In this article we will look at possible faults in the steering control of a Gazelle car and how to troubleshoot problems

Possible malfunctions of steering without power steering

- Cause of malfunction

Elimination method

Increased steering wheel free play 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 screw bearings

Adjust the screw bearing

- Excessive wear of the rod hinges and their fastenings

Replace worn parts

- Increased play of wheel hubs

Adjust the clearance in the wheel hub bearings

- Loosening the fork mounting wedges and the bipod mounting nut

Tighten loose nuts

Sticking, squeaking or clicking in the steering mechanism:

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

Replace the screw nut or sector shaft

Weak fixation of the steering column:

- Loosening the column fixation mechanism

Adjust the column fixation mechanism

Increased steering effort "heavy steering":

- Pivot bushings scuffed

Replace bushings and kingpin

- Rotating the king pin bushings in the knuckle bosses

Replace bushings and kingpin

- Contamination of the king pin support bearing (when turning the wheels you can hear a creaking sound in the support bearing)

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

Lubricate the support bearing through the grease nipple until grease appears from under the seal

Lubricant leak from the steering mechanism:

- Wear or loss of elasticity of the oil seal and steering gear seals

Replace worn oil seal and rubber sealing rings

Steering column play:

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

Replace worn steering column shaft bearing bushings

Diagnosis of power steering faults

- Cause of malfunction

Elimination method

Continuous noise from the pump:

- Bearings are worn

Replace bearings

The amplifier does not work or its efficiency is low (increased effort on the steering wheel):

- The filter in the tank is clogged

Replace the filter (on some engines the filter is replaced with the tank assembly) and, preferably, the fluid

- The flow and safety valves are clogged

Rinse the valves and pump

- The belt slips along the pump pulley

Tighten or replace the belt

- Liquid of inappropriate viscosity is poured (as a rule, its viscosity is low)

Replace the fluid

The steering wheel turns in one direction much easier than in the other:

- Clogged hydraulic system

Flush the hydraulic system and amplifier

- Amplifier defect: destruction of its parts, valve leakage

Replace the amplifier assembly

Fluid leakage from the system:

- Seals are worn

Replace the seals

- Cracks in hoses, their clamps are not tightened tightly

Tighten the clamps, replace the rods

- Leaking from under the amplifier or pump covers

Replace gaskets, rubber rings

- Leak through technological holes in the pump housing (plugs squeezed out)

Press in new plugs or replace the pump

- Increased pressure in the system due to the flow valve jamming in the closed position

Fix the problem or replace the pump

- Excessive fluid level in the tank

Take off excess liquid with a syringe or rubber bulb

Low directional stability at high speed:

- Improper adjustment of the propeller bearings and the nut-rack-shaft-sector steering gear pair

Adjust the gaps between the parts
