Why Your 4WD Isn’t Working

When the winter hits and it’s time to change over from 2WD into 4WD, that means a few things. In some cases it can mean lower MPG’s and more stability — but for some it can induce the ‘why isn’t this working’ question when your car still won’t move. In some cases, diagnosing a 4WD issue is sometimes a computer issue — but in others, i can be a simple inspection of the car.

Shifter

Some trucks and more off-road tuned cars include separate shifters to engage 4WD and get you moving when you need it. Of course, over time and due to excessive wear/tear, these items can begin to get worn out, snap, and not work. When this happens, that shifter might feel as if it’s moving a bit more freely than it should, seemingly not locking into another gear. If this is the case, there might be an issue with the shifter in your car/truck

Connections Underneath

When you engage 4WD, your driveline in the rear essentially connects in some way to the front, which sends power to all 4 axles, and then the wheels. When there’s a connection interference, that connection may not be made and may require a diagnosis. Something as small as a rock, stick/ ice or other debris can sometimes cause the issue and pose a threat for your gearing as you try to get it working. If this is the case, don’t force anything in just yet. Inspect, and then bring it in for a diagnosis.
