Grand Cherokee Jeep Rear Right Air Suspension Bag New Unit Replacement

Product Overview

High Load-Bearing, OE Specification Air Spring (Air Bag) For Jeep Grand Cherokee Rear Right Position (Air Spring Only, Without Shock Absorber Core)

Specifications

Vehicle Application	Jeep Grand Cherokee (WK2, 2011-2021)
Installation Position	Rear Right (Vehicle Right Side, Passenger Side Rear on LHD Vehicles)
Component Type	Air Spring (Air Bag Only, Must Be Used with Original or New Shock Absorber Core)

Product Description

This air spring is designed for the rear air suspension system of the Jeep Grand Cherokee WK2 chassis, specifically for the rear right (passenger side rear) position. This product is an air spring only and does not include a shock absorber core. It is suitable for repair scenarios where the original rear shock absorber core is still fully functional but the air spring has aged, cracked, or failed.

As Jeep's flagship SUV, the Grand Cherokee WK2 balances on-road comfort with off-road capability in its rear air suspension design. The rear right air spring is located on the passenger side rear and must accommodate vehicle height adjustment needs under different load conditions, working in coordination with the Quadra-Lift air suspension system.

Constructed with high-strength rubber composite material and aluminum alloy upper/lower mounts, this air spring works in coordination with the rear shock absorber core, stabilizer bar and height sensor to form the rear portion of the Jeep Quadra-Lift air suspension system. This product features automatic self-leveling functionality, offering multiple height adjustments including park height, normal ride height, and off-road height.

The Jeep Grand Cherokee WK2 was produced between 2011 and 2021, and rear air spring failure is a common repair item on this model, especially as vehicles accumulate higher mileage or age. This product is manufactured to original equipment structural dimensions, with air bag diameter, upper and lower mounting hole positions, air line connector specifications, and seal ring dimensions all consistent with original factory specifications, allowing direct replacement of the old air spring without any modifications. The left and right sides have different part numbers. Please confirm the required position before purchasing.

Key Features

Independent Air Spring (No Shock Absorber Core): Designed for scenarios where the shock absorber core is intact and only the air spring has failed, reducing repair costs
Position Specific: Designed specifically for the rear right (passenger side rear) position; left and right air springs have different part numbers and are not interchangeable
Quadra-Lift Compatible: Supports multi-level vehicle height adjustment, working with the Jeep air suspension system
High Load-Bearing Design: Multi-layer reinforced rubber construction, adapted to the Grand Cherokee's heavy load and off-road conditions
Reliable Sealing: Original specification seal rings and crimping process reduce slow leak risk
Factory Tested: Each unit undergoes high-pressure air tightness testing and load cycle verification

Important Note

⚠️ This product is suitable for the Jeep Grand Cherokee WK2 chassis (2011-2021), including 3.0L, 3.6L, 5.7L, 6.4L and other powertrain versions. The rear left and rear right air springs have different part numbers. Please confirm the required position before purchasing. Differences may exist between different model years and configurations. Please verify the original OE part number or VIN code before purchasing. This product is an air spring only and does not include a shock absorber core; installation requires use with the original or a new shock absorber core. It is recommended to replace both rear left and rear right air springs as a pair for balanced suspension performance.

Frequently Asked Questions

Q1: How can I tell whether the Grand Cherokee WK2 rear right air spring is already damaged?

Common signs of damage include: the right rear body side noticeably sinking after the vehicle sits overnight (lower than the left side), the air compressor running frequently after starting (every few minutes), a "hissing" noise from the right rear wheel when going over bumps, and an "Air Suspension Fault" or "Service Air Suspension System" warning on the dashboard. On the Grand Cherokee, air spring leaks commonly occur at the bottom folds of the air bag. A simple self-check method: after stopping the vehicle and turning off the engine, spray soapy water on the air spring surface and observe if bubbles appear.

Q2: Is it acceptable to replace only the air spring and keep the old shock absorber core?

Yes, they can be used together, but two conditions must be met: First, the original shock absorber core must be in good condition - no oil leakage, no damping degradation, no abnormal noise. Second, the shock absorber core should generally have no more than 100,000 km of service. The Grand Cherokee WK2 has a wide range of model years, so high-mileage vehicles should have the shock absorber core inspected at the same time. The combination of new and old components will not affect the air spring's operation, but degraded damping from the aged shock absorber core will affect the Grand Cherokee's driving stability and off-road performance.

Q3: After replacing the air spring, the instrument panel shows an "Air Suspension Fault" warning, but the vehicle drives normally. What is the cause?

This situation is usually not a problem with the air spring itself, but rather the air suspension system has not been reset after installation. After replacing rear air springs on a Jeep Grand Cherokee WK2, a diagnostic tool (such as JSCAN, WiTECH, or a compatible device) is required to perform "height calibration" and "system learning" on the Quadra-Lift system. Even if the air spring is physically installed correctly, the system may still report an error due to height sensor zero-point offset. It is recommended to connect a diagnostic tool after installation, clear the fault codes, and perform rear axle height initialization.

