Product review (4 stars): Another "must have" on the replacement list...
If you're removing your tub, or doing any kind of transmission work on a machine with, at minimum, a few years of wear and tear, then this is nearly a required part to have on hand for completing the job.

It's not that big a surprise that for a rubber seal that spends its life submerged in left over rinse water, it's an important part of keeping the underside of the washing machine dry. After hundreds of loads of tightly hugging the churning transmission's spindle, little drips of water began making their way down to the transmission housing, then the drive pulley, where the water gets flung all over the machine.

The old seal pulls off really easily, and the new one seats just as easily. The old seal was never giving up more than just a light drip, but especially with a new transmission shaft to seat against, there was no point in completing the job with the old seal.
