32 00 620 Adjusting rear axle
Turning the adjusting screw on the swinging arm or on the wishbone always results in a camber and toe change!
Separate camber or toe adjustment is no longer possible!
Specific camber and toe adjustment is only possible with the aid of the following diagram!
- After an adjustment of the rear axle which alters the driving axis, check ADJUSTMENT OF ACC SENSOR
Vehicles with rear axle slip angle control only:
- Carry out adjustment of rear axle only with aid of BMW Diagnosis and Information System
Procedure, lane/camber adjustment (in design position)
Unit of measurement in diagram: [min]
| A | Toe | 1 | Actual value | |
| B | Camber | 2 | Intermediate adjustment value | |
| C | Toe/camber value adjustment by wishbone | 3 | Setpoint value in KO position | |
| D | Toe/camber value adjustment by swinging arm |
Description using the example value entered at the top of the diagram:
- Read off actual value (1) for toe/camber on wheel/axle alignment analyzer and enter in diagram
(in example: toe -16', camber -90')
- Drag parallel line to "Wishbone" line (C) through entered actual value (1)
- Point of intersection (2) on "Swinging arm" line (D) produces toe/camber intermediate adjustment value
(in example: toe -2', camber -117')
- Adjust intermediate adjustment value (2) by turning adjusting screw on wishbone
- Refer to "Adjusting on wishbone" operation described below.
- Adjust setpoint value (3) for toe/camber by turning adjusting screw on swinging arm (toe/camber value moves on line (D))
- Refer to "Adjusting on swinging arm" operation described below.
Procedure, toe/camber adjustment for ride-height-dependent measurement (unloaded)
Unit of measurement in diagram: [min]
| A | Toe | 3 | Specified setpoint value from wheel/axle analyzer system | |
| B | Camber | |||
| C1 | Toe/camber value adjustment by wishbone | |||
| D1 | Toe/camber value adjustment by swinging arm |
Description of setting using the diagram (ride-height-dependent measurement/unloaded)
- Read off nominal value (3) at wheel/axle analyzer and enter in diagram (in example: toe +17'/camber -78')
- Move lines (D) and (C) in parallel so that the point of intersection of the two lines (D1 and C1) is the entered setpoint value
- Read off actual value (1) for toe/camber on wheel/axle alignment analyzer and enter in diagram
- Further procedure as when adjusting in design position:
- Drag parallel line to "Wishbone" line (C 1) through entered actual value
- Point of intersection on "Swinging arm" line (D1) produces toe/camber intermediate adjustment value
- Adjust intermediate adjustment value by turning adjusting screw on wishbone
- Refer to "Adjusting on wishbone" operation described below.
- Adjust setpoint value (1) for toe/camber by turning adjusting screw on swinging arm (toe/camber value moves on line D1)
- Refer to "Adjusting on swinging arm" operation described below.
Adjusting on wishbone
Replace nut (1) prior to adjustment and join to 5 Nm.
Turn eccentric bolt (2) until intermediate adjustment value is obtained.
Tighten nut (1).
Tightening torque 33 32 8AZ .
Adjusting on swinging arm:
Replace nut (1) prior to adjustment and join to 5 Nm.
Turn eccentric bolt (2) to adjust setpoint value.
Tighten nut (1).
Tightening torque 33 32 2AZ .
