Owners of 2014 Jeep Grand Cherokee models may notice uneven vehicle stance or illuminated warning lights indicating air suspension issues. These systems require specialized attention compared to traditional coil setups, particularly when addressing component failures or considering conversion alternatives.
What suspension gives the best ride?
Why Do Jeep Grand Cherokee Air Suspensions Fail Frequently?
Common failure points include cracked air springs (due to ozone exposure), compressor burnout from moisture ingress, and faulty height sensors. The 2014 model’s aluminum compressor housing is prone to corrosion. Driving on deflated air springs accelerates compressor failure. Climate extremes and frequent load adjustments exacerbate wear.
Environmental factors play a significant role in air suspension degradation. Vehicles in coastal regions face accelerated corrosion due to salt air, while extreme temperature fluctuations in desert climates cause rubber components to dry-rot. The system’s constant pressure adjustments during highway driving create cumulative stress on air springs. Jeep’s original equipment manufacturer (OEM) compressor contains a cellulose desiccant that loses effectiveness after 2-3 years, allowing moisture to damage internal valves.
| Failure Cause | Prevention Method | Average Repair Cost |
|---|---|---|
| Air spring cracks | UV-protectant sprays | $400-$600 per corner |
| Compressor corrosion | Annual drain port cleaning | $800-$1,200 |
| Sensor malfunctions | Monthly connector inspections | $150-$300 |
What Maintenance Extends Air Suspension Lifespan?
Monthly inspections for air leaks, annual compressor filter replacements, and biannual system recalibrations are critical. Avoid overloading beyond Jeep’s 7,200-lb towing capacity. Use winter mode in cold climates to prevent moisture freeze-ups. Park on level surfaces to reduce strain on height sensors.
How much does good air suspension cost?
Proactive maintenance should include using a tire pressure gauge to monitor suspension firmness – variations exceeding 3 PSI between corners indicate potential leaks. During oil changes, technicians should inspect the compressor’s air dryer for moisture saturation. Owners in snowy regions should apply dielectric grease to electrical connectors every fall to prevent corrosion. The system benefits from monthly exercise cycles: with engine running, cycle through all ride heights using the dashboard controls to keep valves operational.
“The 2014 Grand Cherokee’s air suspension needs proactive care. I recommend annual diagnostics using factory-grade scanners. For owners in salt-belt states, corrosion-resistant aftermarket compressors are worth the investment. Always replace air springs in pairs to maintain balance.” – Mark Tutton, Senior Technician at Duralast Suspension Specialists
FAQ
- Q: Can I drive with a failed air suspension?
- A: Limited to 50 mph for short distances. Prolonged driving damages the compressor and shocks.
- Q: Do I need an alignment after replacement?
- A: Yes. Ride height changes necessitate wheel alignment to prevent uneven tire wear.
- Q: Are rebuilt compressors reliable?
- A: Only if they include upgraded desiccant bags and corrosion-resistant seals. Warranties under 1 year are risky.
Replacing the 2014 Jeep Grand Cherokee’s air suspension requires balancing cost, functionality, and technical skill. Whether opting for OEM parts, aftermarket upgrades, or coil conversions, prioritize components that match your driving needs. Regular maintenance remains key to maximizing system longevity.
