Power Steering Service

For most of us, it is hard to remember life without power steering – cranking those great big steering wheels was quite the workout.  Now with Power Steering standard in all vehicles, we have to go to the gym to tone our arms. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine – a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump. These hoses can develop leaks, so it is a good idea to inspect them at every oil change. Low or dirty Power Steering Fluid can damage the power steering pump. That is why a fluid level & inspection is always part always part of every oil change service we perform at John’s Auto Care. The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so it needs to be flushed from time to time. Many manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the maintenance schedule for many.   When in doubt, every 25,000 miles or two years is a good fallback. Your John’s Auto Care service center will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff. Here are some warning signs of trouble with your power steering: It’s harder to turn the wheel, there’s erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast. Other steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at John’s Auto Care will reveal bent or damaged steering components. Most SUV’s, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service. The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. It’s also recommend the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners’ manual maintenance schedule. It’s usually required around every two years or 40,000 miles. If you drive through water, the bearings will need service more often.
