Going to a 2" IRO lift for 1st time. Do I need to worry about the front drive shaft?

Hey guys...1st time lifter, and have searched and searched the threads for all sorts of great advice. Thank you all!
I will be going with the 2" IRO lift with Bilsteins and all new isolators.
With that being said...I did come across a few posts regarding the front drive shaft failing after a lift. Is this common, or just a freak thing?
I have an '04 Limited (build sheet says I have a DJJS Dana 30/186MM Front Axle...not sure about my front drive shaft)...so if I go up to 2" of lift (maybe a tad more with new isolators)...do I have to worry about anything like this happening? If so...what else do I need to make sure the front drive shaft wont fail?
This Jeep will only be seeing some mild wheeling. Mostly a DD.
Thanks so much for the help and advice.

You shouldn't have to worry about it. The rezeppa joint fails after a while because of steep angles but at 2", the angle isn't too bad. I'd lift it and run the driveshaft as it is. If it fails, replace it with a double cardan driveshaft (third down in the picture).

Here is a chart to assist you in figuring out what driveshaft you have.

Cool...thanks for the help, and the pic! I really appreciate it. I was a tad worried...I have never lifted any of my Jeeps, and just wanted all the info before I go ahead with this, so I know what to expect.

Mine made noise immediately after my lift. I'd be ready for a failure. Of course mine has 165k on it so it might have been worn out anyway.

This is what I have read about. After the lift...noise, and then failure.
How hard is it to remove and replace with a double cardan?

Here are a few little snippets I found (and trimmed up). I don't know much about the swap but I know there is quite a bit of knowledge here on the forum.

This is nice because then you don't have to buy yokes and change them (which is kind of a big deal on the front diff)...

...Now there are always cheaper ways to do things...

If you have the CV driveshaft (and you probably do with a 2000) it will fail at 4" lift. You can go cheaper by getting a used OEM double-cardan shaft for say $100 but you still need yokes.
