Was giving a tour of our farm this weekend to extended family, and was cut short because my 4wd would not work. Shifter and hubs worked fine, driveshaft was turning, but no spinning of the front wheels. This was in both 4wd hi and lo. Hubs trurned easy into the locked position and did not hear any grinding from the front diff. If anyone has any ideas of what my problem might be I would appreciate it. Thanks, Dan
