Packing the bearing is extremely important to expel any water that might have slipped past the seals and into the bearings. If you do this after washing your machine every time, the bearings will last a lifetime.
Step 1: Use a high temperature lithium grease in the grease gun and place the needle in the holes by the bearings.
Step 2: Squeeze 4-5 times to expel all water. You will see some grease come out.
