Squealing or hard steering? We can help!
September 10th, 2015
Today's cars typically have either the standard mechanical (reciprocating ball) steering or rack and pinion steering. The standard mechanical steering can be either power-assisted or non-power. Rack and pinion is almost always power-assisted, although there are rare cases where it is not.
Power steering is a system that is often overlooked in routine maintenance. But, imagine how driving would be without it! Over time, power steering fluid degrades. When this happens, steering is noticeably more difficult.
Fluid contamination is the leading cause of component wear in power steering systems. Debris from component wear becomes suspended in the power steering fluid. As this contaminated fluid is pumped through the power steering system under very high pressure, it causes more abrasive wear in the pump and rack assembly, which leads to pump noise, erratic steering and ...
