If your LG washing machine has been shaking, making weird noises, or running erratically, chances are you need new shock absorbers. This 3-pack kit includes everything you need to get your machine running smoothly again - three 4901ER2003A shock absorbers plus six mounting pins for easy installation. These are compatible with a bunch of LG models including WM1812CW, WM2010CW, WM2050CW, WM3431HW and several others. The shock absorbers measure 11.4 inches when extended and 7.5 inches when compressed, so they fit perfectly in the designated spaces. What do they actually do? Well, they cushion and balance the drum during spin cycles, reducing vibration and preventing that awful banging noise that makes you think your machine is about to walk across the floor. If you've been dealing with a noisy washer that shakes your entire laundry room, replacing these can make a huge difference. The installation isn't too complicated if you're somewhat handy - there are plenty of YouTube tutorials showing exactly how to do it. Having three in the pack means you can replace them all at once, which is recommended for even performance. The quality seems solid - they're built to withstand constant movement and moisture inside your machine. Much cheaper than calling a repair person or buying a new washer! Just make sure to unplug your machine before starting the repair, and take your time following the steps. Your clothes and your ears will thank you afterward.
