1. Transfer Case: If the transfer case is not properly engaging the front wheels, the vehicle will pull to the front. This could be due to a mechanical issue with the transfer case or a problem with the electrical controls that engage it.
2. Driveline Components: Inspect the driveshaft, CV axles, and other driveline components for damage or wear. If any of these components are damaged or worn, they could cause the vehicle to pull to the side.
3. Differential: If the differential is not functioning properly, it could cause the vehicle to pull to one side. This could be due to a mechanical issue with the differential or a problem with the electrical controls that engage it.
4. Tire Pressure: Check the tire pressure on all four tires. If the tire pressure is too low, it can cause the vehicle to pull to one side.
5. Wheel Alignment: If the wheel alignment is out of specification, it can cause the vehicle to pull to one side.
All-Wheel Drive Not Working:
1. Transfer Case: If the transfer case is not properly engaging the front wheels, the all-wheel drive will not work. This could be due to a mechanical issue with the transfer case or a problem with the electrical controls that engage it.
2. Driveline Components: Inspect the driveshaft, CV axles, and other driveline components for damage or wear. If any of these components are damaged or worn, they could prevent the all-wheel drive from working properly.
3. Differential: If the differential is not functioning properly, it could prevent the all-wheel drive from working properly. This could be due to a mechanical issue with the differential or a problem with the electrical controls that engage it.
4. Electrical Connections: Check the electrical connections associated with the all-wheel drive system. If any of these connections are loose or corroded, it could prevent the all-wheel drive from working properly.
5. ECM/TCM: The engine control module (ECM) or transmission control module (TCM) may be responsible for controlling the all-wheel drive system. If there is a problem with the ECM/TCM, it could prevent the all-wheel drive from working properly.
