Default 4WD Not Working

I recently discovered that my 4WD was not currently not working on my Hardbody. It will engage the gears 4L and 4H and drive like the 4WD is working but when i had it on the lift i discovered that the front drive wheel was not turning. Any good places to start?

Welcome to Infamous

Were the hubs locked when it was on the lift? Auto hubs normally require 1 revolution to lock.

If auto hubs they take a revolution or two to lock in. Mine never really felt solid so I swapped on some manual hubs.

I assume that the front drive shaft was spinning as were the front CVs.

Sounds like a problem inside your front diff. any sounds or noises coming from the vehicle while you did this? did you have 4WD engaged or spun the driveshaft by hand?

OEM manual hubs or aftermarket?

Have you ever removed them to clean out any crap that has build up? If you do clean them, a very light coating of grease is all that is needed, more is not better in hubs.

If your driveshaft is turning, but neither CV axle is turning, I strongly suspect something is wrong in your differential.

With the hubs locked in, and the wheels off the ground, turn one wheel by hand and see what turns. If the other wheel turns opposite, have someone hold that one while you try to see if it turns the driveshaft.

if the hubs are not locking it could be the hubs

I have not tried to clean out the hubs yet! i am assuming they aftermarket hubs! Also i tried to spin my front drive shaft by hand with it locked into 4 wheel high and its not turning! But it turns when the truck is running in 4 wheel high but nothing else turns up front!
