Pinpoint Test F: The Vehicle Binds in Turns/Resists Turning/Pulsates/Shudders in a Straight Line
Refer to Vehicle/Diagrams, Four-Wheel Drive System for schematic and connector information.

Normal Operation
When the vehicle is operating in all wheel drive (AWD) LOCKED mode, the front and rear driveshafts 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 AWD system to operate correctly, each wheel/tire assembly must have matching sizes and the front and rear axle ratios must match.

This pinpoint test is intended to diagnose the following:
^ Unmatched tire sizes
^ Unequal amounts of tire wear
^ Unequal tire inflation pressures
^ Unmatched front and rear axle ratios
