Besides lubricant costs, half of acquired components require relubrication. Overtime labor is mostly a result of machine failures typically caused by inadequate lubrication. In addition, approximately 5 percent of labor costs can be attributed to lubrication activities.

To illustrate this point, consider that on average, a human being requires about 2,000 calories per day. Would you rather consume your weekly total of 14,000 calories once a week or in nearly equal amounts over seven days?

Cupping may also be a sign that your vehicle has suspension problems. Take your vehicle to an auto repair shop right away once you notice any signs of uneven tire wear.

For example, consider a bearing that needs to be relubricated with 2 grams of grease every week. With a standard grease gun, this would mean that the bearing should receive about 1.3 “strokes.” However, manually delivering 0.3 strokes is difficult. In reality, two strokes would likely be given. In other words, the bearing would receive 3 grams instead of 2 grams of lubricant each time.

Pro Tip: If you’re not sure whether you’re hearing a tire noise or a bearing noise, rotate the tires and see what changes. Some front-wheel drive vehicles will make tire noises if the rear wheels are moved to the front after a lot of miles without being properly rotated.

If your tires seem to be in good condition, you can go ahead and check the condition of your wheel bearings. Check for wheel bearing play by rocking the wheel or tire assembly. But note that sometimes you won’t notice any movement even if the wheel bearing is noisy.

Lubrication is an essential part of machinery maintenance for nearly every production facility. On average, lubricant purchases amount to only 3 percent of a maintenance budget, but lubrication-related activities can influence an estimated 40 percent of total maintenance costs.

As the maturity of maintenance and associated lubrication programs increases, so does the complexity of tasks that lubrication technicians must be capable of completing. These include activities such as:

Once you’re quite sure that the noise is coming from the wheel area, you can raise your vehicle using a jack. Make sure that the vehicle is supported by jack stands for your safety.

Therefore, as more mature maintenance programs are adopted, the areas where skilled maintenance technicians can add value to your operations need to be carefully considered. For example, are they best utilized performing manual relubrication, which can easily be automated, or by using their skills and knowledge to perform more analytical tasks, lubricant analysis and making improvements to the lubrication program?

Spin the tires to check if the bearing is making a noise. But realize that some bearing noises will only be present if the weight of the vehicle is sitting on the bearing, so just spinning the tire might not tell you anything. While you have the tire where you can spin it, carefully inspect it and look at the tread while it’s spinning to see if you notice anything unusual.

Simply using automation doesn’t guarantee success. The technology must be considered an instrument to achieve a goal. Basic decisions and activities must still be performed. The following are typical mistakes that can jeopardize the potential benefits of deploying automatic lubrication.

Does a bad wheel bearing make noisewhen driving

The maturity level of a maintenance program (corrective, preventive, predictive, etc.) will dictate the skill and knowledge level required of personnel involved in lubrication-related activities.

While going to a mechanic is the easiest way to determine which component is making unusual noises, there are some things you can do to help pinpoint which parts may need attention.

A single-point automatic lubrication system can deliver the right amount of grease at the right time to each lubrication point. This reduces both grease waste and the risk of bearing failure.

Remember that the steps mentioned above are initial diagnostic measures you can do to help identify potential causes of the noise. If you don’t have the tools and advanced technical know-how, it’s always best to contact a trusted mechanic. A professional will be able to conduct thorough inspections, use the proper tools, and provide a conclusive diagnosis.

Take note that wheel bearing noise is not always consistent, but may change with speed, during turns, or while applying the brake. Likewise, tire noise can come and go in much the same way.

The lubricant and the automatic lubrication device must complement each other to ensure a better overall performance. Needless to say, not all lubricants are suitable for all automatic lubrication systems, and the impact of a lubrication system on the structure of the lubricant depends on the technology of that given lubrication system.

Pro Tip: The hoses may also be stuck and will need to be peeled loose from the fitting after you make a linear cut.

As a fundamental in any lubrication program, the lubricant selection must precede the lubrication system selection. After all, the lubricant that goes into the application is what lubricates, not the delivery system itself.

Trying to find out what’s causing the strange noises from your vehicle can be like solving a complex puzzle. For example, it can be hard to distinguish wheel bearing noise from tire noise since they can sound alike.

In order to achieve optimum reliability and maximum benefits from a lubrication program, several factors need to be taken into account. These factors are summarized by the well-known five “R”s of lubrication:

The simple task of pushing a lever on a grease gun to provide manual lubrication can be easily replaced by a machine. However, the real issue is whether you are getting the maximum value from your skilled maintenance technicians. Such personnel can manage a lubrication program through:

Wheel bearingreplacement cost

The fourth “R” refers to best practices, such as tagging and color-coding (or other methodology) of both lubrication points and tools in order to avoid cross-contamination.

Wheel bearing and tire noises can be hard to differentiate but there are ways to help you pinpoint the source of the sound. But be warned: some of these noises even befuddle experts.

Of course, deploying an automatic lubrication system requires some level of investment. To maximize the return on that investment, the key is to choose the right solution based on the requirements and criticality of the application. Typical solutions range from inexpensive single-point automatic lubricators to very complex centralized systems with various options for online monitoring. Determining which option is best for your application depends to a great extent on your criticality analysis.

Keep in mind that while deploying automatic lubrication systems can free personnel from time-consuming basic activities to provide extra value, it cannot replace staff who can deliver value at this level.

