Medium-Duty Truck Clutch Repair
What is a medium-duty truck? The industry defines it as a vehicle with a Gross Vehicle Weight of 14,000 to 26,000 lbs. At 14,000 lbs., most heavy-duty one-ton trucks qualify as a medium duty vehicle. In light- and medium-duty trucks, the automatic transmission is ever increasing in popularity and numbers. So why am I talking
Brake Tech Update: Uncovering Brake Fluid Leaks on Acura Integras
The brake fluid level on 1994 Integras may be low in the ABS reservoir, and fluid may appear to be leaking from under the label on the ABS accumulator. The likely cause is that the ABS accumulator internal O-ring is damaged, allowing brake fluid to leak out. Diagnosis: Remove the label from the ABS accumulator.
Creating the Right Alignment: Performing a Custom Alignment
Customer satisfaction. That’s the one thing you always want to achieve when you align a customer’s vehicle. Satisfied usually means no steering pull, no steering wander, no steering shimmy, no off-center steering wheel – and no comebacks! An alignment provides other benefits, too, such as reduced rolling resistance (which helps fuel economy) and reduced tire
Brake System Service: Eliminating Noise and Vibration Problems
Brake noise and vibration are two things few people will tolerate for very long ‹ especially owners of high-performance European sports cars and luxury sedans that are renowned for their eye-popping stopping power. People who spend upward of $30,000 or more for an upscale Asian or European nameplate usually expect their brakes to be quiet.
Understanding Seals
It has been a long drive to the lake. The driver carefully backs the trailer down the boat ramp. As the axles hit the water, the hot wheel bearing hubs hit the water. As the bearings’ heat is quenched by the lake water on the outside of the hub, the rapidly contracting air and lubricants
Missed Services
Uncovering missed service can bring an instant profit, while at the same time resulting in customer gratification. Unfortunately, some services are often overlooked in our daily routine. It’s easy to gain tunnel vision in this business, only fixing what the car came in for, while ignoring the rest of the vehicle. Whether it’s because of
Cracking the Code, Understand Friction Material Edge Codes
Just about every brake pad or shoe you install has a cryptic code printed on the side of the friction material. As a technician, being able to read this code is just as important as the Dewy Decimal system is to a librarian. The “Edge Code” can tell you information about the product you are
Friction Material Selection
Because today’s lighter and more friction-efficient disc brakes have become very sensitive to differences in friction materials, the issue of selecting a quality brake pad is becoming increasingly relevant to the quality-conscious installer. To illustrate, aftermarket manufacturers of high-performance disc brakes offer literally dozens of racing pads that are qualitatively equal, but vary widely in
Always Inspect Hardware During Brake Repairs
Though it isn’t required, many brake experts recommend replacing the drum hardware when the brakes are relined to restore the brakes to like-new condition. But often the hardware isn’t replaced because it doesn’t seem necessary. Unless the hardware is badly corroded or shows obvious signs of stress, like severe heat discoloration or other visible damage,
Volkswagen New Beetle Maintenance Essentials
The New Beetle has been around for several years now, and except for the classic shape, it’s not the Beetle of old. Unlike its ancestor, this New Beetle is conventional, modern and sophisticated. It has all of the bells and whistles of other current models, the performance and handling of a conventional front-wheel-drive car, and
Ball Joints & Bushings: Worn Components Take Their Toll on Advanced Suspension Technologies
Too often, shop owners and technicians alike assume that suspension systems haven’t changed much in the past 20 years. In reality, nothing could be farther from the truth because today’s import vehicle may incorporate a number of technologies that can be affected by worn steering and suspension components. To illustrate, we’re beginning to see electronic
Checking into Mode $06
Mode 06 is the actual system test data that OBD II looks at when it decides to set a pending code or a current fault code. If the test data is within the limits established by the vehicle manufacturer, the item gets a PASS and no codes are set. But if a value is out of range, OBD II flags it with a FAIL and keeps an eye on the component until the system monitor has run at least twice. Then, if the problem is still there, a DTC is set and the MIL light comes on.
