Oxygen Sensors: Are You Up to Date on the Latest Designs?
If you’re a technician who works on late-model import vehicles and diagnoses engine performance and emissions problems, you probably have a good understanding of how oxygen (O2) sensors work. You know that all late-model engines have at least one or more “upstream” O2 sensors in the exhaust system to monitor the air/fuel mixture, and one
Getting a Fix on Piston Diagnosis and Inspection
Piston failures in late-model engines are relatively uncommon thanks to computerized engine controls that keep a close watch on the air/fuel mixture, and knock sensors that back off spark timing advance if detonation is detected. Pistons are also lasting longer because many engines now come factory-equipped with stronger hypereutectic alloy pistons that can withstand higher
Tech Tip: The Great Oil Debate
Are oil changes every 3,000 miles really necessary? It depends on how a vehicle is driven. Some newer cars and SUVs have sophisticated "oil monitors" that estimate oil life based on miles driven, idle time, engine rpm, load and operating temperature. Using these inputs, the computer turns on a service reminder light when it estimates the oil needs to ….
Vehicle Lift Certification: What Is It, and Why Does It Matter?
State and local building codes in every U.S. state, plus Washington, D.C., now require that all installed vehicle lifts be certified to meet ANSI/ALI ALCTV-2006 safety standards. This requirement is found in the International Building Code (IBC Chapter 30, Section 3001.2), as adopted at the local and/or state level. So what is ANSI/ALI ALCTV-2006? It is the recognized American National Standard governing the design, construction, testing and validation of automotive lifts ….
Tech Tip: Vehicle Safety Hinges on Understanding, Checking and Replacing Ball Joints
If the engine quits at 60 mph, you have a chance of getting off the road safely. If a ball joint quits, you have a chance of crashing off the road. The ball joint is one moveable part of a control arm assembly. The control arm bushings are just as important as the ball joint – if the ball joint is worn, chances are the bushings are just as worn. In the case of a strut suspension, the upper mount can receive as much wear as ….

Rack & Pinion VS. Recirculating Ball
Most steering systems you will see in your bays are sealed. But, this does not mean that they do not need to be diagnosed, serviced or replaced. The most important thing to effectively accomplish this is to understand what is going on inside the steering box or rack. You may think the diagnosis of a
Tech Feature: Worn Steering and Suspension Parts are Often Overlooked
It’s a little known fact that many cars and trucks that end up in junkyards have never had any major steering or suspension parts replaced. They still have the original equipment shocks and struts, springs, ball joints, tie rod ends and steering racks. So does this mean junkyards all across America are full of perfectly good parts? Not these parts ….
JGR Does it Again with the Help of SPICER Chassis Technology
Once again, SPICER Chassis helped Joe Gibbs Racing drivers Kyle Busch and Tony Stewart take checkered flags over the past weekend at Darlington Raceway. Busch captured his third NASCAR Sprint Cup victory of the ….
