Tech Tip: In-Line Power Steering Filter
Particles not removed during the flushing process or particles
from everyday wear of components and hoses cause valves to stick and block fluid flow. When replacing any power steering component, always flush the entire system and then install an in-line filter.

Alignment & Suspension Specs: 2001-2009 Toyota Prius
The 2000-2009 Toyota Prius requires alignment and suspension service just like any other car on the road. With more than 800,000 Prii (official term for more than one Prius) on of them is bound to end up in your alignment bay.
Tech Tip: Mercedes-Benz Steering System Grinding/Gushing Noises
If you receive customer reports of grinding or gushing noises, which may be heard from the area of the steering system/power steering pump, one of the possible causes may be in the A/C compressor belt drive. This noise is similar to the noise produced by the power steering pump when ingesting air. This type of noise is present at both idle and higher engine speeds, can be heard whether the steering wheel is stationary or moving, and the noise frequency increases with the engine speed.
Tech Tip: Old-School Method of Flushing Still the Best
After replacing power steering components, technicians may experience a lack of assist, intermittent assist problems or noisy operation. This may be caused by the system not being completely flushed of all debris and contamination.
Tech Feature: Solving Steering Wander
As frustrating as diagnosing steering wander complaints might be, most can be solved by thoroughly inspecting the physical condition of the vehicle. In the following text, I’ll cover some of the most common causes of steering wander and how to detect them during an undercar inspection.
Alignment & Suspension Specs: 2005-’10 Ford Mustang (Plus Shelby)
In 2005, Ford introduced a new Mustang with an all-new platform and clean-sheet design. While the formula of a live axle rear and MacPherson strut front end were the same from the previous model, Ford refined the design. These changes make for a vehicle that is easier to align and diagnose compared to the previous generation.
Tech Tip: Remote Power Steering Pump Reservoirs
This Tech Tip covers power steering-equipped vehicles with a remote mounted pump reservoir. Technicians may find that the replacement power steering pump produces no pressure, pump is noisy or fluid over-flows after shutdown. This may be caused by restricted flow out of reservoir or an air-bound system due to a restriction in the system.
Tech Tip: 10 Steps to Trouble-Shoot Power Steering Pumps
What are the things that must be done to ensure successful diagnosis, installation and testing of a replacement power
steering pump? The following 10 questions outline the most common causes of failure, trouble-shooting suggestions,
diagnostic tips, and proven installation procedures and practices.
GM Tech Tip: Electric Power Steering Hard to Turn
The power steering inoperative or hard to turn. The vehicle will also have a “Power Steering Message Displayed” on DIC and codes C0176, C0475, C0476, C0550, U2105 or U2107 set. The following diagnostics might be helpful if the vehicle exhibits these condition(s)
Tech Tip: Hyundai Power Steering Pump Whining Noise
Before replacing a power steering oil pump on a 2003 Accent for a “whining” noise condition, check the oil pump reservoir filter screen for contamination. If the filter screen at the bottom of the oil pump reservoir is clogged, it may cause the pump to aerate and produce a “whining” noise.
Installation Errors Increase Risk of Power Steering Pump Returns
Replacing a power steering pump is a fairly simple job on most vehicles. But if the installation is not done correctly, it may result in noisy operation, reduced power assist or no power assist at all, according to Mike Simon of Ixetic, a manufacturer of power steering pumps.
