1. Open back of the washing machine and control panel. Locate two wire harness coming out of main motor and main board. Check the wires for any cuts and harnesses for any corrosion. Fix the cuts and sand the corrosion to fix the issue.
2. Check the windings on the motor by pulling 3-wire connector from main board. Check resistance between each of 3 pairs using multi meter. The resistance should be 8-15 ohms. If one or more pair has no resistance reading then the winding is burned. Replace the rotor winding.

3. If windings are fine then the hall sensor or speed sensor or motor sensor or sensor assembly needs to be replaced. The hall sensor sits on the inside of the rotor winding. Hall sensor has 4 wire connector attached. To remove the hall sensor: Open the outrunner or magnetic rotor from the motor first. Remove a big bolt at the center of the motor by holding the magnetic rotor. Once bolt is removed, the magnetic rotor can be removed by simply pulling it straight out. You may have to wiggle it a bit. Now remove a screw holding a wire going to hall sensor towrds bottom left of the winding. Now remove six inside bolts holding rotor windings to the drum body. The rotor windings are heavy so be careful while removing the bolts. Remove two wire connectors from the rotor windings and pull out the windings. Lay the rotor windings flat facing connector side up. Remove the hall sensor by praying out tabs.

One of 2 things may be causing the loud noise. Either the rear bearing on the drum has failed and will need to be replaced (very expensive) or the drain pump has a bearing problem and is making a very loud noise when it is draining (not too expensive). Either way, you will need a qualified LG technician to diagnose and repair the problem.
SOURCE: replace bearing
You can try a puller but typically it is recommended to replace the entire rear outer tub half (which comes with the bearings already pressed into it). You will also need the tub seal that goes between the front and rear tub halves. Hope this helps.

firstly u have to take the wire off it with a screwdriver unscrew it take it off then watch how the old on pulls off as there is a lip all around this rubber and it as to bed into the metal drum just see how the old one comes off once you have put the new one on put the wire back around it or it could be a metal strat wich tightens up with a screwdriver,rgds,paul
