Two new job aids are now available: Packing List for Wildland Fire Fireline Personnel, J-101 and Packing List for Wildland Fire Support Personnel, J-102, should serve as a baseline for items needed on a wildland fire assignment. These lists will help personnel prepare for a 14 to 21-day assignment on the fireline or in a support role.

The average cost to replace the wheel bearings (for 1 wheel) is about $350 (including parts and labor). But KBB.com goes deeper than that.

Simply stated, wheel bearings allow cars and trucks to run smoother and more efficiently by reducing friction and supporting vehicle weight. When they start to fail, you can usually tell.

Step 1. State the primary direction. In this case, the primary direction is south. Step 2. Count the degrees from the primary direction. Counting from south, the angle is 30.° Step 3. State the direction the angle is deflected. The angle is deflected to the East.  Jake's bearing is written as South30°East (S 30°E).

This Safety Warning is intended to highlight the details and recommended procedures for the installation of a Stihl chainsaw toolless fuel cap, as well as how to identify and correct a misaligned, damaged, or broken fuel cap to help prevent fuel spillage.

Compass bearing

Friction from a failing wheel bearing produces heat. After driving, without touching the tires or wheels, carefully walk around your vehicle and use a non-touch thermometer to measure if one is hotter than the others.

You can service or replace tapered wheel bearings yourself. Never reuse any wheel bearing that’s loose, worn, noisy or shows any signs of wear.

The average cost to replace a sealed wheel hub bearing is $350 per wheel. However, depending on the make and model, shop labor rate, the cost of the bearing itself and any additional damage, the total could exceed $1,000.

Read on to learn the most common bad wheel bearing symptoms, based on my experience (50 years in the industry) and that of Joe Simes, a National Institute for Automotive Service Excellence (ASE) certified and Toyota master technician. But first, a little background.

A bad wheel bearing can cause a tire/wheel to move or glide unevenly or sluggishly. It can also cause your brakes to drag, pulling your vehicle to one side when you try to stop.

The cage and rollers are held together inside a hardened metal ring called a “race.” The seal keeps grease in and damaging water and debris out. Wheel bearings are installed inside, and secured to, the suspension, either by press fit, bolts or a snap-ring. Once mounted, the wheel bearing rides on the axle shaft, allowing the tire/wheel to spin effortlessly.

Unlike unbalanced tires, shaking caused by a bad wheel bearing should be obvious from the side of the car where the bearing is failing.

Depending on the vehicle, you can save hundreds in labor replacing wheel bearings yourself. Most auto parts stores will lend you the specialty tools and equipment needed to replace a wheel bearing.

Megan's bearing is written as North70°East (N 70°E). Note that a straight line has two bearings. For example, the line above can be extended down into the SW quadrant. Example 2 - Jake is walking on the line in the sketch going southerly. What is his bearing?

Oct 21, 2017 — $100 for each bearing and $100 for each bearing installation. $400 total plus the cost of an alignment which ranges from $60 to $100. So figure $500.

But sealed wheel bearings are non-serviceable and should never be repaired, only replaced. Even if a pro suggests repairing a bearing, don’t let them. Trying to reuse a damaged wheel bearing can result in an accident and severe injury.

NOTE: Whether you DIY or your mechanic replaces the bearing, always install a new axle hub nut. Most hub nuts are prevailing torque fasteners, used on critical components (like securing axle shafts to hub bearings) where a loose nut could lead to disastrous consequences.

You’ll hear clicking, cracking, grinding, snapping, or whining noises coming from your wheels or tires. They’ll increase when accelerating or turning.

On many vehicles, the ABS sensor is built into the wheel bearing, or it’s externally mounted adjacent to the spinning part of the bearing where the sensor measures vehicle speed. Damaged from a wobbly wheel bearing, the sensor will send erratic readings to the vehicle’s computer, illuminating the ABS light.

Find the angle in degrees that describes the compass bearing

On modern front- and four-wheel drive cars, wheel bearings are a set of permanently sealed, precisely machined steel ball or straight roller bearings. The balls, or rollers, are encased in a “cage” that supports the bearings, allowing them to rotate freely.

Absolutely not. It’s crucial to get bad wheel bearings diagnosed and replaced ASAP. If not, you could lose a wheel or get in an accident.

The Equipment Technology Committee (ETC) has released Safety Warning: 24-001 Stihl Chainsaw Toolless Fuel Cap Spill Prevention. Misaligned toolless fuel caps on Stihl chainsaws have led to recurring fuel spillage, fuel ignition, and burn injuries during wildland fire management operations.

According to Simes, a failing wheel bearing will likely produce a soft, faint vibration that’s felt before it’s heard. There may also be a vague rhythmic humming or droning sound that increases over time and with speed.

A bearing provides a direction given as the primary compass direction (north or south), degree of angle, and an east or west designation. A bearing describes a line as heading north or south, and deflected some number of degrees toward the east or west. A bearing, therefore, will always have an angle less than 90°. Example 1 - Megan starts at a point and goes in the direction shown in the figure below. What is her bearing? Megan is in the NE quadrant. The primary compass direction is north. Count the degrees down from North, for a total of 70°.

The NWCG Standards for Water Scooping Operations, PMS 518 establishes the standards for dispatching, utilizing, and coordinating water scooping aircraft on interagency wildland fires. These standards should be used in conjunction with the NWCG Standards for Aerial Supervision (SAS), PMS 505, and any local, state, or geographic/regional water scooping plans.
