Electric Power Steering
When a technology like hydraulic power steering has been around for so long, it is difficult for technicians and even the training establishment to deal with a new system like electric power steering. These systems abandon fluid logic for electronic logic. It is not a simple exchange of power steering fluid for magnetism. Wrapping one’s
Shaken, Not Steered
Wouldn’t it be great if various vibrations in the car were something that we could measure, sort through, select one and assign numbers to it that can be used to find its source? Wouldn’t be even better if we could determine by the numbers whether the vibration was a balance issue or excessive runout with
Alignment Update, Expensive Parking
It is a misconception that the number of bays determines success. Instead, it is the number of vehicles a bay can service in a day and the profitability of the repair order that often determines success. Adding extra bays to your shop is one way to add capacity, but it does not address the issue
Steering Position Sensors: Keeping on Track
The steering position sensor’s basic function is to monitor the driver’s steering inputs. This includes the angle of the steering wheel and/or the rate at which the driver is turning the wheel.

Diagnostic Solutions: Steering Gears
Keeping Your Customers’ Vehicles on The Straight & Narrow Modern automotive steering gears evolved from the quaint tiller-controlled steering systems used in the first automobiles to the hydraulically controlled systems now used in most import vehicles.

It’s 1956 and the 20-inch-diameter steering wheel on a Chevrolet Bel Air or Ford Fairlane provided the leverage to steer the wheels. But, it was especially difficult to turn the steering wheel when the vehicle was stopped. Turning the wheel required a certain amount of upper body strength that was given by God to truck
Steering Stabilizers: Suspension Geometry
Big rims or tires can look good and give a vehicle a unique look. But what is invisible becomes real ugly is the alignment and suspension angles that become altered. Also, that extra weight in stylist alloy rims or thick off-road tires can create a gyroscopic problem. Lifting Why do people lift trucks? The primary
A Brief History
In 1931, people thought Edward S. Babcox was insane for launching a magazine in the middle of the great depression. But, 75 years and almost 900 issues later, BRAKE & FRONT END is still going strong. For the past few months, I have been reading back issues of BRAKE & FRONT END non-stop. In musty
Alignment Equipment

Suspension Vibration Diagnosis
The song “Good Vibrations” by the Beach Boys may have been a big hit in its day, but there’s no such thing as good vibrations or noise when it comes to a customer’s vehicle. Vibrations are annoying and may be a warning signal that something is amiss. So don’t ignore such symptoms. Investigate any unusual
