ARE YOU USING BULK 55 GALLON DRUMS OF BRAKE CLEANER?
To save on costs, many service departments are purchasing flammable liquids such as brake cleaner, lacquer thinner, gasoline, and other flammable liquids in bulk 55-gallon drums. While this may make economic sense, you may have to spend a bit more upfront to comply with flammable liquid storage regulations.
FEDERAL INSPECTION FINDS EL PASO METAL STAMPING MANUFACTURER WILLFULLY
EXPOSED WORKERS TO AMPUTATION DANGERS; WORKER SUFFERS SEVERE INJURY
An El Paso metal stamping manufacturer with a history of workplace safety violations failed again to protect its workers from the dangers of moving machine parts. As a result, a worker suffered the amputation of two fingers inside a 500-ton hydraulic press.
OSHA INITIATIVE SEEKS TO PROTECT MANUFACTURING WORKERS
IN MIDWEST FACILITIES FROM HAZARDOUS NOISE LEVELS
Nearly one in 10 people endure noise levels at work loud enough to cause hearing loss while seven in 10 experience moderately loud noise levels, reports the Bureau of Labor Statistics. Yet, the bureau's Occupational Requirements Survey, published in 2019, found that more than half of the nation's manufacturing workers reported not using personal protective equipment to protect their hearing.
TACKLING CALIBRATIONS IN THE SHOP
Advanced driver assistance systems (ADAS), has quite literally been all the rage for the last several years. So many articles, social media groups, forums, training classes, and podcast episodes have become dedicated to the subject. But why? For starters, in a profession where technology is always evolving, this was a big change from normal service. ADAS is not really all that new, arguably debuting back in 1999 with Mercedes-Benz “Distronic,” which used radar for adaptive cruise control (ACC). But now we are seeing it on virtually every high-line vehicle, and it's absolutely trickling down to the more economical models.
MACK TRUCK RECALL
Mack Trucks is recalling certain 2018-2022 Anthem, Granite, and Pinnacle vehicles equipped with "camelback" rear suspension and electronic stability control. The vehicles may not stay in their lane at certain speeds. As such, these Stability Control Systems on Heavy Vehicles." A vehicle that drifts out of its lane increases the risk of a crash. NHTSA says potentially 566 vehicles are affected by this recall.
For the most part, the typical vehicle in our shops are not 2018 and up. But this is an indication that the world of
being aware of sensors and wiring, albeit on suspensions, is near. Please advise on newer vehicles to be aware of wiring that typically has not been present ever on suspensions.
TROUBLESHOOTING BRAKE IMBALANCE IN CLASS 8 TRUCKS
What is brake balance? A vehicle’s brakes are said to be in balance if all brakes apply and release at about the same time, with each brake developing the appropriate braking force for its weight load.
On the other hand, brake imbalance, such as when a tractor brakes faster and more aggressively than its trailer, causes rapid lining wear on the hardest-working brakes, bumping of tractors by trailers, jackknifing and panic stops with more panic than stop.
AUTOMATIC SLACK ADJUSTERS

4 WAYS TO PREVENT TRUCK WHEEL-OFFS
The causes of wheel separation are well known. They include bearing failures; loose, broken, or missing wheel fasteners; damaged wheels, and to a lesser degree, failures of certain axle and suspension components. What's not as well understood is why these events continue to occur.
TIGHT BUT NOT TOO TIGHT WHEEL BEARING ADJUSTMENTS
Bearing failures are less common than fastener-related separations, 26%compared to 65%,say several investigative reports on wheel separations.
HOW TO PREVENT WHEEL-END FIRES
Millions of dollars’ worth of equipment and cargo goes up in smoke every year because of wheel-end fires, euphemistically called thermal events. You’ll see it on the news or social media, with dramatic footage of thick black smoke and flames consuming an entire trailer — and the tractor, if the driver can’t get the two units unhooked fast enough.
But determining how and where the fires start continues to frustrate the maintenance community, because the damage is often so severe, there’s little left pointing to a cause.
