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
Thrust Angle
The thrust angle is an imaginary line drawn perpendicular to the rear axle’s centerline. It compares the direction that the rear axle is aimed with the centerline of the vehicle. It also confirms if the rear axle is parallel to its front axle and that the wheelbase on both sides of the vehicle is the
Collision-Related Alignments: It’s All in the Angles
src=”elements/100656.gif” width=”180″ height=”131″ alt=”” border=”0″ align=”baseline” /> When a vehicle is involved in an accident, extreme forces are placed upon the design characteristics of the structure, as well as all related and attached system components. This energy management of the collision forces is what began the need for technical training and the formation of I-CAR.
Tire Tech
Coupled Forces Why using less weight is not a shortcut In our July issue on page 26, the article titled “Less Weight, Great Balance” (or at www.brakeandfrontend.com) answered a lot of questions, but it also brought up some new ones. The article was on the new technology that many new balancers are featuring that can
A Brief History of the Steering Wheel & Power Steering
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
Tie Rod Geometry
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. Keeping it on the road was simple with the straight
Wheel Alignment,: Advances in Alignment Equipment Increase Productivity and Profit

Loss Leader: Lost Cause?
It seems like there are always certain services that are routinely performed by repair facilities at a loss. Sure, they might generate enough revenue to pay for the direct expenses of doing the job, such as parts and technician labor, however, they often fail to make their needed contribution to the overhead expenses of owning
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
