New here to the forum. I have a 1980 4x4 20R, 4spd. Long bed. It's stock with 89,000 miles on it. New to me within the past few months. Original owner/PO didn't drive it for +/- 15 yrs. Have given it a tune-up and minor maintenance and it has run well. Shifting into 4H and 4L however, are not engaging the front wheels with the hubs locked. Was thinking possibly pulling off the hubs and taking a look. I haven't encountered this problem before - suggestions on where to start will be appreciated. Thanks.
