OE 68029912AE is an exclusive rear air spring sealing repair kit for Jeep Grand Cherokee WK2 chassis, covering multiple generations of original iterative universal OE numbers, and is the most widely adapted and stable replacement accessory for WK2 rear air spring maintenance in the market.

After long-term use, the original rear air spring of WK2 is affected by vehicle heavy load, bumpy roads and seasonal temperature differences, prone to aging & hardened sealing rings, cracked dust boots and failed gaskets, resulting in typical common problems such as slow rear end sagging, static pressure relief, uneven rear wheel height, bumpy abnormal noise and occasional air suspension warning lights. All these faults are caused by sealing part wear and can be accurately repaired by this kit without replacing the complete rear air spring assembly.

This kit is only effective for minor sealing faults of rear air spring: slow air leakage, static pressure relief, damaged dust boots and aging rubber rings. It is not applicable for severely damaged air spring body tearing, severe oil leakage of shock core, damping failure and shell deformation, which require direct replacement of rear air spring assembly.

All sealing accessories adopt customized formula for American off-road vehicles, featuring low temperature resistance, oil corrosion resistance and tensile fatigue resistance, adapting to complex driving environments such as severe cold, high temperature, mountain off-road and daily full load. It supports non-destructive in-situ replacement without chassis modification. After assembly, air tightness test, vehicle height reset and fault code clearing can completely restore the working performance and driving comfort of the original rear air spring.

> Important Notice: This exclusive repair kit is specially designed for WK2 rear air spring, universal for rear left/right, front/rear non-universal; only fits factory air spring models, mechanical spring models are not applicable.

Q3: When to use repair kit and when to replace rear air spring assembly?

A: Repair kit applies for: aged sealing rings, cracked dust boots, failed gaskets, rear air spring slow air leakage, rear end sagging and minor abnormal noise, with intact air spring body and normal damping; Complete assembly replacement is required for: torn rear air spring, severe core oil leakage, damping failure and deformed shell, which cannot be repaired by the kit.

Q4: Is computer programming required after installation?

A: No complex programming required. Air tightness leakage test, vehicle height calibration and fault code clearing must be performed after repair to avoid uneven rear end height, air suspension alarm and driving deviation.

Q5: Does the repair kit include rear air spring, shock core, sensors and wiring harnesses?

A: No. This is a pure vulnerable sealing part repair set, only including rubber rings, gaskets, dust boots and fastening clamps. Original intact rear air spring body, core and sensors can be reused directly.
