2005 Jeep Grand Cherokee Front Differential Noise (Cause & Fix)

If your 2005 Jeep Grand Cherokee is experiencing front differential noise, then today, you’re going to find some of the possible causes and how to fix it.

A differential component is an essential component of your vehicle that is responsible for the transfer of power from the engine to the wheels.

Therefore, if it is making unusual sounds you need to investigate it and get it fixed.

What is a Differential in Cars?

A differential is a system of gears in vehicles that allows different drive wheels  ( the wheels to which the power is delivered from the engine) on the same axle to rotate at different speeds especially when the car is turning.

The differential is also the component that makes it possible for the rotating driveshaft to change direction.

Generally, differentials are low maintenance, sealed components that are expected last the lifetime of the vehicle. But there are recommended service intervals to check and/or replace the oil.

A failing differential can cause vibration, binding during turns, and/or sounds ranging from clunking to howling.

Causes of 2005 Jeep Grand Cherokee Front Differential Noise

Front differential noise can be caused by several factors and here, we will discuss the different reasons for your Jeep’s front differential noise.

1). Lack of Maintenance

As earlier stated, the differential components are meant to last the life of the vehicle but they require maintenance to keep them lasting.

Otherwise, poor or no maintenance can cause the front differential wheel drive to deteriorate and properly eventually cease to function correctly thereby causing differential noise.

How to Fix It

You will need to maintain your front differential wheel drive by replacing the oil and doing the recommended maintenance to ensure a favorable long-term impact and longer vehicle lifespan.

2). Rings and Pinions that have Been Worn Out

If you are hearing a humming noise in your Jeep, then it could be caused by the ring gear distortion. Worn-out pinions and rings can cause noise to be generated.

How to Fix Worn-Out Rings and Pinions

To solve the humming or whining noise coming from the differential components, then you will need to replace the worn-out rings and pinions. You need to get the right size and model.

To do this, you will need to check the owner’s manual for the right model and the instructions to follow.

3). Vehicle Carrier Bearing Distortion

When you are making a U-turn, you may hear a rumbling noise which is a type of front differential noise that can cause the vehicle to harden. This mostly happens when the carrier bearing is deformed.

If this issue is not addressed immediately, the noise levels get high and can cause severe damage to other vehicle parts especially those components that are near the carrier bearing.

4). Distortion in the Universal Joint Mechanism

A universal joint allows the power to flow straight and at the proper angle. It also allows more flexibility and optimal power transmission from the engine to the wheels.

If for some reason, the universal joint fails, the power flow from the engine can be restricted at an angle and therefore cause a grinding noise.

The worn-out universal joint can also cause vibration in the front differential wheels which in turn can also affect other vehicle components negatively. Thereby increasing costs of repairs.

How to Fix the Issue 

The best way to fix this issue is to replace the universal joint with a new one. If you can’t do it yourself, employ the services of a qualified auto mechanic.

5). Loose or Worn Out Front Differential wheel Drive

Wear and tear can cause noise to occur in the front differential wheel drive and even cause them to get loose. This can in turn interfere with the smooth running of the wheels and cause front differential noise.

How to Fix it

Inspect the front and back wheels for any damage after you notice noise coming from the differential wheels. You will need to let a mechanic help you out.

6). Broken Front Axle

If you are hearing banging sounds, it’s mostly caused by a worn-out front axle. Any deformation can cause the noise to occur.

How to Fix Broken Front Axle

To fix the issue, you will need to replace the front axle. To replace it, you need to get a front axle that is compatible with your car model which is a 2005 Jeep Grand Cherokee vehicle.

7. Inadequate Gear Installation

Clicking sounds can be a result of improper installation of the gears particularly the side gears. Other things like poor gear installation and broken or damaged equipment can cause clicking sounds.

Also, loose car gears can cause whirring noise that could prove difficult to diagnose. You may need the services of a qualified mechanic to find out the issue and help you.

Final Thoughts

Sounds coming from your Jeep Grand Cherokee front differential wheel is a sign that something is wrong with the vehicle and you need to attend to it immediately.

If you leave these unfamiliar sounds to continue, the damage may be bigger and cost more money to repair.

Therefore, the tips recommended above will help you. But if you are unable to do it yourself, then consult a qualified mechanic to diagnose and fix the front differential noise issue for you.
