Mike I have an LG front loader. It began making a metal grinding noise. After some research I replaced the hall sensor. That did not affect it. The noise I was hearing sounded like a grind. I then replaced the stater and rotor and I still have the same grinding noise. When I remove the rotor I can spin the center spline freely. The bearing has no play or grease and it does spin with out noise. I don't encounter the noise until the rotor is in place. In addition when I install the rotor and I tighten the center bolt it hits on the hall sensor pushing it off of the stater. I don't understand how the rotor can even touch the hall sensor. Even with the new replacements this still rings true. Any suggestions.
Answer Mike, Based on the information provided, you will want to pull the inner tub and check the spider/spindle on the tub for broken welds and check outer tub bearings for wear. It sounds like the inner tub is flexing causing the rotor and stator to wobble. Read More... Answered by AppliancePartsPros.com | Wednesday, February 20, 2013
