Dynamic properties and driving safety depend on how reliably the wheels are guided in the required direction

The steering should be as sensitive as possible to enable precise target steering.

It is consistent with the axles and the ratio of the angles of rotation of the steered wheels.

- Cause of malfunction


Increased steering wheel freeplay angle:

- Increased clearance in the engagement of the nut-sector pair

Adjust the engagement of the nut-sector pair

- The appearance of a gap in the propeller bearings

Adjust screw bearing

- Excessive wear of the part of the hinges of the rods and their fastening

Replace worn parts

- Increased wheel hub play

Adjust wheel bearing clearance

- Loosening the wedges of the forks and the nuts of the bipod

Tighten loose nuts

Steering, squeaking or clicking:

- Excessive wear of the screw or shaft-sector, chipping or dents on their surface

Replace screw nut or sector shaft

Weak fixation of the steering column:

- Loosening the column locking mechanism

Adjust column locking mechanism

Increased steering force "heavy steering wheel":

- Kingpin bushing scuff

Replace bushings and king pin

- Turning the king pin bushings in the knuckle bosses

Replace bushings and kingpin

- Pollution of the pivot bearing (when turning the wheels, a creak is heard in the thrust bearing)

Rinse the thrust bearing through a grease gun with a mixture of 50% kerosene and 50% gear oil.

Lubricate the support bearing through the grease fitting until grease comes out from under the seal

Grease leaking from the steering gear:

- Wear or loss of elasticity of the stuffing box and steering gear seals

Replace worn oil seal and O-rings

Steering column play:

- Axial movement of the steering wheel shaft relative to the casings

Replace worn steering column bearing bushings
