My GE Profile washing machine started squeaking and after isolating the noise to the tub seal, I ordered a seal. The old seal was compromised so it was rusted and swelling rubbing against the bottom of the tub causing the noise. Even though this seal was in pretty bad shape, I never saw any leaking. I replaced the seal and the noise went away and all was well except for a grumbling bearing in the shaft/mode shifter. Within a week, the tub seal was leaking again. I decided there must have been some damage to the shaft at the seal, so a ordered another seal and the shaft/mode shifter. I replaced these without any difficulty and the washer was quiet and ran perfect. Now one week later the new seal is leaking again. The seal fits over the shaft fine and into place without obvious issues. What is going on here? Is is some type of compression that is supposed to be against the seal to help?

Not sure what the air bell bolt and hub nut are. Do you mean tub nut? The first time I only remove the basket to get to the seal. It leaked within a week. I assumed rust or debris may have scored the shaft and since the bearings were getting loud, I then went ahead and replace the shaft and mode shifter along with a new seal. The mode shifter had a torque spec to mount to the platform but that is all I remember. Looking at the leak from below, it is dripping right from the seal area at about a drip every 1-2 seconds with the tub full.

I could see one bad seal but I am now through 2. I notice the ID slips around the shaft securely but not tight. The seal base slides and fits into the area in the tub base easily but not tight. Is there supposed to be anything pressing on the seal to help it compress?

Before I forget, thanks for your assistance, I appreciate it.
I do have an extra tub seal since I did not know the Shaft/Mode Shifter already came with one. I think I will change out the tub seal again and hope for the best. I will take a closer look at the tub to see if I can see any cracks or other defect. After both previous changes the seal did not leak for around a week that may rule out any cracks in the tub.

OK, UPDATE, I took the tub out again and when I removed the seal, the seal spring was on the shaft and not on the seal. I am not sure if it came off when I installed it or whether it came off when I removed it. I decided to re-install the same seal since it looked good. I did add a small layer of silicone seal around the outside perimeter of the seal as a extra precaution. After two weeks and maybe 10 loads, it has not leaked again. (fingers crossed). The bearings are a little noisier but not nearly as loud as before a replaced the shaft and mode shifter. Hopefully this will last. Amazing that just a short time with water will ruin the bearings.
