Steering faults, along with brake faults, are the most serious automobile faults. With the widespread use of rack and pinion steering on modern passenger cars, the list of steering faults has been greatly reduced. But sometimes it’s still easier to refer to here: https://scrapcar.cash/what-paperwork-do-i-need-to-scrap-a-car/.
Steering faults include:
wear of the transmission pair (“pinion-rack”);
leakage of the steering mechanism;
Wear or destruction of the steering shaft bearing;
Wear of the joint on the steering link rod end.
The most common steering malfunction is wear of the ball joint of the steering link lug.
Steering system malfunctions should be mentioned separately. The following power steering malfunctions are distinguished:
wear of the pump shaft bearing;
slipping of the pump drive belt;
low fluid level in the tank;
clogging of drive elements (filter element, pump valve, etc.)
loose or damaged hoses.
The main causes of steering faults are:
poor quality of roads;
violation of operating rules (change of service intervals, use of poor-quality working fluid and components);
unqualified maintenance and repair of the system;
the service life of the system is limited.
Various deviations from wheel performance (tire pressure, balancing, tire wear, hub bearing wear) may also be the cause of steering faults.
The onset of steering malfunction is usually indicated by various external signs, the main ones being:
knocking in the steering;
Bouncing of the steering wheel;
Increased play of the steering wheel;
Tight rotation of the steering wheel;
noise in power steering;
For information, backlash is the idle movement of the steering wheel, i.e. the movement in which the turn is not made.
A few words about leaking fluid. Fluid leakage in the steering components is not as obvious as for cooling system malfunctions – you will not see a puddle under the car. You can determine the leakage with a detailed inspection of the system, with the faulty element looks wet, the specialists also say – fogged.
