Ramcharger vibrates after using 4wd

I don’t know **** about the ram chargers. But I do have an 02 ram 2500 gas (2nd gen) with the 241 T case. I had a vibration after I slid it into 4 high. I pulled it back into 2 high but did not fully disengage. Had to adjust the shift rod to correct this. Other thing that happened is one of the u joints in the cardon joint let lose torched the front prop shaft..
