I was looking at ex forest service Rangers at a local auction and several seemed to have problems of this sort.
One truck (a 01) I was interested in was stuck in 4wd Low and the switch did nothing. Another (a 99) did 4wd high but no 4wd low.
Looking at the questions above and observing the vehicles behavior at the auction it seems this design is problematic?
Does anybody have any ideas what goes out and how to fix it? Thanks |
