The most accurate measurement will come straight from your motor manufacturer. If there are no specifications available, pump the grease slowly and carefully until clean grease comes out of the discharge port. Do not pump too fast, or grease may be forced through the bearing seals and into the motor cavity.

A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle. If your wheel bearings are worn, it can cause a grinding noise while turning the vehicle. Poor steering and handling and uneven tire wear are just some of the effects of failing wheel bearings.

These bearings are good for high-contamination applications. Sealed bearings are generally only used for lower speed motors, 75 hp and under, and have an anticipated life span of only three years. These types of bearings fall under the “Lubricated for Life” designation and do not require regreasing.

Proper bearing lubrication is key to keeping your motor running correctly. Lubrication separates rolling surfaces to reduce wear, removes excess heat generated by friction, acts as a barrier to contaminants, provides corrosion inhibition, and helps retain rolling elements during assembly.  More than 50% of all bearing failure is due to improper lubrication! If that’s not a good reason to pay attention to the rest of this article, I don’t know what is.

Alternator Grinding noises can also be a sign that the alternator is wearing out. Modern alternators have a decoupler pulley system that helps save fuel but can make a grinding noise that is hard to find. Designed to charge your car’s battery and power the electrical system, a failing alternator can leave you on the side of the road with a dead battery.

To determine if a wheel bearing is the culprit, begin driving your vehicle and make a turn to the right and then complete a turn to the left. If the grinding noise is louder when turning in one direction, the likely cause is a failing wheel bearing. If you suspect you have a bad wheel bearing, get your vehicle to your technician for a diagnosis.

Water Pump A failing water pump can cause a grinding noise while the engine is running. Without a fully functioning water pump, your car can overheat. If you suspect that your water pump is failing, schedule an appointment with your mechanic before further damage is done to your vehicle.

CV Joint A worn CV (constant velocity) joint can cause your vehicle to make grinding noises when making tight turns at slow speeds. Left unattended, a damaged CV joint can fail, leaving you with a vehicle that is stuck in park. If it fails while you’re driving, it can lead to a loss of control. Don’t waste any time in getting your vehicle in to your mechanic if you think this is the cause of your grinding noises.

Greasing electric motors while running

From the roar of the engine to the sound of the brakes, you’re intimately familiar with the regular sounds of your vehicle. When there is a new and unfamiliar noise, it grabs your attention. If the sound persists for a few days, it’s time to get serious about finding the cause, especially if it’s a grinding noise.

Brakes Grinding noises can appear when the brake friction material or brake linings have worn away and the steel brake rotor is rubbing against the metal brake pad backing. This causes metal-to-metal contact when the brakes are applied, creating a grinding noise. Typically, the grinding noise will come from either the front or rear brakes, but generally not both. The repair may include new brake pads and rotors.

Air Conditioning AC compressors can also be a source of a grinding noise, and you may only notice it when your air conditioning system is on. Be sure to get it fixed since it not only keeps you cool in hot weather, but it also helps remove moisture from your windows in the winter.

(Filling the bearing with grease should be one of the last operations completed when mounting a replacement bearing to ensure cleanliness and minimum contamination.)

Motorgreasing schedule

If you’re not up for all that math, some technicians like to make their own schedule based on their knowledge of the motor. Looking at motor failure records, maintenance records, vibration records, and using a bearing tester can help you come up with your own schedule that best fits your needs.

For a typical bearing system the best way to determine when, how much, and which type of grease to use is to go by your motor manufacturer recommendations.

Grinding noises are associated with rotating parts and rotating systems; any part or system that rotates can cause grinding. If your car starts making grinding noises, don’t wait to get it checked out -- have your technician take care of it before it turns into a bigger issue.

If the wheel/hub bearings aren’t causing the grinding noises, it’s time to explore other parts that could be the source of your issues:

Motor bearing greasetype

These types of bearings help to retain grease and prevent large particles and contaminants from entering bearing cavities. Single shielded bearings do need to be regreased per the manufacturer’s directions; but double shielded bearings are typically the “Lubricated for Life” design and usually do not require regreasing.

All greases currently on the market are composed of a base oil (mineral or synthetic), a thickener (polyurea, lithium, etc.), and other additives (anti-oxidants, rust inhibitors, anti-foaming additives, etc.) This complex mixture of different chemicals causes all grease to deteriorate at some rate, even under perfect operating conditions. This means that with most bearings, you will need to regrease at some point. The four main causes of grease deterioration are oxidation, oil bleeding, mechanical working, and evaporation.
