My lg 2301 makes a loud noise when spinning can I grease the bearings believe that's what it is..

SOURCE: Lg WM1812cw makes alot of noise when in spin cycles.

There are always bearings. This model uses a direct drive brushless DC motor so there are no belts and such. Without actually hearing the noise with no load, it's hard to say what may actually be wrong. Any time a motor makes an abnormal noise, you can expect it won't last too much longer. I have the same model so now I'm worried.

How old is your washer.

Unfortunately the first techs post is right on target.
Here is an article I just read that may help you make a decision.

Repair or replace?

When to pull the plug on your old refrigerator

It nearly always makes sense to undertake simple do-it-yourself repairs,
such as replacing a gasket on a refrigerator or a freezer.

Typically, you'll also find a troubleshooting section for more-serious problems
in the owner's manual.

Should you pay for a repair or buy a new model?
The answer depends mostly on the age of your refrigerator,
how much you bought it for,and the cost of the repair.

Follow these guidelines:

When a repair makes sense.

If your refrigerator is under warranty or less than four years old (three years for top-freezers),
paying for a repair makes sense.
Note that refrigerators under warranty might require service from a factory-authorized technician;
readers have found them on a par with independent repairers.

When a repair might be a wise choice.

If your refrigerator is out of warranty and is four to seven years old,
it might make sense to pay for a repair. Customers generally pay $100 to $200 for a repair.
But you might want to buy a new model even at this stage,
given that today's models are quieter and have added features.
Higher energy efficiency is another plus: Energy Star-qualified models made after April 28, 2008,
are 43 percent more efficient than conventional models built before 2001 and 56 percent
more efficient than those built before 1993.

When it pays to replace.

The repair costs more than half the price of a comparable new refrigerator.
Data also shows that it doesn't pay to fix a less-expensive top-freezer refrigerator
six or more years old or a bottom-freezer or side-by-side eight or more years old.

Thanks to better recycling programs, less than 10 percent
of a refrigerator you replace is likely to end up in a landfill.


Thanks for giving me the opportunity to advise you.
Please do not forget to leave a rating.!
Thank You, Huuum

SOURCE: noisey during spin

yes you are right noise during spin cycle is due to faulty bearing. If the tub seal lets go water will weep into the tub bearing. This will rust the basket shaft and normally wreck the tub bearing. Once the bearings starts to get worn enough it usually gets very noisy. The tub bearing is pressed onto the outer back half of the tub shell assembly. Normally need to replace the inner basket/shaft assembly  and the outer shell with the tub bearing. 
Sometimes the inner basket support will crack, this can give an clicking or banging noise as well.
 
Pictures of this job...
A sure indication was the brown junk/gookus leaking out if the rear bearing area and the belt has spewed it around in the drum that the rear bearing and seal was bad...
Picture1 - Picture2
The whole outer shell and basket come out to do this repair....what bad bearing and rusted shaft looked like...
Picture1 - Picture2 - Picture3
I had to remove the back panel. Undo the pump hose & water level hose, remove the 2 shocks, remove the motor, undo the front boot from the outer panel and remove the 2 springs to lift the whole assembly out from the back to work on it.

It leaks Your washer can develop several types of leaks. You can track down a leak based on when it occurs: 

During fill only
During drain and spin only
All the time
During fill only If the washer leaks only during the fill cycle, check these:

• Air-gap device -The air gap is a small device found on most washers that prevents the wash water from being siphoned into the household water supply. It's located either mid-way along or at the end of the black rubber hose that comes from the water-inlet valve. Often it's made of translucent plastic. If one of the air-gap components deforms or cracks, you may need to replace it.



• The tube -There's a rubber tube that runs between the water-inlet valve and either the air-gap or the inlet spout. If it cracks or breaks, it can cause a leak.



• Inlet spout -Most washers have a plastic spout near the top of the main clothes tub that directs the water into the tub. If the spout cracks or breaks free of its mounting, it can cause a leak.

• Hot and cold water fill hoses - Check the hot and cold water hoses from the household plumbing. If either hose is leaking, tighten it or replace it, as appropriate.



• Main tub seal - The main tub seal is located between the transmission and the outer tub. It's the primary water seal in the outer tub for the transmission-shaft entry point. If this seal leaks, you can see the leak by opening up the machine's main access panel while the machine is full of water with a small amount of detergent in it. The leak appears at the underside of the outer tub, at or near the center. This seal is difficult to replace. You probably should call a qualified appliance repair technician.



• Pump - If the pump leaks, you can probably spot the leak when the tub is full of water. The pump has two or more black rubber or plastic hoses attached to it and usually has a drive belt that spins the pump. If the pump is leaking, you need to replace it.



• Outer tub - Over time, the steel or plastic outer tubs can rust, split, or be punctured. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details.

You will need to remove the back cover plate of the machine and locate the large pulley at the end of the drum. Remove the belt, then the pulley and you should see a bearing housing. Some models require a bearing and housing replacement, while others can simply be repaired with a bearing replacement alone.
Go here, and find the nearest Dealer for your part.

Or you can try ordering direct from LG. If you are as handy with tools as you say, this should be a fairly easy job.
