Once you understand load share, it’s clear why Acme Corrugated Box needs to know a future box’s entire story in order to design for optimal performance. After load share and other essential elements have been discussed from all angles, the design team can recommend box characteristics including a board grade. The sturdiest board grades are used in scenarios where a box’s contents will offer low or no load share.

At the bottom end of the load share spectrum are boxes containing breakable contents or contents that compress under pressure, like towels, sponges, or tortilla chips. In these scenarios, the box itself needs to provide all of the crush resistance to protect both the box and its contents from the effects of weight.

High load share is achieved when a box’s contents are sturdy enough and packed tightly enough to enhance a box’s stacking strength beyond the box’s standard crush resistance rating. A box packed tightly with books, for example, has near-infinite load share.

“When contents aren’t contributing to load share as needed, Acme Corrugated Box often turns to its proprietary grades, such as BD, ED, Powerwall 100 and Powerwall 60,” Bittner says. “These offer greater crush resistance than what most other box manufacturers can provide. Our designers can also work with customers to minimize complicating factors like head space and air channels.” Interior packaging elements such as pads and dividers can also be used to increase a box’s crush resistance.

“Boxes might seem like a commodity, but they’re not, and load share often helps our customers understand why. Customization is key to optimal box performance as well as optimal business outcomes.”

“Box design is more complex and critical than many people realize,” explains Jeff Bittner, Business Development Manager at Acme Corrugated Box. “It’s why our design team does a deep dive with customers before they design any made-to-order corrugated product. From transit to storage conditions to warehouse practices to end use, there are many factors to consider, and many of these factors brush up against the topic of load share.”

Your location can also be a key factor in determining the price of a wheel bearing replacement. For example, average hourly labour rates and demand in cities like London is around £50-£100 while in towns with lower demand, the labour rates can range from £35-£50. The type of mechanic, for example, a mobile mechanic vs a dealership garage technician can also affect the total cost of a wheel bearing replacement.

Wheel bearings are important components of a car's suspension system. They allow the wheels to rotate smoothly and with little friction. Wheel bearings typically last around 80,000 miles, but they can start to wear down sooner if the car is driven in harsh conditions or if the suspension is not maintained and serviced as needed.

To avoid having car owners overpaying and get a fair price for a wheel bearing replacement, we use real-time data of thousands of car makes and model data, local labour prices for wheel bearing repairs and replacements and part prices to provide an instant fair quote. Simply enter your vehicle registration number and postcode to get an instant price for a wheel bearing replacement for your car.

Replacing wheel bearings is definitely worth it to extend the life of your tyres and other suspension components. You can replace all 4 bearings or just the one if needed.

A wheel bearing replacement is a complex job that requires automotive repair skills and specialised tools as it involves working with a vehicle's suspension, braking, and steering components.

If a wheel bearing starts to fail, it will make a grinding or growling noise while the vehicle is in motion. This noise will usually get louder as the bearing wears down. In some cases, the noise can be similar to that of brakes grinding. Once a wheel bearing fails, it must be replaced as soon as possible to avoid further damage to the suspension system.

Ultimately, the time that the job will take will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.

More noticeable at low speeds, a broken wheel bearing will cause vibrations which are typically coupled with a grinding sound.

Over time, a damaged wheel bearing can affect your car’s steering, as the weight of the bearings, or any defects in the race can cause your wheels to not sit level with the road. This can lead to uneven and premature tyre wear, and your car behaving unpredictably when turning corners. Once the problem has been diagnosed, a wheel bearing replacement should be carried out as soon as possible. * Mechanic will loosen the lug nuts of the wheel where the bearing has been affected and remove the wheel * Mechanic will remove the brake disc and caliper if needed * Mechanic will remove the hub nut holding the wheel bearings assembly * Mechanic will press out old/ damaged bearing * Area will be inspected, cleaned and new wheel bearing will be installed * Mechanic will reinstall all parts as required

Load share decreases when there’s empty space between the top of contents and the top of the box (known as head space) or if there’s empty space between or around contents (known as air channels).

The average cost of replacing a wheel bearing is £175, with prices ranging from £120 and £300. The cost will vary depending on whether the front or rear or if all of the wheel bearings need replacing. In some cases, if the faulty wheel bearings have caused additional damage to other parts of the suspension or transmission, then the necessary parts will need to be replaced which could affect the overall cost of the repair. The exact price of the wheel bearing replacement depends largely on your car and the parts recommended by the manufacturer.

If you hear a grinding or growling noise coming from the wheels, these are signs that your wheel bearings need to be replaced.

Load sharing is the extent to which a box’s contents contribute to crush resistance, or its ability to stand up to weight placed on top of it. Because box stacking is common practice, designers need to understand a box’s contents (which determine load share) and the box’s end use (which determines the need for load share) before they can start designing it.

If a wheel bearing becomes faulty, it will usually make a grinding noise that will become louder as the vehicle moves faster. The vehicle may also feel like it is shaking, the noise may also vary in pitch as you turn the steering and travel around corners. When you notice any of these symptoms, it’s important to get it inspected as soon as possible as continuing to drive can be dangerous and cause further damage to the vehicle.

It is recommended that you do not drive with a damaged wheel bearing. Continuing to drive is not only extremely dangerous but can also cause extensive damage to the hub, axle and other associated parts.

“Assuming every cubic inch of that box is filled with books, it would take vast amounts of pressure to crush it, because books are practically crush-resistant,” Bittner says. “Theoretically, you could stack these boxes to the sky without crushing the books or the bottom-most boxes. We call this absolute load share. The product is doing all of the work; the box is really just a protective wrapper, freed from the burden of stacking strength.”

“A box packed three-quarters high with books offers limited load share because while the books’ sturdiness could help with the structural integrity of the box, the head space could invite crushing if the boxes are stacked too high or if too much weight is placed on top,” according to Bittner. “Limited load share also occurs in boxes packed unevenly, packed with fragile or breakable contents, or packed with substantial air channels between contents.” Contents prone to bulging or settling during transit (for example, boxes containing bags of ground spices or juice concentrates) also find themselves in this common middle ground.

A front wheel bearing replacement on average takes just over 1 hour, but can take anywhere from under 1 hour to 2 hours. This is because replacing front wheel bearings tends to be a bit more time-consuming than replacing rear wheel bearings as it may require removal and reassembly of additional car parts. A rear wheel bearing replacement takes on average under 1 hour but can range from under 1 hour to 2 hours.

The best practice is to replace all four wheel bearings at the same time or at the very least should be replaced in pairs, ie front or rear. This ensures that all four bearings are the same age and have been through the same amount of wear and tear. Additionally, if one wheel bearing needs to be replaced, the other three are likely to need replacement fairly soon. You can, of course, choose to replace one at a time but it’s not advisable and is often not the most economical choice in the long run.
