Dodge Tech Tip: Rear Brake Cyclic Rubbing Sound
A cyclic swoosh, squawk, squeak or grunt sound from the rear of the vehicle may be heard during medium to light brake application on vehicles equipped with rear drum brakes. The sound will be related to the speed at which the tire/wheel turns (one sound per revolution of the tire/wheel). If the vehicle operator describes the subject Symptom/Condition, test drive the vehicle to verify.
Tech Tip: Putting The ‘Brakes’ on a Common Customer Complaint
Warped rotors are probably one of the most common complaints made to shop owners and technicians who repair and service brake systems. The less confident or sophisticated driver may complain that when he hits the brakes, "my pedal pulses," "the vehicle chucks during a stop" or "it shakes my teeth during braking." Generally, a quick turn of the rotors and some fresh pads cures the pulsation complaint and down the road goes another satisfied customer.
Chevy Silverado Tech Tip: ABS Light Comes on at 40-50 mph
At speeds over 40-50 mph, the ABS and brake indicators come on, and the fuel and volt gauges sometimes drop low at the same time. The technician had already verified the condition and checked for codes before calling Identifix. He found code C0237 (rear wheel speed signal erratic) stored as a history code, but it had not reappeared for him.
Tech Tip: Diagnosing a Slow Cranking Starter or No Crank at All
A slow cranking starter or no crank at all may be caused by a faulty ground that prevents full voltage to the starter motor. Most people assume the starter is grounded because it is bolted to the engine. However, that does not mean it’s grounded properly. The combination of road dirt, salt corrosion, engine heat and vehicle age can prevent a good starter-to-engine ground (metal-to-metal contact).
Tech Tip: GF-5 Motor Oil Specifications
As engine technology advances to produce more efficient engines, motor oil must continue to meet the increasing demands for lubricating these precision-made engines. Development of the next specification of gasoline-fuel (GF) motor oil began only months after the latest specification, GF-4, became available in 2004.
Nondirectional Rotor Finishes: Do You Need Them?
You have probably heard that nondirectional rotor finishes can lessen the risk of new brake pads squealing. They can, but do you really need to apply a nondirectional finish to freshly turned rotors. And what about new rotors? Should you give them a nondirectional finish if they don’t have one? Like many issues concerning brake

Tech Tip: Maintaining Fluids in Import Vehicles
Picking the proper lubricant for your customers’ import car will depend on the application. For example, serious track racers with large ponies under the hood will want heavy-duty, high-performance racing lubricants designed specifically to stand up under the stress. For the average high-performance import car, quality products will provide good functionality and durability for almost any application.
