David D Allentown , PA April 08, 2017 Appliance: LG Washer WM2016CW Lg Washer Wm2016cw / Abweeus: Noisy banging during spin cycle. How to replace Spider Arm Assembly. Replaced spider arm, and both bearings. Bearings were probably OK, but as long as I had the thing opened up, I thought worth replacing. The video was extremely helpful and well detailed. Removing/reattaching the pistons was a bit tricky, and removing the bolts on the old spider was really tough. Definitely needed penetrating oil and heat, plus a breaker bar. This repair not for the meek. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
