A couple weeks after changing the tailshaft slip yoke seal it would squeal and gets louder as I go faster. I tried greasing the slip yoke shaft and seal and it helped stopped the noise but as the grease flings off the noise returns.

The seal I used has an oil seal and a boot seal:

Any way to get the noise to stop? Old one didn't because it was dripping ATF lol.

Pull the shaft and clean the yoke up with 1200 wet and dry. You can wrap a piece around the yoke and use a piece of rope wrapped once around the paper to spin it back and forth.
Grease the inside of the seal with a teflon grease like super lube.
