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