Improper relubrication activities can have a significant impact on the environment. Consider again the grease waste calculations in the previous example. Now try to estimate the impact of this waste on the environment. Naturally, it depends on the disposal practices you implement at your facilities, but in basic environmental terms, the less waste the better.

In the previous example, the technician will relubricate the given point 52 times a year. As a result, the bearing will be exposed 52 times to external contamination as well as to over- and under-lubrication.

There are many advantages in using automatic lubrication systems. These include reduced waste and risk of bearing failure, cleanliness, less labor, and improved environmental health and safety.

Yes. In some instances, a bad wheel bearing can cause uneven tire wear, resulting in combined noise from both components.

Moreover, lubrication routes must be updated, and manual lubrication tasks must be replaced with inspection tasks at an adequate interval. The frequency of inspection is less than that required for manual relubrication, but it still must be planned.

Check your tires for cupping or sharp edges, which may cause growling or grinding noises while driving. If you spin the tires in the air and see the tread lines making lateral movements, or if the car seems to be waddling back and forth during slow parking lot maneuvers, suspect belt separation in a tire.

SimpleTire lets you shop for tires by vehicle model or the size, brand, or type of tire you want. The more, the merrier—purchase four or more tires to get roadside assistance all day. And to set your mind at ease even further, SimpleTire provides tire replacement coverage for free.

Processes must be clean to ensure no external contamination ingress to the grease, and each lubrication point should have a cap on its grease fitting. In addition, the utmost clean relubrication process for each point must be followed every time.

Relubrication quantities are dictated by the physical space available in the bearing, while relubrication intervals are dictated by the working conditions that determine the degradation rate of the lubricant (speed, load, temperature, type of bearing, etc.).

Have a passenger ride in the rear during a test drive to check where the noise is coming from. You’ll have to confirm if it’s coming from the wheel area or other parts of your vehicle, like the engine. You can also check to see if it is mirrored by engine speed or seems to be road-speed related.

Lubricant contamination will also affect bearing life and increase the risk of failure. In manual lubrication programs, avoiding grease contamination can be a challenge.

This example shows the benefit of accurately delivering the right quantity of lubricant (the second “R”), but what about the frequency of lubrication (the third “R”)?

Next, consider points that are difficult or even hazardous to access and the potential impact to your personnel. This is another area where automatic lubrication systems offer real benefits.

By comparison, a properly installed single-point automatic lubricator can supply a continuous and accurate flow of fresh and clean lubricant, keeping the application in proper condition while at the same time preventing contaminant ingress.

Automatic lubrication alone certainly is not the solution to all your lubrication issues. It must be properly understood to boost its potential benefits. However, there are solutions available in the market for virtually every application, so it is difficult to imagine that a critical application is not worth equipping with an automatic lubrication device.

Frontwheel bearing noisesymptoms

Having an automatic lubrication device doesn’t mean that the system won’t require any inspection. Regular inspection will help ensure the best results from an automated system. Inspection also will help to identify installation issues (damaged fittings, leaking or blocked pipes, lubricators not dispensing at the right pace, etc.) and spot when it’s time to change or refill lubricants.

The fifth “R” can be defined once the application conditions, asset criticality and maintenance strategy are analyzed. This will help you make the decision on whether to automate each lubrication point. In order to make that decision, the pros and cons of automatic lubrication should also be understood and considered.

Extending relubrication intervals beyond the calculated limits will expose the lubricant to excessive degradation and the bearing to lubricant starvation conditions. On the contrary, shortened relubrication intervals with adjusted quantities would renew the lubricant’s properties.

The starting point of an effective lubrication program is the detailed mapping of all lubrication points, including their working conditions, lubrication requirements and criticality. This information is needed to select the most suitable lubricant and the quantity of lubricant needed, as well as to calculate the adequate relubrication intervals. These are the first three “R”s.

Consequently, parameters like pumpability and oil separation must be taken into account when an automatic lubrication system is to be installed. Furthermore, relubrication intervals must be defined in a way that prevents the lubricant from being stationary inside the lubrication ducts, especially when exposed to extreme temperatures that could promote premature degradation. Failure to understand and act on these issues can affect the performance and associated benefits of deploying an automatic lubrication system.

If we assume the technician is satisfied with two strokes (if he doesn’t see any grease coming out of the seals), then after a year the bearing will receive 156 grams (52 weeks times 3 grams per week) instead of 104 grams (52 weeks times 2 grams per week). This means that up to 52 grams (50 percent) of grease will be wasted.

If you spin the tires in the air and see the tread lines making lateral movements, or if the car seems to be waddling back and forth during slow parking lot maneuvers, suspect belt separation in a tire.

To determine which part is causing the noise, turn your steering wheel left and right while driving. If the noise gets louder while turning, faulty wheel bearings are the likely culprit.

Does a bad wheel bearing make noisewhile driving

A squealing or grinding noise that worsens during acceleration is a tell-tale sign that your wheel bearing is bad. If the noise is steady, you’re probably dealing with a tire-related issue. Underinflated or misaligned tires may produce a vaguely similar noise, except that tires won’t squeal unless you’re doing a jackrabbit start or rounding a corner too fast.

A knocking or thumping noise may be caused by a tire wear pattern that happened while the vehicle was driven a long way with the vehicle needing an alignment.
