transfer case engaging going down the highway
02 F350 4X4 280k
Never had any issues before today but started a 2kmi trip yesterday and about 200 mi into it 75mph, looked down and the 4wd light was on. checked switch position it was in the 2wd position so I stopped put truck into 4wd and into low range then back into 2wd... all shifted fine so I took off down the road again. got up to speed no more that 1/2 mi down the road I hear a grinding noise and I think the transfer case locked in and the 4wd light was on again. as I pulled off the light went off again as before.
I put the transfer case through the motions again and when in 2wd I unplugged the motor on the transfer case. rest of the trip with no issues, unplugged.
I guess I will be looking for a short somewhere tomorrow, but I wanted to post it up to see if anybody has had any of the same issues to give me a starting place.
