Read specified value for total rear axle toe from the specified value table and compare with the result of the wheel alignment

Toe at vehicle level

*BE40.20-P-1001-10J

Permitted difference between right and left side of vehicle for rear-axle toe

*BE40.20-P-1002-10J

 If substantial deviations in the total toe are found, the cause may be one of the following:

 Too large a difference in vehicle level between the left and right sides of the vehicle,

 Deformation of tie rods e.g. through damage due to an accident,

 Deformation of rear axle carrier or of chassis parts, e.g. through damage due to an accident,

 Deformation of the body, e.g. due to accident damage.

 Check for impermissible deformation on the body. Refer to: 
