I posted a fix last week on noisy Kenmore HE3T front loader made by Whirlpool. The brace was out of position and wasn't against the pad on the wall. That was fixed and a brace was added but fell out during first laundry making the machine ultra noisy. The braces in question are on top of pads on the 2 sides of the machine. Still was getting some vibration so technician decided to order another brace for other side, 2 springs and 4 shocks.
Went to replace springs and physically he could not even with my help. Gave up on that. Went to replace 4 shocks at bottom of machine. 2 are replacable from front and 2 others require removal of back panel. Discovered factory had installed one shock upside down compared to 3 others. Not sure if that would be a factor but replaced all 4 and mounted them all in same direction. Ran machine and vibration seemed to be improved. Won't be sure until it is full of laundry. All removed shocks seemed to be ok so if that fixed it then the problem was the upside down shock. Removed added brace so final fix was all new shocks pointed in same direction (but old seem ok) and getting brace under pad correctly.
