SKF Tech Tip: Replacing A Wheel Hub Flange, Bearing Guide
Damaged parts or improper torquing can cause premature hub failure and issues with overall vehicle performance.
Raybestos Tech Tip: Low Brake Pedal From Bad Wheel Bearing
When a vehicle comes into a shop with a low or spongy brake pedal, what is your first thought? Chances are you think it is a problem in the hydraulic system. It could be a faulty master cylinder, a leak in the brake lines or a bad caliper.
KYB Tech Tip: Use The Supplied Nut
For production purposes and quality consistency, KYB may supply a special nut that matches the new mounting stud.
Mevotech Tech Tip: Installing Directional Ball Joints
Some ball joints must be installed in a specific orientation to function correctly. These ball joints are designed to allow for a large amount of ball stud swing in the cross-car or side-to-side direction as the suspension travels up and down.
SKF Tech Tip: Reusing Circlips
Circlip retainers are important to help maintain the proper seating and function of the wheel bearing. Depending on the vehicle application, there may be one or two circlips that facilitate retention of the bearing.
Windshield Wiper Blade Revival
Most OEMs and wiper manufacturers recommend a wiper blade replacement interval every 6-12 months, but wiper life can vary greatly depending on the region of the country and the conditions under which the vehicle is operated. Exposure to intense sunlight and heat can increase the degradation process, as can exposure to dirt and debris. The
Sealing Modern Water Pumps
Over the past 20 years, we have seen water pumps and cooling systems evolve to improve start-up emissions. We have also seen a revolution in the material used for engine blocks, cylinder heads and cooling system components. Today, coolant may flow through an iron block, aluminum cylinder head and plastic thermostat housing.
Trusting Your Torque Wrench
The torque specifications for components are much more exact now. Fastener requirements are also changing such that nuts and bolts are more vehicle specific, so there is no more running to the backroom if you need a replacement.
Summer Vacation Insurance: Catch a System Failure Before it Interrupts Your Customers’ Travel Plans
With many customers scheduling summer vacation road trips, it is important to check vehicles’ belts and hoses before they get on the road.
The Engine Thermostat: Understanding Electronically Assisted Thermostats
The engine thermostat plays an important role in increasing engine combustion efficiency and reducing emissions. But today’s electrically assisted (also called “map-controlled”) thermostats provide broader and faster operation than the traditional engine thermostat.
Speed Density Systems: Performance Reliability
For many years, most of us believed that the mass airflow system provided the most accurate measurement of an engine’s intake airflow. For one thing, not too many things can go wrong with a system that produces a single voltage or frequency input that indicates to the ECM an exact value of intake airflow in grams per second.
Air Ride Dryer Diagnostics
The dryer on most air ride systems contains a moisture-absorbing desiccant, such as silica or specialized clay. All desiccants have a limited lifespan; they can absorb only a certain amount of water. Once the desiccant is saturated, the air coming into the system is no longer treated, and water can then accumulate in the system.
