Removal of the bearings

LOUD NOISES IN MACHINE;

LOT OF THINGS TO CHECK, THE BELT LOOSE OR WORN, THE CLUTCH, THE TRANNY, THE BEARINGS BOTH TUB SEAL AND BEARING, THE REAR DRUM BEARING,
THE DRIVE PULLEY- If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.
THE TRANSMISSION, THE MOTOR COUPLER, THE MOTOR DRIVE BEARINGS,
THE DRIVE MOTOR- If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

how to replace the bearings on an LG WM12230FB washing machine Google...

Hi

In a washing machine, the bearings protect the drive shaft from over rotation due to the forces applied to the washtub.
Unplug the washing machine from the power outlet. Turn off and disconnect the washer from the water pipes. Pull the machine forward so that you have easy access to the entire machine.

Unscrew the lid's top two screws and remove the machine's top panel.

Slide out the machine's back panel.

Slide off the fan belt and set it aside.

Unscrew the drive shaft's end bolt. This is the bolt that holds the pulley into position.

Remove the pulley by placing the screwdriver underneath it and gently leveraging it off.

Remove the drum's three bolts that hold its spider bracket into place. If the bolts are sticking use, rust remover and degreaser to loosen them. Do not apply too much pressure to the brackets or you will strip them.

Tap the spider joint gently with a hammer while pulling on it. The entire joint and the bearings should slide off.

Clean up the spider shaft, removing all rust and debris using cloth diapers and rust remover and degreaser solutions.

Tap the new bearings into place.

Tap the new drive shaft seal into place. The drive shaft seal should always be replaced with the bearings to ensure water-tight protection for the machinery.

Reassemble to washer.

Have you remove the tub nut from the shaft?

you will need to remove the pulley first, the screw in the middle will need a knock to release the loctite.
you will then need to remove the spider assembly, that's the metal cross the bearings are sitting in. there are bolts set around the drum. spray the bearings shaft with oil to help removal, and you may need to hammer the spider as you remove it to loosen it. be careful of the heater.
then knock the bearings and seal out and do the reverse proceedure to put back together.

generally when a machine gets noisy in spin cycle it is due to bearings being worn open the door with the machine empty and try lifting the the drum upwards if it moves then it will be the bearings

if its a direct drive remove the rotor and see if theres a loose magnet etc,hope this helps

drum bearings, check and investigate, remove drive belt and then rotate, if still noisy then yes its the drum bearings, if the noise stops when the belt removed the motor bearings are faulty costly repair on most models, sorry oh there is also the possibility there is something lodged within the drum cavity between the lining and the drum casing

most lg front loaders have the plastic outer drums which have about 16 h/duty screws holding the two halves together. extreemly tricky to strip to gain access to inner bearing and seal. Th/stat, motor, piping and other items have to be removed and dissassembled to enable drum to be removed. that repair i suggest for a service repair.

If you're talking about the rear drum support bearing, they are usually not removable. They are molded into the plastic tub shell. When the bearings go bad you generally have to replace the entire back shell of the wash tub.
