Vehicle Alignment

Front:

Rear:

Except 4Matic Models

Vehicle Level

Front Axle 6.9° ±1.5°
Maximum deviation between left & right:
When checking 0.75°
When calibrating w/Star Diagnosis 0.5°

Rear Axle -0.9° ±1.0°
Maximum deviation between left & right:
When checking 0.5°
When calibrating w/Star Diagnosis 0.3°

NOTE: To measure vehicle level use (86) Electronic inclination measuring instrument (CM 9606)

Front Toe-in 0°32 '±10'
Toe At 20° Turn 1°34' ±30'

Front Camber (at vehicle level)

5.4° -0°58' ±20'
5.9° -0°54' ±20'
6.4° -0°50' ±20'
6.9° -0°47' ±20'
7.4° -0°43' ±20'
7.9° -0°38' ±20'
8.4° -0°34' ±20'
Maximum Deviation 0°20'

NOTE: Measure front axle level and obtain camber value from the table. The front axle level values are displayed by the electronic level measuring instrument in decimal degrees [°]. Example: Front axle level (6.4°) = camber value (-0°50' ± 20')

Front Caster






Procedure:
Measure front and rear axle level and obtain the front axle caster value from the table
Example: Front axle level [-0.8°] + Rear axle level [-1.1°] = Caster value [5°42']
Deduct the correction value (K1) of the corresponding measuring system from the TABLES of caster value and compare result with the measured caster value.
When measuring caster with the electronic measuring systems, the correction values (K1) below are only to be used until the software release of the corresponding measuring system is updated for the model series 220

Measuring system & Correction value
Beissbarth 3'
FMC 21'
Bosch/Hunter 23'

Example:
Measuring system: FMC
Correction value (K1): 21'
Measured front axle level: 6.9°
Measured rear axle level: -0.9°
Caster value from table: 8°56'
Deduct correction value (K1) from the TABLE of caster value: 8°56' - 21' = 8°35'
The MEASURED caster value must be 8°35' ±30

Rear Toe-in (at vehicle level)
+0.1° 0°35' ±7'
-0.4° 0°36' ±7'
-0.9° 0°38' ±7'
-1.4° 0°40' ±7'
-1.9° 0°41' ±7'
Maximum Deviation 0°30'

Rear Camber [not adjustable](at vehicle level)
+0.1° -0°44' ±30'
-0.4° -0°49' ±30'
-0.9° -0°55' ±30'
-1.4° -1°00' ±30'
-1.9° -1°06' ±30'
Maximum Deviation 0°30'

4Matic Models

Vehicle Level

Front Axle 0.0° ±1.5°

When calibrating w/Star Diagnosis 0.5°

Rear Axle -0.6° ±1.0°
Maximum deviation between left & right:
When checking 0.5°
When calibrating w/Star Diagnosis 0.3°

NOTE: To measure vehicle level use (86) Electronic inclination measuring instrument (CM 9606)

-0.0° -0°00' (+10'/-30')
+0.5° -0°55' (+10'/-30')
+1.0° -0°50' (+10'/-30')
+1.5° -0°45' (+10'/-30')
Maximum Deviation 0°20'

NOTE: Measure front axle level and obtain camber value from the table. The front axle level values are displayed by the electronic level measuring instrument in decimal degrees [°]. Example: Front axle level (6.4°) = camber value (-0°50' ± 20')

Front Caster

Procedure:
Measure front and rear axle level and obtain the front axle caster value from the table
Example: Front axle level [-0.8°] + Rear axle level [-1.1°] = Caster value [5°42']






VA=Front Axle Level
HA=Rear Axle Level
Caster tolerance ±30'
The level values are displayed by the electronic clinometer in decimal degrees [°]
