5. Change the outer races of the steering knuckle bearings.
Apply compound Loctite 290 to the outer sides of the races.
Apply grease to the bearing surface and fill the bearing loca-
tion with grease. Fit the spacer rings in front of the races. Apply
Loctite 290 to the spacer rings.
6. Remove the bearings from the king pins and fit new bear-
ings. Grease bearing rollers. Fit new seals into the king pin
holes inside the knuckle.Grease the seals.
7. Adjust the steering knuckle bearing preload as follows:
--- Press the king pins into place using a screw clamp and
measure the distance between the inner surfaces of the king
pin cover (measurement N e.g. 258,50 mm)
--- On the knuckle housing measure the distance between the
surfaces as shown in the figure above (measurement M e.g.
256,85)
--- Calculate the number of shims required (measurement S),
taking into accountthefact that the bearings are preloadedby
0,6 mm (measurement P).
S = N --- M --- P (=258,50---256,85---0,6=1,05)
8. Fit the required number of shims under the upper king pin.
9. Fit the steering knuckle onto the axle housing (see Op 642
1A;13---15).
