Think i might have problem

So I'm sure I've read somewhere that if when turning and the front axle keeps hopping( crow hop?) it usually equals bad u joints. Am I correct?
Btw all this happens when I'm in 2wd not 4wd.

Any help would be good, thanks

This may be asking the obvious. But are you sure the 4wd is disengaged?

Weed hopper- im sure it's disengaging I can hear the thunk it makes after you turn it off. But it's ok the obvious questions are usually the source of the problem.

There could be many things that cause that... A worn out linkage piece, bad joints, or someone was silly enough to put the greaseable style joints in. or even your tires could be causing the shift in the front end. If you aren't able to have a reputable shop check the front end from worn components. You could even run your hand with the inner and outer edge or the tire (contact patch) and see if the tire has high and low points. If so then you might have an alignment issue or the aforementioned worn part.

Ehh I doubt theres a locker up there. But I do appreciate the optimistic attitude haha. Thanks. Still not sure but I also notice something else weird when I get up to about 65-70 I get a weird pulsing vibration (not very rapid but still there) throughout the whole vehicle but I can defiantly feel it on the peddles

Any idea what this could be?

in all likelyhood you either have a bad wheel joint or both, depends on which side the hop is occuring on or you possibly have a bad axle. a broken tooth or worn axle can cause that hopping/clunking when turning. those are the two most likely culprits. a universal joint is on the drive shaft and wouldnt likely cause that though the wheel joints appear very similiar and someone could have meant those.
rule out the obvious like a chunk of missing tire tread or a stuck rock. basically look for anything obvious then crawl under and check between the ball joints behind the backing plate to the rotors. there is a plus sign shaped joint, it should not be frozen or wobbly. if either of these conditions exists, there is the problem.
next do fully locked turns at slow speed and see if there is a clicking/clunking on either side when moving forward, that would be an axle.
next, it could be in the differential. in the older style trucks where you had lock in and lock out hubs, locked in hubs would hop normally due to no disengagement when turning like a posi-style rear end has. that is why the locker was mentioned because it can seem like there is a problem but in reality its working normally, unless its stuck in locked mode.
