Pinpoint Test H: The Vehicle Binds In Turns/Resists Turning/Pulsates/Shudders In a Straight Line

Normal Operation

When the vehicle is operating in A4WD, (4H/4L), all four wheels receive the same amount of torque and rotate at the same speed. The amount of traction the vehicle can achieve depends on the amount of traction each tire can establish with the road surface. In order for the 4WD system to function correctly, each tire must be in good condition and the front and rear axle ratios must match.

Possible Causes

- unmatched tire sizes.
- unequal amounts of tire wear.
- unequal tire inflation pressures.
- unmatched front and rear axle ratios.

Note: 4x4 High/Low (4H/4L) is intended for driving on hard/dry surfaces.
