Vehicles using AWD engine list:

Engine AWD

Symptoms:
- Unusual noises from the drivetrain, especially when accelerating or turning
- Vibrations felt through the floor or steering wheel
- Warning lights on the dashboard related to traction or AWD system
- Difficulty in maintaining traction on slippery surfaces
- Reduced fuel efficiency

Diagnosis:
- Inspect the AWD system components including the transfer case, differentials, and driveshafts for wear or damage
- Check for leaks of lubricants from the transfer case or differentials
- Scan the vehicle’s ECU for fault codes related to the AWD system or traction control
- Test the operation of the AWD system by observing engagement and disengagement during driving
- Examine wheel bearings and CV joints for wear that may affect AWD performance

Fixes:
- Replace worn or damaged driveshafts, CV joints, or wheel bearings to eliminate noises and vibrations
- Repair or replace seals and gaskets to stop lubricant leaks in the transfer case or differentials
- Service the transfer case and differentials by changing fluids according to manufacturer specifications
- Reset or update the ECU software if AWD-related fault codes persist after repairs
- Replace faulty sensors or actuators involved in AWD system control

Prevention:
- Regularly service the AWD system components, including fluid changes at recommended intervals
- Avoid aggressive driving that puts excessive strain on the drivetrain
- Inspect and maintain tires to ensure even wear and proper traction, which supports AWD function
- Address any unusual noises or warning lights promptly to prevent further damage
- Keep the vehicle’s software updated to ensure optimal AWD system performance
