Normal Operation
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
When the vehicle is operating in 4H, all 4 wheels rotate at the same speed. The amount of traction the vehicle can achieve is dependent on the amount of traction each tire can establish with the road surface. In order for the four wheel drive (4WD) system to function correctly, each tire must be in good condition and the front and rear axle ratios must match.
Possible Causes
- 4H indicator
- 4WD control module (PCM)
- Transfer case and related components
- Wheel/tire assemblies
