Torque And Runout: Measure Twice, Install Once
There are two critical measurements when installing a modern hub unit or cartridge bearing: torque and runout in the flange. Ignoring these critical numbers to save time will only lead to more comebacks and angry customers.
Understanding Friction And Formulations
Friction is the force resisting the relative motion of elements sliding against each other. In the case of cars and trucks, it is the brake pads pushing against a rotor that changes kinetic energy into heat.
New Or Old, Rotors Must Be Measured
Installing new rotors without ever measuring and documenting the condition of the old rotor is like playing chicken with a comeback. Sooner rather than later, you will find a vehicle that will not be magically fixed by a new set of rotors. In fact, the new rotors may cause even more problems and lead to an unsatisfied customer.
Troubleshooting ABS Modulator Mechanical Problems
Mechanical issues with the ABS modulator, or hydraulic control units (HCU), are rare, but they can happen. With more and more vehicles on the roads with older ABS systems that have not seen proper brake fluid maintenance, mechanical issues are becoming more common.
Power Steering Hoses: Inspection And Repair
The life of power steering hoses is not easy. Power steering hoses must endure some of the highest pressures and temperatures under the hood. Coupled with ozone, oil and solvents attacking the outer layers of these power steering hoses, it is easy to see why some hoses fail.
False ABS, ESC Activation Causes And Cures
The first mass-produced anti-lock braking systems (ABS) were introduced in 1985. By 2008, almost every passenger vehicle came standard with ABS. Next, electronic stability control (ESC) became a mandated safety feature for the 2012 model year. Along with all these advancements have come false activation complaints.
Component Connection: Press-in Bearings With Fewer Comebacks
Servicing the increasing number of vehicles equipped with pressed-in wheel bearings requires a little bit more finesse and tools when compared to hub units or tapered roller bearings. However, with the right tools and information, these jobs can be money-makers.
