Place joint housing (9) with drive shaft onto steering knuckle.

Slide 2 mm wide adjusting ring (1) onto upper kingpin (5).
Install upper kingpin (5) without shims.
Slide 6 mm wide adjusting ring (3) and 4 mm wide adjusting ring (4) onto lower kingpin (6).
Note model year dependent change in diameter of lower kingpin (6) and 6 mm wide adjusting ring (3).

The lower kingpin (6) has an interference fit on the last 5 mm. The steering control arm is fixed in the joint housing by pilot bushings with lengths of 5 mm. Slide a 6 mm wide adjusting ring (3) onto lower kingpin (6) so that the measurement is not distorted by jamming. The 4 mm wide adjusting ring (4) is used to facilitate measuring distance B (B) with a feeler gauge.

Install steering control arm without shims.
Mount C-clamp and close far enough until no more play is registered in the steering knuckle bearing.
In doing so move the joint housing to and fro so that the bearing can settle.
Measure distance A (A) and distance B (B) using feeler gauge.
Supplementary dimension C is the difference of the adjusting rings plus the pretension.
Determine thickness of shims at top of steering knuckle.
Example:

Supplementary dimension C 2.15 mm

- Distance A (A) - 1.30 mm

-------------------------

--------

= Thickness of shims = 0.85 mm
Determine thickness of shims at bottom of steering knuckle.
Example:

Supplementary dimension C 2.15 mm

- Distance B (B) - 1.10 mm

-------------------------

--------

= Thickness of shims = 1.05 mm
