To adjust the clearance in the worm bearings, turn the steering wheel to the left by 1-1.5 turns, unscrew the bolts securing the bottom cover 19 and drain the oil from the steering gear housing. Remove the bottom cover, remove one of the shims 18 or replace it with a thinner one.
Note. Shims are supplied as spares in 0.10 and 0.15 mm thicknesses.
After securing the bottom cover, check again if there is any axial movement of the worm in the bearings. If there is no movement, fill the steering gear housing with 0.215 liters of gear oil.
Check the steering force by placing the front wheels on a smooth metal plate. It should not exceed 196 N (20 kgf), 245* N (25* kgf).
