68191857AA | Genuine Mopar® Front Axle Differential 2011-2026

1. Allows Wheel Speed Difference

• When turning, the inside wheel travels a shorter distance than the outside wheel

• The differential allows each wheel to spin at the proper speed without skidding or dragging

2. Distributes Engine Power

• Transfers engine torque to the front wheels

• Balances power between left and right wheels for traction and stability

3. Works With 4WD/AWD Systems

• In 4WD vehicles, the front differential works with the transfer case and rear differential

• Ensures proper torque distribution in off-road or slippery conditions

4. Protects the Drivetrain

• Prevents stress and damage to axles, tires, and driveshafts caused by forcing wheels to spin at the same speed

1. Unusual Noises

• Whining, humming, or howling while driving, especially when turning

• Clunking or banging when shifting from drive to reverse

• Noise often increases with vehicle speed

2. Vibration or Shuddering

• Excessive vibration through the steering wheel or front end

• May feel like the vehicle is “shaking” when accelerating or turning

3. Difficulty Steering

• Front wheels may feel stiff or resistant to turning

• Especially noticeable in 4WD or AWD vehicles

4. Leaking Gear Oil

• Oil around the front differential housing, axle seals, or pinion seal

• Low differential fluid can damage gears and bearings

5. Uneven Tire Wear

• Tires may wear faster or unevenly if the differential isn’t properly distributing torque

6. 4WD or AWD Problems

• In 4WD/AWD vehicles:

  • Front wheels may not engage properly

  • Vehicle may pop out of 4WD

  • AWD warning lights may illuminate

7. Burning Smell

• Overheated differential due to low or contaminated fluid

• May smell like burnt oil
