221 transfer case any experts?

[61K10]

having problems adjusting my t/f case shift linkage. seams to (at times) to not want to go all the way into 2hi. (not hitting the floor) seems like 4hi gear is rubbing not completely disengaged. Make an offal squealing sound. any thoughts? also when i had it on jack stands (all for wheels off the ground) running in 4hi the ft driveshaft is bent. could see it moving up and down some. new r&p in ft axle and new u-joints. No dents are scrape marks on d/s. It never ends lol!
