The articulation angles can be calculated using the difference between the respective absolute angles.
Front articulation angle (∠1) :
Transmission to front propeller shaft
Center articulation angle (∠2):
Front to rear propeller shaft
Rear articulation angle (∠3) :
Rear propeller shaft to rear axle differential
Calculate articulation angle:
The angle is positive (+) if the first absolute angle measured is smaller than the second angle measured. The angle is negative (-) if the second absolute angle measured is smaller than the first angle measured.
Calculation example: (1° equivalent to 60')
- Calculate front articulation angle (∠1):
Absolute angle measured at transmission = 1° 55'
Absolute angle measured at front propeller shaft = 2° 10'
This results in an articulation angle difference of +0° 15'.
- Calculate center articulation angle (∠2) :
Absolute angle measured at front propeller shaft = 2° 10'
Absolute angle measured at rear propeller shaft = 2° 45'
This results in an articulation angle difference of +0° 35'.
- Calculate rear articulation angle (∠3) :
Absolute angle measured at rear propeller shaft = 2° 45'
Absolute angle measured at rear axle = 2° 40'
This results in an articulation angle difference of - 0° 05'.
All articulation angle differences should be as close as possible to the center of the relevant tolerance range.
Correcting rear articulation angle (∠3):
In the example, the front and center articulation angles (∠1, ∠2) are within the tolerance range, but the rear articulation angle (∠3) is outside the tolerance range.
To correct the rear articulation angle (∠ 3), fit a shim of 2 mm thickness between the rear axle housing and rubber mount, in addition to any existing shims (arrow).
A 1 mm thick shim changes the articulation angle by approx. 0°15' to 0°20 '.
Shims are available as replacement parts in thicknesses from 1 mm - 4 mm.
If using shims > 2 mm thick, increase the bolt length by 5 mm. If a shim with a thickness > 5 mm is required, check the rubber mounts of the front rear axle carrier suspension for signs of compression and wear; replace if necessary.
Correcting front (∠1) and center articulation angles (∠2)
To correct the articulation angle at the transmission crossmember, fit shop-made shims at the rear engine mount and at the propeller shaft center support bearing.
A 1 mm thick shim changes the articulation angle by approx. 0°10'.
If using shims > 2 mm thick, increase the bolt length by 5 mm.
If a shim with a thickness > 5 mm is required, check the rubber mounts of the engine and transmission mounting for signs of compression and wear; replace if necessary.
Carry out a check measurement again each time the articulation angle is corrected.
