Hello everyone I have a quick question. I have a 1987 f250 4x4 and 4 low works like a champ and 4 high works great when I can get it to engage. The 4x4 light comes on at the dash but only with a few tries can I get it to actually drive the front wheels. Could my linkage be damaged? I haven't got under the truck today due to the bad weather but if it's just an adjustment or a quick trouble shooting thing than I would try it. Other wise I'm gonna wait till this weekend when it warms up. But if you guys can give me a heads up on what to look for it would be much appreciated. And like I said 4wd works works great when it engages.
