Bearings rarely fail in LG washers.
A strong possibility would be a failing Hall Effect Sensor. If the washer *growls* during spin this is usually the Hall Sensor.
If a *clicking* sound is occurring--this may be debris in the tub scraping against the spin basket. This usually requires a major tear-down of the tub assembly to gain access into the tub. Although this is fairly rare---it is usually a bra-wire or a nail.
NOTE:
A *faint* clicking sound when the tub is turned by hand (slowly) is NORMAL.
