Electronic Power Steering: More Common Than Uncommon
Electric power steering (EPS) is coming to your shop on a lot more cars and trucks ranging from the Chevy Cobalt to the latest Ford F-150. So, there is no avoiding EPS diagnostics or repair. Most EPS setups are more than the rack and motor; they are a highly connected system that rivals any engine when it comes to diagnostics.
Ford Tech Tip: Sustained Steering Wheel Oscillation Above 45 MPH
Some 2017-2019 F-250/F-350 4WD vehicles built on or before July 31st, 2018, may exhibit a sustained steering wheel oscillation after driving over rough pavement or an expansion joint above 45 mph. Follow the Service Procedure steps to correct the condition.
Electric Power Steering: Mating Electrical And Mechanical Diagnostics
Most electric power steering system modules are on the high-speed CAN network with the engine control, ABS and transmission control modules. Some vehicles will also include the body control module and other modules that are critical to the safety of the vehicle. These modules share a lot of data to make sure the driver does not notice when the electric power steering is working.

Electric Power Steering Advancements
Electric power assist does more than add force in either direction; it can push back to improve handling and driver comfort. These corrections could be as innocuous as adding a little assist for road crown, or as obvious as the vehicle steering on its own. But, a lot of the improvements in electric power steering have mostly gone unnoticed by the driver and even the technician.

Mazda Tech Tip: Vibration Felt Through The Floor/Seat/Steering Wheel
Some customers may complain about a vibration that is felt through the floor, seat and/or steering wheel while driving under moderate acceleration, at speeds of approximately 25-30 mph (40-50 km/h). The vibration is more noticeable when driving on smooth, flat roads.
Steering And Suspension Inspection: Keeping The Angles In Line With Ackermann
Most people consider the common tire rod to be low tech. But, when you consider how front suspensions have evolved from straight axles to independent designs, the tie rod has had to adapt to new angles and geometry.
Electronic Power Steering: More Than Just An Assist
Electric power steering is quickly becoming a standard feature on new vehicles, but it’s not an emerging technology. It’s been in the field for the better part of two decades. Now, electric power steering has continued to advance by making autonomous safety features possible.
What’s New With Functional Fluids?
Late-model vehicle technology is changing. Wider tires, active safety systems and AWD technology are not only influencing how vehicles perform, but also the service and maintenance requirements of their functional fluids.
