inserting any shim and measure dimension "c".
Insert shims having the thickness of dimension
"c" + 0.2 to 0.5 mm. (Secure clearance of 0.2
to 0.5 mm in the axial direction of the ball joint.)
Tighten the bolts to the specified torque and
check that the ball joint moves smoothly.
a Bolts size: M18 × 4 pieces, 2 places
a Standard shim thickness: 4 mm
