Most durable top load washer, suspension systems
The belt drive whirlpool washers had the best suspension of any popular top loading automatic.
The standard capacity models never walked or generally had unbalance problems.
Whirlpool did have some vibration problems with their super capacity washers in the 70s. It’s one of the reasons they reduce the capacity in 1982 somewhat.
Nothing ever went wrong with the suspension and a belt drive whirlpool washer, other than possibly a worn snubber which took absolutely no tools to replace in about 30 seconds to lift the top and flip a new pad in place.
Whirlpool never used an unbalanced switch in their belt drive machines Sears used an unbalanced switch in their fancier models 1/3 to 1/2 of their models did not have one, this was a feature that the salesman could try to upsell people with trying to convince them that they needed this useless gadget on the machine. Over the course of my career, I muster disconnected 300 to 500 on balance switches on Kenmore machines because people are annoyed that machine would cut off.
Maytag never had a very good suspension and had to use an on balance switch to control the machine vibration. This was compounded because of the spin drain of course and also the narrow cabinet width. When Maytag came out with the helical Drive washer. It had a very weak spring system and the damper was aluminum and cork material inside. They beefed it up about 1960 a little bit but it wasn’t until the 06 models in 1966 that it got to work performed a lot better,
