IMPORTANT NOTE :
To carry out this adjustment it is essential to
use tool 6312 T class 2 which is required for fitting
lower wheelorm on front axle.

lower arm and castor angle adjusting shims (3 )
b)
Determining distribution of shims :
NOTES :
A minimum of 1 shim should be set on each
side of the wheelarm.
- Movement of
1 mm will vary castor angle by
15’.
Total thickness of shims fitted must corres-
pond to the total thickness of shims found on
dismantling, in order to maintain the correct
assembly of the wheelarm in axle unit.
