How does a power steering system work?

Most power steering systems use a belt-driven pump to provide hydraulic pressure, which is generated by a rotary-vane pump, in turn driven by the vehicle engine. The belt may start to make a noise if the tension is low, the system is contaminated, or it begins to vibrate. Pressure in the hydraulic fluid increases as the engine speed does, and so a relief valve prevents over pressurisation. Pressure is transferred to the steering gear through hoses, which may eventually crack, bulge, soften or show signs of abrasion.

Tyres and power steering

The performance of your power steering relies heavily on the correct use and placement of your tyres. Mixing size or type of tyres on the same axle can have an impact. In general, if replacing only two tyres on front or rear drive vehicles, then the new tyres should be placed on the rear. Likewise, if radials and non-radials are on the same vehicle, then the radials must be on the rear. Ensuring that your wheels are properly aligned will extend their lifespan and minimise power steering issues associated with improper the placement.

Your power steering repairer

At Complete Alignments, we know all there is to know about power steering. Power steering is  often under appreciated until something goes wrong. Modern vehicles would be extremely difficult to manoeuvre, particularly at low speeds, with manual steering only. If you notice an issue, then we will complete an assessment and fault diagnosis. Some of our power steering services involve pressure and flow testing, accident damage repairs, CSA change over steering boxes, drag link setting and replacement, tie rod and rod ends replacement, king pin repairs, steering shaft repairs, replacement and phasing, and line and pump repairs and replacement.
