No 4WD - Looking for advice
My 1986 F-250 (4WD/4.10/5.8L) is not going into 4WD, the front wheels will not turn.
I can rotate the front drive shaft in 2WD, but it does lock in when in 4WD, so I don't believe it is the transfer case.
I jacked the front end up (1 side at a time) and locked the wheels. I could still turn the wheels freely, and it didn't seem that locking the hubs had any impact.
Any ideas?
Thanks,
Greg

ya they sometimes break.... but try putting the t case in 2wd and the hubs unlocked and rotate the driveshaft and make sure both axle shafts turn to be sure your front diff isn't screwed up.
if you have to replace the hubs go with aftermarket ones. they are stronger...like warn or milemarkers.

Should the front tires be off the ground?
what axle shafts are you referring to?
sorry for the stupid questions.

i think what our friend is trying to say, is to make sure both of your front hubs are unlocked, and your transfer case is in 2wd. you'll have to crawl underneath and then try and turn the driveshaft that goes from the t-case to the front pumpkin. you should be able to see the axleshafts that go out to the front wheels turning, since the hubs are unlocked. if that works, then try the same thing, but with both hubs locked in. if it turns in both cases, then there is probably an issue with your hubs. its pretty common for the hubs to go, there is a designed weak link, an aluminum piece inside that transfers the energy from the axleshaft to the hub assembly, it was made so that the aluminum broke before the axleshaft or differential breaks. keep us updated, it can be frustrating.

pumpkin: common nickname for a differential. it should be a part of the front axle assemble, slightly driver's side of the centerline of the truck. it holds the ring and pinion gears, which transfers power from the driveshaft to the axleshaft. it is large and heavy. on the TTB suspensions, the differential is bolted on to the driver's side arm of the suspension. find where the front driveshaft stops, one side should be the transfer case, the other side will be the front differential on the axle.
