1	Carry out wheel alignment, compare the result with the test values	If substantial deviations in the total toe are found, the cause may be one of the following: Too great a difference in vehicle level between right and left-hand sides of vehicle. Deformation of the tie rod (1). Deformation of rear axle carrier, e.g. through accident damage. Deformation of the body, e.g. due to accident damage. Check for impermissible deformation on body.
