Clunking in 2WD and whirling while in 4 WD

[old mechanic]

I hear a clunk comming from the front drivers side when I take off in 2WD! I hear a wure wure, wure wure, while driving in 4WD in Hi or Low!!! It doesn,t sound good!
What is it? HUBS?
My 911 question is, can I drive it in 4WD with this Wure Wure??? Its sounds fairly loud! I need to go out in the snow! Back and forth to check on a sick family member!
Shes alone and lives about 5 miles from me! What will happen if it goes completly? Would I still be able to use 2WD??? Sorry! I don't know much about 4WD!
HELP! LOL!

well mine went whirr whirr when i was in 2 and clunked when i was in 4 and my problem was those dumb auto hubs. have someone check and see if all four of your tires are spinning when in 4 on ice or any other slippery surface and again when in 2

Help!!! LOL! Can I drive this in 4WD and if something breaks will I still be able to use 2WD or will I get stranded??? I'll be out back and forth tonight!!! Should I use it???
The clunk in 2WD seems to be comming from the Left Front! The Wurr Wurr (sounds just like old worn out brakes and worn out rotor sound) but its not, seems to be comming from the right front!
BTW: All 4 tires are spinning and gripping in 4 WD!!!
