Chris R Bellingham , WA November 29, 2018 Appliance: LG Washer WM4270HVA Lg Washer Wm4270hva / 00: Excessive vibration in rinse cycle/machine walking across floor. How to replace Hinge Pin. Ordered damper assembly (3), watched Youtube video and replaced all 3 dampers and pins. Very easy to do after following instructions. Once the front panel of machine was removed I saw the lower weight balance (Lead filled plastic mold around bottom of drum) was off the pins and was just laying loose at bottom of machine. That was why the machine was walking across the floor, but what caused the weight balance to vibrate off over time was the failure of the dampers, causing excessive vibration. Put the weight balance back in place, tightened the bolts that expand the grips that hold on to the pins and now the machine is like brand new. No vibration at all and much quieter. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
