Hello all! 2007 dodge nitro auto, 3.7l
So I had discovered a couple months back that the front driveshaft boot was torn to all hell. Replaced it with a new driveshaft, the one off of 1aauto on google search for 170$
replaced it and everything seemed fine, no rattling change sound.. for about a week. The new driveshaft has the same problem, torn boot.
I noticed that the driveshaft has some play rotating about a half an inch. Not to mention slight play up an down less than a mm(due to no grease and bearings getting worn out.
so..
Is it something internal in the transfer case that needs to be fixed that will cause premature failure to the boot I.e the chain( with the 1/2 in play causing too much torque on the little guy?
Or I could of ordered too small of a driveshaft? ( it was about 1/2 in too short new, but easily flexed to fit, seemed natural. 🤷🏻‍♂️
also to make it more mind boggling, I do know I need to replace passenger sidecv axle on front(has slight rear in boot) will that cause it to tear prematurely?
ONE MORE question, can I drive it without front driveshaft? Doesn’t seem like it would harm anything, down know if I’ll get a 4wd light on. But I do know the front driveshaft spins no matter what even if not in 4wd. And obviously I wouldn’t be using 4wd if it’s disconnected.
So, wrong part ordered? Or loose chain in transfer case? Or total moron? Thanks for your input, looking forward to it. First pic is original , second(newer looking is aftermarket)

Ok ima take it out bc that rattling noise drives me crazy and nervous. But I think it might be my front cv axle boot being torn and having play. Dunno if I want to just diagnose it as that tho. I know I have play in park, engine off on the transfer case coupler., which I can imagine the 1/2 inch play over a short period of time, the torque would rip it to shreds. The front drive shaft spins even though not in 4wd but the nitro is full time rwd. Any other input? Confirmations? Is there a tensioner in the transfer case?? Anyone rebuilt it? What can I expect for parts needed and headaches to come? Thanks

Also with no movement on front diff, will it trip a sensor to say 4wd or anything along the lines?

No you shouldn't get any fault codes with the front shaft removed,
the torn new boot looks very dry, like there was no grease inside ?.
