I observed the shifter cable at the transfer case while someone was cycle the hand lever and it was obvious that the cable was not shifting the transfer case. The cable looks brand new, maybe just needs adjustment. I ended up disconnecting the cable from the transfer case and engaged high gear by hand. A test drive showed an improvement, but not much. She definitely has more pep in her step, but with the pedal to the floor I was only able to reach 31mph.
I do another test drive and check for heat the hubs. Thinking about replacing the fuel pump as well.
