Product review (5 stars): My washer is quiet and working again!
Like other reviews I'd read, I wasn't sure the suspension rods would solve my problem with my washer (Whirlpool WTW6400SW1) or not. It was thumping soon after starting a load, then would display "UL" with 11-12 minutes left in the cycle, beep and stop. I nursed it along for quite a while by readjusting the load. Then I had to readjust multiple times, until even that didn't work anymore.

I'd already made sure the machine was level, and the rods appeared to all be intact. I took a leap of faith and ordered the kit.

It completely fixed the problem! No more loud thumping, and the "UL" has only popped up and stopped when the load really was off balance. One readjustment of the dog blankets was all that was needed. I'm guessing the springs on the rods were worn out.

Like some others, having a second person to help hold the drum up while getting the rods off and on was a help. I'm not sure I could've done it by myself. I'm glad I tried this, since I was thinking I might have to buy a new washer.
