4Lo Locked no P.S

[SteadyT3ddy]

Took the truck wheeling today. Had a problem, When the vehicle is in 4LO locked i have absolutely no power steering and feels like Im steering 50's. When vehicle is taken off 4LO and unlock the front the power steering frees up and able to turn. Any suggestions would be appreciated.

You got a front locker? If so, then yup, that's how it goes.

Locking the differential or locking the hubs?

If you're trying to turn with the front diff locked.... it ain't gunna happen. The outer turning wheel has to spin faster than the inside. That's why we have differential gears.

no real connection with being in low range.....but assume you have some type of locker in the front axle as others have suggested. If not it sounds like you have a p/s pump issue.
