4WD Problems

Four wheel drive problems typically appear in two forms: not working, or won't disengage.

Unfortunately the 'not working' problem usually happens at an inconvenient time when you need the extra traction 4x4 provides.

The 'won't disengage' problem usual gets noticed when fuel mileage decreases significantly or excessive tire wear is noticed. Both could be prevented with periodic 4x4 vehicle inspection and regular 4WD maintenance.

Common 4WD problem symptoms:

  • decreased traction in snow or mud.
  • rattling noise when 4WD engaged.
  • "Service 4WD" indicator light is on.
  • can't disengage 4WD (4WD light on).
  • excessive front tire wear (4WD won't disengage)
  • excessive fuel consumption (4WD won't disengage)
  • lack of power (4WD won't disengage)

Simple DIY 4-Wheel Drive Check

The first thing that everyone should check before leaving on a trip that may involve snow or mud is to check that your 4WD is working.

Just because you feel or hear the 4WD transfer case engage and the light says 4WD this does not mean that the front drive hubs are engaged. Without checking you will not know your 4WD is working until you need it and have no power to the front wheels.

Here is how to check your 4WD:

  1. With vehicle on any concrete or asphalt surface. It is safer and easier to do this in a parking lot.
  2. With vehicle stopped and in neutral or park, actuate the 4WD. You should feel or hear a "clunk" as the 4WD transfer case engages.
  3. Move the vehicle straight forward about 10 feet to allow the front hubs to engage and lock.
  4. Turn your wheels all the way to one side and drive forward. You should feel the vehicle bind or resist rolling forward smoothly. If you can not feel the vehicle resisting during the turn then your 4WD is probably not working.

If you are unsure you can visit our shop and we will be happy to show you how to check the operation of your 4WD.

Common 4WD Problems

Problem: 4WD vehicle shudder, vibrate, and difficult to turn.
Cause: 4WD can not be operated on dry paved roads when in locked mode. The front and rear wheels turn at different speeds when turning and the axles "fight" each other causing drive-line shuddering, vibration, and resistance to turning.
Repair: Make sure the 4WD has not been switched on in error. Check that the 4WD is not stuck in 4WD mode even if the 4WD light is not on. Sometimes the 4WD warning light is not working and the driver does not realize the vehicle is in 4WD.

Cause: Intermittent no drive condition with random 4WD engagement usually indicates a growing problem with the transfer case shift motor encoder ring. This is often a very difficult problem to diagnose.
Repair: Diagnose and transfer case shift motor replacement. If the transfer case shift motor has failed completely the vehicle may need to be towed to repair shop for diagnosis and repair. To get vehicle to move you can try cycling the ignition key on and off a few times may get transfer case to engage. The 4WD switch light will indicate 2WD or Auto when drive engaged.
