I'm looking at a 97 Pathfinder; clean inside and out; solid underbody; runs great. Problem: Once in 4wd, it does not want to shift back to 2wd (or at least not without
great effort). When trying to shift lever from 4H to 2H, it feels as though it is hitting something solid and absolutely refuses to go into 2H. Any ideas on this one? The present owner just says it's been acting funny like that for some time but is otherwise ok . . .

Thanks in advance for the help.
