The upper counter-balance weight mount design is a poor design to begin with. It started to rattle loose approximately 5yrs into the 8yrs that we've owned it. As it would start to loosen up (as evidenced by the loud banging noise exhibited during operation); I'd shut it down, pull the top off, remove the weight (it was almost always half rattled off at this point), wrap the mount lugs with friction tape (the plastic lugs were being worn down/chaffed by the balance weight), put the weight back on and run the screws into the expanding lugs to secure it. After about a year of these repairs I had to get bigger screws to expand the lugs fully. I had been milking it along over the last three years by this method until it finally just broke off the mount lugs and tore though the tub gasket (boot). Repair is actually not too bad as long as you have the expander pliers to remove the inner and outer door gasket clamps. It's all pretty self-explanatory for anyone with even a little mechanical aptitude. The hardest part is getting the tub springs on and off, helps to have a second set of hands to support the tub (hold the tub up) while the springs are removed/installed. Other than that it's a fairly straight forward procedure. I replaced the outer portion of the tub and the tub gasket. To be fair to LG we really like the unit and we wash a ton of clothes in this thing (household of 9), overall it's been a great - like anything it has had its share of issues, mostly R & R of a part this issue was the only nagging problem that I've had to deal with (well, the tub drain pump motors are a pain but that's another story for another time). Thanks to Appliance Parts Pros for having the parts in stock and shipping them so quickly. Without you all, I'd be buying another $2600 unit!
