Joseph S Upper Nyack , NY December 24, 2015 Appliance: LG Washer WM2016CW Lg Washer Wm2016cw / Abweeus: A wobbling washer drum that was chafing the plastic tank causing excessive vibration noise smoke at times and generating plastic shavings in the drum and clothing. How to replace Spider Arm Assembly. This job involves a complete disassembly of the machine. I used a U-Tube video to help with the process and I do have fairly good mechanical skills.The problem was first diagnosed as a worn bearing which I purchased prior to disassembling the machine. As it turned out the bearings were fine and the problem was a badly corroded and cracked Spider Bracket. The level of corrosion surprised me since the machine is only 5 years old but was probably caused by a combination of the poor quality of our local public water supply and the fact that the aluminum spider was mounted to a stainless steel drum and may have created a galvanic reaction. I wound up replacing the bearings and the spider and the machine is now working fine. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
