How Power Steering Specialists Diagnose Steering Pull

There are several causes for Steering pull and diagnosing the cause is very important for safety reasons and for the vehicles roadworthiness.

Road Test Assessment

Pull is constant even when the brakes are applied. In other words, pull is not ‘some time’ and then not other times. On a straight road pull occurs at the same speed time and speed as on other straight roads. This enables a test to be set up in order to duplicate the problem on other occasions in order to enable full diagnosis.

Tyre Pressure and Condition Check

Typically uneven tyre pressures are the most common cause of pull and therefore are checked first. In addition, worn tyres are checked for unusual wear, which can be indicative of underlying geometry problems.

Wheel Alignment Measurement

Alignment is measured using a four-wheel laser. Steering pull can be caused by as little as a 1mm difference in toe setting between the two front wheels.

Caster and Camber Angle Checks

The caster angle – This is a very common problem, particularly after a kerb strike and causes a steady pull when toe is set correctly. This is covered by UK vehicle safety standards for steering geometry and therefore treated as a roadworthiness matter and not as a matter of comfort, For Power Steering Specialists, visit https://westernpowersteering.co.uk/

Once all checks have been completed then the findings can be assessed to see if any repair is required.
