Tech Tip: Diagnose and Repair ABS on Ford Trucks
As you are all very well aware, occasionally anti-lock brake system (ABS) malfunctions can be very complicated and hard to diagnose. In the case of some late-model Ford truck anti-lock brake systems, however, several malfunctions may have a very simple solution.
Brake Tech Tip: Noise/Creak During Slow Speed Braking
Some customers may comment on a creak-type noise occurring when applying the brakes. It is usually heard only during slow speed brake maneuvers. If this condition exists, it should be able to be duplicated when the vehicle is not moving by depressing the brake and listening for the noise from the wheel-well/caliper area.
Tech Tip: What Does SAE 10W-30 Actually Mean?
We all know to check the owner’s manual to find out which weight oil should be used in the engine of a vehicle, and also generally know to only use motor oils with American Petroleum Institute Certification, designated by the starburst displayed clearly on the container, in most vehicles. But what really is the difference between a SAE 10W-30 and a SAE 10W-40, or for that case, SAE 0W-20 motor oil?
Tech Tip: Servicing Dual-Mass Flywheels
A dual-mass flywheel is essentially two flywheels in one that provides some spring cushioning to dampen torsional crankshaft vibrations and shock loading when the clutch is engaged. Think of it as a flywheel with some "give."
Tech Tip: Chrysler Engine Mount Noise
I know the majority of you auto techs are extremely proficient at finding and repairing sources of strange and unusual noises. Although chasing these audible emissions can be time consuming and without a doubt aggravating, the customer’s concerns are usually valid and can often be of monumental importance to them.
Tech Tip: Watch Out for Ford Trucks that Blow Out Spark Plugs
One service issue technicians should be on the look out for is late-model Ford trucks (1997 to 2004 Ford F-Series, Expeditions and Excursions) that are reportedly blowing out spark plugs. The problem seems to occur most often on 5.4L Triton engines, but may also occur on other V6, V8 and V10 engines in these vehicles.

Under Pressure
According to the U.S Department of Transportation, cooling system failures are the number one cause of vehicle breakdowns on the highway. Many of these breakdowns are attributed to coolant leaks (hoses, radiators, bad radiator caps, etc.), water pump failures, thermostat failures and defective cooling fans. An industry survey conducted in 2003 by 1-800-Radiator reported that
Tech Tip: Removing and Installing a Wheel Hub Bearing
Proper wheel hub bearing removal and installation procedures can enhance the performance and life of hubs, axles, wheels, brakes and other components. Following are general recommendations for removing and installing wheel hub bearings.
Tech Tip: Motor Mounts – Supporting the Engine and Transmission
Motor mounts are not a very glamorous product, but they do have an important function: They support the engine and transmission, and dampen noise and vibration. The mounts isolate the engine and transmission from the chassis so vibrations and noise are not transmitted to the rest of the vehicle.
Tech Tip: Motor Mounts – An Opportunity for an Add-On
Often-overlooked engine components that may need to be replaced when installing a remanufactured engine are motor mounts. These rubber mounts can deteriorate, collapse and/or separate with age. Fluid-filled "hydraulic" type mounts can often leak, allowing annoying engine vibrations to be transmitted to the chassis.
Tech Tips: Brake Lubricants – High Temperatures Require High Performance Products
When it comes to brake lubricants, grease is a dirty word. Brake lubricants are specially-formulated products that are NOT the same as ordinary chassis grease or even multi-purpose grease.
