Honda has announced new diagnostic tools to help diagnose and correct pulling and/or steering wheel off-center issues.
These tools/materials include:
* Centering tape T/N 07AAJ-001A300
* Steering wheel drift set level T/N 07AAJ-001A200
* Steering drift set T/N 07AAJ-001A140
* Replacement weight for steering drift set T/N 07AAJ-001A400
The holding force gauge (included in the drift set) measures the amount of pull on the vehicle. This features a bracket and weights that attach to the steering wheel on the side opposite the direction of pull (for example, if the vehicle pulls to the right, mount the holding gauge on the left side of the steering wheel). Start with the maximum amount of weight on the steering wheel and remove weights one at a time until the vehicle drives in a straight line. When recording the pull on your worksheet, write down the direction of the pull and the number of weights required to balance the pull. Note that the bracket counts as one weight. If two weights are required to correct the pull, count this as three (bracket plus the two weights).
The road crown (level) gauge measures the amount of road crown. Use the suction cup to attach the road crown gauge bracket to the face of the center gauge on the instrument cluster (directly ahead of the steering wheel). If necessary, bend the gauge bracket until the gauge reading is vertical. Once you attach and align the road crown gauge, calibrate the gauge to zero. Park the vehicle on a level surface, such as an alignment rack, and calibrate the gauge by moving the gauge until the ball is at the zero mark. If you do not have an alignment rack available, park the vehicle on a reasonably flat and level surface and note the gauge reading. Then, turn the vehicle 180 degrees and park on the same spot and note the gauge reading. Then move the gauge half of the difference. For example, if your first reading is +3, and after moving the vehicle 180 degrees with the tires on the same locations, if the reading is –1, then the difference is 4 degrees. In this case, you would position the gauge to read +1.
NOTE: You must calibrate the gauge with the same weight in the vehicle that you will use for the test drive. If you plan to have an assistant help you during the test drive, calibrate the gauge with both of you sitting in the vehicle.
The steering wheel offset gauge is a sticker that attaches to the steering wheel and the steering column cover. Place the sticker on the steering wheel when the steering wheel is positioned straight. When you test drive the vehicle, you can read how many millimeters the steering wheel is off-center.
For procedures to diagnose and correct for road crown, tire pull, suspension/steering issues, etc., refer to the instructions supplied with the service-test tools.
