Tech Tip: Diagnosing Starting/Charging Systems
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the same skills.

Tech Tip: Diagnosing and Servicing Manual Transmissions
Manual gearboxes are relatively trouble-free and long-lived, provided they are not abused too severely. The clutch, however, is a wear component. With every shift the clutch must be disengaged and engaged. Stop-and-go driving in heavy traffic is especially hard on a clutch because the driver is always riding the clutch pedal. After millions of such cycles, the clutch eventually wears out. It may start to slip, chatter or make noise.

Tech Tip: Replacing Wheel Bearing Hubs Equipped with Wheel Speed Sensors
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside world.
Tech Tip: Reconditioning Connecting Rods
When you’re looking at connecting rods and considering returning them to service, there are many things you must consider. They are one of the most critical pieces of the engine puzzle and under great strain when in operation, so you must pay attention to the details during the rebuilding process.
Acura Tech Tip: Diagnosing Front Suspension Knock
A knocking noise from the front of any vehicle can be a cause for concern. If the vehicle is an old pickup truck with 150,000 miles of hard off-road use, noises usually come with the territory and are sometimes acceptable. But, if the vehicle is a 1996-98 Acura RL, not only will the owner notice it, they will probably want it fixed right away.
Tech Tip: New Shocks and Struts Can Improve Vehicle Handling
Shock absorbers and struts dampen the motions of the suspension to provide a smooth, comfortable and safe ride. Some OEM shocks have electronic valving that allows the driver or a body control module to adjust the dampening characteristics of the shocks or struts to changing driving conditions. Electronic dampers may use a solenoid or an electric stepper motor for this purpose. The latest technology is to use a special "rheological" magnetic fluid that changes its viscosity when a current is passed through it.