Q4: Is the Grand Cherokee WK2 rear right air spring suitable for different powertrain versions (3.0L/3.6L/5.7L/6.4L)?

Yes, it is suitable. The rear air spring structure is the same for different powertrain versions, with identical mounting dimensions. The load capacity of the air spring covers all powertrain versions. The 5.7L and 6.4L V8 versions are slightly heavier, but the air spring design accounts for this and can be used without issue. When purchasing, you only need to confirm that your vehicle is the WK2 chassis.

Q5: What accessories are recommended to replace at the same time as the rear right air spring?

It is recommended to replace the following accessories simultaneously: the air spring upper cap seal ring (may deform after removal), the air line connector clamp (original clamp loses clamping force after removal), and the buffer pad between the air spring and shock absorber core (may harden after long-term compression). In addition, check the right rear height sensor link for integrity, check whether the compressor dryer is saturated, and check whether the air distribution valve is functioning properly. The Grand Cherokee WK2 compressor dryer typically has a service life of 5-7 years, so it is recommended to inspect it as well.

Q6: After replacing the air spring, the rear axle feels stiffer or bumpier than before. Is this normal?

Yes, this is normal. Old air springs may have hardened rubber and reduced elasticity even before leaking. New air springs restore factory elasticity, which may initially feel firmer as the filtering effect improves. The Grand Cherokee's factory rear axle tuning is biased toward comfort while also accommodating off-road use, so the "stiffer" feel of the new air spring will not be too pronounced. Typically, after driving 300-500 km, the air spring will gradually adapt to the vehicle load and the ride feel will become normal. If the rear axle still feels noticeably bumpy after more than 800 km, check whether the installation is correct or whether the correct model was matched.

Q7: There is a "creaking" or "squeaking" noise from the right rear wheel area while driving after air spring replacement. What is the cause?

This type of noise requires careful diagnosis on the Grand Cherokee. Common causes include: 1) The bolts connecting the air spring upper cap to the body are not tightened to the specified torque; 2) The buffer pad between the air spring and shock absorber core is installed incorrectly or missing; 3) The right rear stabilizer bar link ball joint is aged, producing noise when working with the new air spring; 4) The height sensor link was bent or stuck during installation; 5) The parking brake cable is pinched between the air spring and the body during installation. As an off-road vehicle, the Grand Cherokee has a longer rear axle suspension travel, so extra attention should be paid to accessory positioning during installation. It is recommended to first check bolt torque and the buffer pad, then inspect other accessories if the noise persists.

Q8: Is a wheel alignment (chassis angle calibration) necessary after replacing the Grand Cherokee WK2 rear right air spring?

Rear axle alignment is recommended. The WK2 chassis Grand Cherokee rear suspension is a multi-link design. Replacing the air spring involves changes in rear axle ride height, and the installation process may involve disconnecting the lower control arm from the subframe, which can affect rear wheel toe and camber after installation. Common consequences of skipping wheel alignment include: uneven rear tire wear and unstable rear end at high speeds. It is recommended to drive 30-50 km after replacement to allow the suspension to settle naturally before performing a rear wheel alignment.

Q9: Is the WK2 rear right air spring suitable for the later generation WL Grand Cherokee?

No, it is not suitable. The WL is the next-generation Grand Cherokee launched in 2021, with a completely different chassis structure, suspension geometry, and air spring mounting dimensions. Parts are not interchangeable with the WK2. Before purchasing, please confirm that your vehicle is the WK2 chassis (2011-2021 model years), which can be verified via VIN code or vehicle registration information.

Q10: Why does the air compressor run frequently after replacing the rear right air spring?

If the air compressor still runs frequently after installing a new air spring, possible causes include: 1) Height calibration has not been performed, and the system is still operating based on the old air spring height parameters; 2) The compressor dryer is saturated, affecting inflation efficiency (a common issue on the Grand Cherokee); 3) The compressor itself is aged, slowing down inflation speed; 4) The right air spring still has a leak after installation (air line connector or seal ring issue); 5) The air distribution valve has an internal leak. It is recommended to first perform height calibration using a diagnostic tool. If the problem persists, check the compressor dryer and distribution valve condition.

Q11: Should the WK2 rear air springs be replaced as a pair?

Replacing as a pair is recommended. Although it is possible to replace only the damaged side, both air springs have been in service for the same number of years and have similar rubber aging. Failure on one side often indicates the other side is also near the end of its service life. As an off-road SUV, the Grand Cherokee's left and right rear air springs experience similar loading conditions. Replacing as a pair avoids the other side failing in the short term and ensures balanced left-right suspension support. If you plan to keep the vehicle for more than 2 years, replacing as a pair is a more economical choice.
