Even though it looks more like it swelled from soaking in oil (or something else) usually it's from getting hit by something. IME anyway.....
Hydro bumps: you can ride on them at ride height or you can set them to contact at some point into the up travel. Can even set them to make contact somewhere in the droop travel. They do not care. Depending on how they interact with the rest of the suspension there may be some noise from the actual contact.
There is valving in them and you can tune the oil volume as well as the N2 charge pressure to tune how they behave. I would buy at least a 4" stroke and make the mounts to allow you to try different points of contact in the travel. You can also internally limit their down-stroke, which is why I say buy the 4" version at minimum. Can always make or buy or have made some sleaves to fit over the shaft inside of the bump to limit their down-stroke, but if you end up needing a longer stroke you have to start over.
The old school recommendation was that there still be some final travel limiter other than the hydro bumps, but I've been told that some mfg's are now saying that you can use them as the final limiter. Personally I'd have a small urethane pad as the final limit if space allows.

Hey thanks for the info. I know the only way to know about the front diff is to pull it
. Thanks means pulling pulling apart both ends and sliding the axles out right? I should have pulled it when I rebuilt both knuckles.
Great info on the bumps, I completely forgot the I could limit the travel. There really is no reason to get the 2" bumps. Ill give a call the manufacturer to ask about a final limit bump. Thanks for the help!
