The tranmission made a loud clunk sound and then wouldn't go forward. But runs in reverse fine. I can hear the tranny engage. Just won't move forward...
Check the caliper if it is stuck and also check out the front axels and the best way to do this put the front end on jack stands support the car in the back and if the wheels move freely then the problem is in the transmission check the fluid and the linkage on the transmission

Wow. A snapped side shaft sounds serious. If you lift the front end of the truck, (or the rear end for that matter) the wheels will appear to be counter rotating, it is the way a differential works. If you turn the left wheel forward, the right wheel will turn backwards, and vice versa.
When you change to 4wd the front end does make a rather loud clunking sound as the gears engage. You should therefore change while the truck is stationary, then slowly move forward or back until the 4wd engages, then take off.
If your truck went OK on ice, it should go as well on pavement, just don't try to engage 4x4 while moving.
If it is an automatic transmission, first check the fluid level. If it is low, fill it up and try it again. If the level is fine, then there is a bigger issue and you should seek a professional's help.
What kind of noise? A clunk, chatter, whir, grinding, or what? If it's a clunk, you may have a worn U-joint. Test by holding brake on and change between drive and reverse and back. If you hear a "clunk" when the tranny engages, it's probably a worn U-joint. Not a hard repair to do in the driveway. Always change BOTH front and rear U-joints - if one's worn, so's the other.
Your sun gear shell (google it) has broken in your transmission. I'm guessing you only have 1st and 3rd forward gears? I have a 98 Z-71 and have been through 3 of them. The OEM shell is junk. When you take it to the tranmission shop, tell them to replace it with a hardened shell. My local transmission shop charged about $450 (parts and labor) to change the shell only. The very first time it broke (about 65,000 miles) they went ahead and rebuilt the tranny while they had it apart. If you've never had your tranny rebuilt, I reccomend doing it while they have it apart - they probably will, too. I have the advantage of knowing my mechanic since I was born (small town). He is as honest as they come and this was his suggestion.
Since he put the hardened shell in mine, I have had no problems.
Sounds to Me Like There is a "U" Joint Problem Here. Although normally it would "Clunk" upon Engaging Forward or Reverse, I would RULE OUT This FIRST, Then move on to Motor Mounts, Transmission Mount, Then DIFFERENTUAL= Pinion Bearing ETC.
