i cant get it to shift out of low range 4low. is there a trick to get it to shift. it has been working great and we dont use it too much. 90000 miles on truck. thank you sherri

Make sure your steering is nearly dead straight and move/roll the vehicle slightly while bumping the lever. Basically 4wd lacks a center differential and if you turn on non-slippery conditions(95% of time with part time 4wd) you stress the transfer case making shifting difficult.
