Check them for cracks, all the way to both ends.

Check them for cracks, all the way to both ends.

Or just replace them they are cheap. Also, pull the hub off and make sure nothing is binding. Where they hard to lock when you engaged them manually? Make sure the seals on the hubs look good also.

if you have a hand vacuum pump hook up the hose right at the nipple on the nuckle and see if each side holds vacuum. if they do then your vacuum hub seals are all good. next on the right fender wall you will see a solenoid mounted there with 2 vacuums lines going to it. i believe the red one is supply from the vacuum pump and the black one is the one that goes down to your knuckles.. if you have a vacuum gauge or pump hook it up to where the black vacuum hose connects to the solenoid. turn your ign. key on and turn on 4x4 you should have about 15-18 in of mg if not most likely your integrated wheel end solenoid is bad, very common on those good luck..
