4 Symptoms of a bad suspension

No matter how modern or upgraded the Jeep is, every part has some lifespan and needs maintenance as time approaches. However, this lifespan reduces if you overload the Jeep, drive roughly, or have poor maintenance habits.

Four signs the Jeep shows to notify that your suspension is bad are:

1. Front/rear shock-absorber failure

Rattling, knocking, or popping sounds signal the failure of shock absorbers. You will hear this noise, especially driving through potholes or speed breakers. The shock absorbers fail due to oil leaking, mainly from the failed oil seal. 

However, we recommend you change your Jeep’s shock absorbers after covering every 50,000 miles.

2. Front, upper, and lower control arm failure

Ageing of suspension causes imbalanced handling that even leads to unusual tire wear. 

3. Clunking noise from the front or rear end

When you notice a clunking noise coming from the front or rear end while driving, and it gets worse on bumpy roads and rough terrains, your suspension’s anti-roll bar subframe has issues. Either the mounting bush has worn out, or the joint is displaced.

4. Worn or loose bushings

Aging causes multiple issues. The bushing gets worn or loose with time causing unnecessary movements of the anti-roll bar that causes a continuous noise. You can also hear noise when the rubber boots get worn out.

Jeep Grand Cherokee air suspension problems

The Jeep Grand Cherokee air suspension is quite different from the regular metal-spring suspension. I understand that you have paid a fortune to buy this luxurious car. Still, unfortunately, with time, its suspension will get issues, including:

1. Rear sagging of Jeep

When the suspension starts getting faulty, the Jeep cannot maintain its adequate riding height, due to which the rear side of the Jeep takes dips.

2. Failed air spring

The airbag spring is made of soft rubber components that wear off with time, leading to suspension issues.

3. Punctured airlines 

Air lines complete the circuit in a compressor. A leakage in an airline forces the compressor to work extensively. Hence, resulting in the noisy compressor.

4. ‘Nose dive’ warning message

When the front end of your Jeep Grand Cherokee dives while braking is notified as a nose dive warning.

5. ‘Immediate Air Suspension Service Required’ warning

The warning light or message on the dashboard stating that the air suspension requires immediate service or repair shows some severe problem with the suspension.

6. Noisy compressor

If the jeep compressor runs noisier than usual, your vehicle might have compressor issues. It happens when the suspension’s air lines or air dryer breaks out. 

7. Stiffness in driving

Suspension failure causes stiffness in driving, more power than usual and unbalanced driving, which might result in uneven wear and tear of tires.

8. Failed ECU

The electronic Control Unit is linked to all the vehicle parts, reading the error codes and reporting them through warning messages. Failure of ECU might also result in suspension issues.

How to troubleshoot the air suspension issues?

There are two methods to troubleshoot the air suspension system on your own:

Manual method: 

  • Inspect all the lines starting from the reservoir tank to the compressor, struts, or springs. 
  • The Reservoir tank is located under the cargo seat/rear seats and the compressor is located in front of the passenger wheel.
  • Take soap and water and spray on all the air/pressure lines. Whenever bubbling occurs, you have successfully found the source of the leak.
  • If you find any leaks replace the pipe or repair the damage with any suitable adhesive.
  • If no leaks are found, check the 40-amp fuse of the air suspension, which is located under the bonnet. If it seems black/blown out, it needs replacement unless it will seize the compressor soon.

Digital method: 

Take the OBD-II scanner and read all the DTC codes to know the faulty part. This method is easier, but usually, people who are mechanical professionals keep this scanner; otherwise, it is generally preferred to take the Jeep to a mechanic.

How to repair the Grand Cherokee air suspension system?

Unfortunately, there are no quick hacks to fix your suspension system. Either you need to replace the whole suspension system parts, which is a costly solution, and another way is to replace your air suspension system with a conventional suspension system.

I recommend you replace the whole suspension system with a traditional one. If you try replacing individual parts, they will only give you up to 10,000 miles. No other local company could match the quality of the German manufacturing facility of a jeep. 

So, you will end up devastated at the mid-side of the road having your Jeep in broken condition.

Jeep Grand Cherokee air suspension repair cost 

Replacing all the air suspension parts is expensive, costing around $3000 to $3500.

Replacing the complete air suspension with a conventional one is a relatively cheaper but reliable way of doing so. It will cost you around $1800 to $2000, including labor costs.

How to improve Jeep Grand Cherokee air suspension reliability?

Here are some tips for your Jeep’s suspension to remain healthy for longer.

  • Avoid overweighting
  • Drive responsibly
  • Use high-performance tires
  • Maintain adequate wheel-alignment
  • Inspect airline, air pressure, and shock absorbers regularly 
  • Control wheel wobble, sway, and balance of the car
  • Inspect the Jeep’s steering system regularly

Can you drive Jeep Grand Cherokee with bad air suspension?

Whether it is a leaking line issue, compressor knocking noise, or any warning message flashing up, driving your Jeep with a bad suspension is not recommended. Going with pertinent issues could cause danger to your safety and health.

You could face issues like:

  • Losing control while driving
  • Uneven driving
