Ride Height

Proper ride height is necessary for correct wheel alignment. Ensure tires are correctly inflated, cargo compartment is empty and fuel tank is full. Bounce vehicle several times to normalize ride height.
Most vehicles provide front wheel alignment specifications which allow camber and caster adjustment for a large range of ride heights. See RIDE HEIGHT SPECIFICATIONS table. Ride height measurement points are shown. See Fig 1-Fig 6 .
