Compare Porsche steering rack repair quotes from specialist garages

Porsche is known for its high-performance luxury sports vehicles - the best-selling model being the Cayenne. The company's founder, Ferdinand Porsche, created the world's first hybrid vehicle in 1899. It was called the Lohner-Porsche and was driven by electricity with a fuel-powered generator to charge the batteries, though it never made it into production.

Porsche continues to break new ground to this day; in 2017, the Cayenne S Diesel model earned the Guinness World Record for towing the heaviest vehicle, pulling an enormous Airbus A380 aeroplane weighing 285 tonnes.

Rack and pinion steering relies on a gear set to convert the turning movement of the steering wheel into the motion required to turn the wheels. When this system is combined with power steering, the configuration changes slightly to include a cylinder with a piston in the middle.

The three top reasons for a steering rack repair or replacement are cracked rubber lines and hoses, loose connections, and failed seals between the steering column and rack and pinion.

Common signs of a problem include:

• Leaking power steering fluid
• Loose or inconsistent steering
