I have a 2003 f150, I had the shift fork replaced and now the 4x4 doesn't want to disengage properly. It goes into 4H and 4L but when I flip the switch back to 2WD it either takes quite a bit of time(minutes, not seconds) or won't switch back until I stop and back up(sometimes this has to be done more than once also) Any ideas?

 

The idea is to recheck the work just done for an issue.
Sounds like it's hanging up.
Good luck.
