RAM 1500 Air Suspension Problems: Causes and Solutions

The RAM 1500 is a popular full-size pickup truck that is known for its powerful engine, great towing capability, and comfortable ride. One of the features that make the RAM 1500 stand out is its air suspension system, which provides a smooth ride and better handling.

However, some owners have reported problems with their RAM 1500 air suspension system. In this article, we will discuss the most common RAM 1500 air suspension problems, their causes, symptoms, and solutions.

The RAM 1500 air suspension system is designed to improve the truck’s ride quality, handling, and overall performance. It is a complex system comprising various components, such as air springs, compressors, air lines, and electronic control modules (ECM).

While the air suspension system is a great feature that provides a comfortable ride, it can also cause problems if not properly maintained.

What is an Air Suspension System?

An air suspension system is a type of suspension system that uses compressed air to support the vehicle’s weight and absorb shocks from the road. It consists of air springs, which are also known as airbags, and a compressor that pumps air into the springs.

The system is controlled by an electronic control module (ECM) that monitors the ride height and adjusts the air pressure in the springs to maintain a smooth ride.

Common RAM 1500 Air Suspension Problems

The RAM 1500 air suspension system is generally reliable, but it can develop problems over time. Here are some of the most common problems that RAM 1500 owners have reported:

Compressor Failure

The compressor is the heart of the air suspension system. It is responsible for pumping air into the air springs to maintain the desired ride height.

If the compressor fails, the air springs will not inflate, and the truck will sag or ride low. Compressor failure is often caused by a clogged air filter, a faulty relay, or a blown fuse.

Leaking Air Springs

Air springs can develop leaks over time due to wear and tear or punctures from road debris. When an air spring leaks, it loses air pressure and cannot support the weight of the truck.

This can cause the truck to sag or ride low. Leaking air springs should be replaced promptly to avoid further damage to the suspension system.

Faulty Air Lines and Fittings

The air lines and fittings that connect the air springs to the compressor can develop leaks or become loose over time.

When this happens, the air pressure in the system drops, and the truck may sag or ride low.

Faulty air lines and fittings should be replaced or repaired promptly to prevent further damage to the suspension system.

Electronic Control Module (ECM) Failure

The ECM is the brain of the air suspension system. It monitors the ride height and adjusts the air pressure in the springs to maintain a smooth ride.

If the ECM fails, the air suspension system will not work properly. This can cause the truck to sag or ride low. ECM failure is often caused by electrical issues or software malfunctions.

Symptoms of Air Suspension Problems in RAM 1500

If your RAM 1500 air suspension system is experiencing problems, you may notice the following symptoms:

• Sagging or riding low
• Rough ride
• Abnormal noises coming from the suspension
• Warning light on the dashboard
• Difficulty maintaining the desired ride height
• Uneven tire wear

If you notice any of these symptoms, it is important to have your air suspension system inspected by a qualified mechanic.

How to Diagnose RAM 1500 Air Suspension Problems

If you suspect that your RAM 1500 air suspension system is experiencing problems, you can perform the following checks to diagnose the issue:

• Check the air compressor for signs of wear or damage
• Inspect the air springs for leaks or damage
• Check the air lines and fittings for leaks or damage
• Use a scan tool to check for fault codes in the ECM

If you cannot diagnose the issue on your own, it is recommended to take your truck to a qualified mechanic for a proper diagnosis.

Solutions to RAM 1500 Air Suspension Problems

The solutions to RAM 1500 air suspension problems will depend on the specific issue that is causing the problem. Here are some common solutions:

Repair or Replace the Compressor

If the compressor is faulty, it may need to be repaired or replaced. In some cases, a clogged air filter, a faulty relay, or a blown fuse may be the cause of the problem, which can be fixed easily.

Replace Leaking Air Springs

If the air springs are leaking, they will need to be replaced. It is important to replace both air springs at the same time to maintain balance and stability.

Repair or Replace Faulty Air Lines and Fittings

If the air lines or fittings are faulty, they may need to be repaired or replaced. It is important to use OEM parts to ensure proper fit and function.

Replace Electronic Control Module (ECM)

If the ECM is faulty, it will need to be replaced. The replacement ECM must be programmed with the correct software to ensure proper operation.

Preventive Measures to Avoid Air Suspension Problems

To avoid air suspension problems in your RAM 1500, it is important to follow these preventive measures:

• Regularly inspect the air suspension system for signs of wear or damage
• Keep the air filter clean and replace it as necessary
• Avoid overloading the truck beyond its capacity
• Drive carefully and avoid rough roads and terrain

FAQs

Can I drive my RAM 1500 if the air suspension system is not working?

It is not recommended to drive your RAM 1500 if the air suspension system is not working properly. This can cause further damage to the suspension system and affect the handling and stability of the truck.

How much does it cost to repair or replace the air suspension system in a RAM 1500?

The cost of repairing or replacing the air suspension system in a RAM 1500 can vary depending on the specific issue and labor cost in your area. It is important to get a proper diagnosis from a qualified mechanic to determine the exact cost.

Can I replace the air springs in my RAM 1500 myself?

While it is possible to replace the air springs in your RAM 1500 yourself, it is recommended to have a qualified mechanic perform the replacement to ensure proper installation and function.

How often should I inspect my RAM 1500 air suspension system?

It is recommended to inspect your RAM 1500 air suspension system at least once a year or more frequently if you frequently drive in rough terrain or carry heavy loads.

What should I do if I hear abnormal noises from my RAM 1500 air suspension system?

If you hear abnormal noises from your RAM 1500 air suspension system, it is important to have it inspected by a qualified mechanic as soon as possible to avoid further damage and potential safety hazards.

Conclusion

The RAM 1500 air suspension system is a great feature that provides a comfortable ride and better handling. However, it can develop problems over time, such as compressor failure, leaking air springs, faulty air lines and fittings, and ECM failure.

If you notice any symptoms of air suspension problems, it is important to have your truck inspected by a qualified mechanic. To avoid air suspension problems, it is important to follow the preventive measures mentioned in this article.
