you took your 4x4 apart just before a winter storm.....
excellent!
I just got my back together (whew).... however, in the interest of full disclosure, I also have an awd bmw wagon, and Land rover, and a 4x4 lifted chevrolet pickup - so I certainly won't be stuck even if the '3 is down
HOWEVER
there is a story behind my 4 wheel drive team. I used to have just one - and it snowed 3' in one night. I figured (smuggly) that I could break the road out with my 4x4 then drive out in my company astro van. Uh, no. I always wondered what the clicking sound I heard from the front was - I learned - as the back tires spun and the fronts were doing nothing.... the drive shaft splines were stripped. I made it another 10' before I loud 'BANG' ended all progress. I took 4 teeth off the rear ring gear. For those counting I went from 4wd to 0wd in 10' I had to use the van to pull the truck back into the yard. Then, after turning around under a large douglas fir, I proceeded to drive from my home to work without a problem. I didn't even need to break out the road. Since then, I've had options.
