Preliminary Checks
NOTE:
On vehicles with electronic chassis controls, ensure systems are functional before adjusting riding height or wheel alignment.
CAUTION:
Do not re-use any fasteners that are worn or deformed in normal use. Some fasteners are designed to be used only once, and are unreliable and may fail if used a second time. This includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow the recommendations and replace fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.
Before aligning the vehicle, ensure the following are checked or performed.
- Test equipment must be properly adjusted and attached to vehicle (refer to equipment manufacturer's instructions)
- Equal tread depth for both tires on each axle, with difference between two not more than 0.079" (2 mm). Tires inflated to correct pressure.
- Sliding plates and turntables not positioned against any stop when checking wheel alignment.
- Vehicle at correct curb weight. Curb weight is defined as: the weight of the vehicle ready for the road (fuel tank completely full, spare wheel, vehicle tool kit and vehicle jack all in specified positions).
- Vehicle accurately positioned, suspension bounced and rocked several times and allowed to settle.
- Suspension, steering and steering linkage in proper condition with no damage or excessive play.
