Product review (5 stars): FIXED THE UNEVEN LOAD AND BANGING SITUATION!
My Whirlpool Cabrio washing machine had developed a persistent issue a few months ago with the inner drum going off balance and maniacally banging around the unit almost every time I did the laundry.  It didn't matter what the size of the load was, or the water level, it would go awry almost every load, even though the contents were perfectly distributed inside the machine.  By the umpteenth time of infernal banging; hours of wasted time to complete a single load; and wasted gallons of water, I was ready to throw the set out and buy something new.

My washing machine is from 2008, model WTW6200SW2, so after looking online for a potential cause, I discovered it was likely the suspension rods. The rods came factory boxed and labeled as a genuine Whirlpool part, made in the U.S. and technically speaking, it is really easy to do the replacement of this part.  Physically speaking, as a moderately strong female, it was a tricky task, but totally doable solo.  HEADS UP FOR LID ISSUE: The lid on my washer refused to allow the spring clips to release one at a time.  If one spring clip fully disengaged and the lid corner was even moderately lifted, it was IMPOSSIBLE to press in the other clip.  To finally be able to release the lid, I had to press in one spring clip and lift that side "just enough" to separate it, but not disengage from the clip, and hold the lid it in that extremely awkward position while I disengaged the other clip.

I live in a condo, so my washer is in a closet, and although I was able to replace both front rods without pulling the washer out more than a few inches for the lid accommodation, I did end up having to pull the washer out of the closet all the way for proper body positioning and easy rear rod access.

TIP: I foolishly did not remove the grease residue off the rod stems, thinking it might be anti rust lube, so I struggled horribly installing the first two rods, because the darn things just kept sliding down before I could latch them onto their mounts.  However, once I cleaned the stems, it was very easy to get a solid grip on them and get the other two in place.  Upon completion,  I did three loads of laundry with varying sizes and water levels, and so far, not a single UL error, or drum banging, so this particular part seems to have completely resolved the problems with my washing machine.

I will mention, the original suspension rods looked perfectly good, without any noticeable deficiencies compared to the new ones; however, they (or the design of something) obviously were kaput, because the new ones seemed to have completely fixed the imbalance issue.  I would definitely recommend trying this part first if you are experiencing a washing machine with symptoms like mine.

UPDATE MAY 12/17:  Have done many loads since the replacement and not a single UL error or banging issue.

UPDATE AUG 31/18:  Confirming the washer is still working perfectly since this repair.
