Sounds like you have a bad CV joint, this will make a clunking or clicking noise like you described only when turning, and varies with vehicle speed.
Have it repaired before it breaks and leaves you stranded, or damages anything else.

SOURCE: clunking sound while driving
inner joints a plunging joints have problems acceleration jolts from a dead stop... the outer rezzepa joint clicks usually when turning thats the balls falling out trunion..... not usually clunking ... possible wheel bearings they are pressed in on front wheel drives... or even a tranny mount maybe ...it almost sounds like somethings loose ...its hard to diagnos online..srry i need more info about the symptoms...

When engaging the 4WD system, you are pulling the lever on the Transfer Case right? Not the transmission, it's a different gearbox.
There were several versions of transfer cases that used both full and part-time 4 wheel drive.
From your description this sounds like a part-time transfer case.
Going with that, it is somewhat normal to hear and feel a mild clunk when engaging 4WD high range, especially if you are at a complete stand-still or under full throttle.
Try engaging 4WD High while slowly rolling at idle - no throttle. It should pull in fairly smoothly.
Once 4WD is engaged it will literally LOCK the front and rear axles together. So do not do it on hard dry pavement.
These older style 4WD systems need a little "give" especially when turning. The engineers assume you are not engaging 4WD unless you are in a somewhat slippery scenario.
Many CV joints, axles, U-Joints, differentials, and transfer cases are damaged and broken by folks who don't understand this.
Reading the owners manual should provide a clearer description of what you've got.
Bear in mind that when you come out of 4WD it may not completely release, again due to hard pavement binding up the axles. You can try this: backing up 10-25 feet in a straight line, or getting one set of wheels on the shoulder or in some gravel. That should allow it to release the transfer case and go back to everyday 2WD high.
I hope this helps.

Normally the axle does have some end play. A bad bearing usually will give you rumbling noise and have up and down play if it's bad enough.Normally the seal will leak as well. Before you begin taking everything apart, get under there and put your hand on the axle tube nearest the brakes and try to feel where the noise is coming from while someone moves the bed. Listen carefully as well and check anything and everything for movement. The "hand on it" method will allow you to feel as well as hear the shift. I'm almost betting it's not the bearing.
