occur when it collapses into the jounce stop from the rebound hanging position. The suspension installation process must not apply weight until new air springs receive proper inflation. Check the air spring form after performing air inflation. Set the vehicle on a proper lifting device before deflation of the air suspension system while venting its air compartments. Maintain air suspension components only after powering off by switching off the air suspension setting which is located on the left side of the luggage compartment. The rear air spring retainer should come off next while supporting the vehicle height. Then lift the bottom of the air spring from the rear axle to remove it. Pull out the air line by compressing the quick connect locking ring then disconnect its electrical connector. It is crucial to prevent the suspension from compressing before filling the air spring during installation. Install the white air line into the fitting until it reaches the end of the installation process. Install the air spring assembly into the frame seat after positioning then slide in the spring retainer clip before seating the bottom of the air spring onto the rear axle. Pontiac Aztec owners should attach the air spring solenoid valve by hooking up both the electrical connector and air line while making sure the air spring maintains its correct form during air spring refilling.

Service and repair of air springs start by verifying that all parts of the air spring piston remain unclamped. Set the air spring onto a smooth flat surface. Start the service by taking out the air spring solenoid which lets the compressed air bag expand. After expansion you should push the membrane over the piston to obtain the desired height. The correct height can be sustained through installing the air spring solenoid afterward.

Before starting air spring repair or servicing workers must verify that none of the air spring piston remains clamped. Locate the air spring on a flat floor and detach the air spring solenoid to allow the compressed air chamber to expand. Moving the membrane downward on top of the piston creates the desired height for the next step. The final step should be the installation of the air spring solenoid for height maintenance.

Touching the air spring requires checking for total pressure elimination to eliminate risks of damage to the vehicle and personnel injury. A breach of the air compressor system air line will create unpredictable high-pressure air releases which produces threats to personnel safety and equipment destruction. Installation or inflation of damaged and unfolded rear air springs must be prevented because refolding these items precedes any installation and dealers should replace found air springs with improper folds during inspections. It is essential to not add air to an air spring which descended from the rebound hanging stage into the jounce stop position. The installation of a replacement air spring should never receive suspension loading before the air springs reach their required inflation level. Check the shape of the air spring after it receives air pressure. You need to lift the vehicle on a sufficient device while switching off the air suspension button which exists on the left side of the luggage compartment before starting any air suspension deflation procedure. First elevate the vehicle for support after which you should eliminate the rear air spring retainer to remove the bottom of the spring from contacting the rear axle. The electrical connector needs removal after which a push on the red air line retaining ring will release the air line so that you can remove the air spring. Before inflation of the air spring installation must proceed without any compression of the suspension. Place the air spring assembly into its frame seat before adding the retainer clip and position the bottom of the air spring onto the rear axle. Complete insertion of the white air line into its fitting must be verified before final connection. Hook up the air spring solenoid valve by joining electrical wires with air lines but keep the air spring properly shaped with no wrinkles and refill its pressure.

Ensure that there is no pressure in the air spring before removal to prevent vehicle damage or personal injury.

Ensure that there is no pressure in the air spring before removal.

Ensure that no portion of the air spring piston is clamped.

Reinstall the air spring solenoid to maintain this height.

Place the air spring on a flat surface.
