2wd vs. 4wd

I just purchased a certified 07 Envoy SLT 2WD. It was a last minute purchase as my previous car was totaled. I live in the Chicago area- I am kinda kicking myself for not searching more for a 4wd.
I have never really needed a 4wd- not even in the most recent blizzard.
For those 2wd owners- how does it do in the snow? Towing? etc

I never had any issues driving my 2wd TB in snow. I stayed on main roads and used good sense about where to drive. That said, I was in Virginia. We had a few good storms, a couple of ice storms, but NOTHING like what I have driven through in Chicago. I did however drive my civic through some pretty good Chicago storms without any problems either. I think it comes down to how experienced you are are.

I remember the first snow my TB saw. The wife and I were leaving Norfolk heading for Miami for Christmas. We had about 8 inches of snow and ice crap on the ground. The TB wasn't having any problems.... save one. The window wash tank had frozen solid! You can imagine how cold it has to be to freeze that tank solid. For the first hour I had to stop every 10 minutes and wish the windshield by hand. It began to thaw after about 3 or 4 hours of driving, which was a couple hundred mile south, into warmer temps.

You'll have fewer problems if you got the G80 automatic locker option. Does your glove box sticker say "G80" on it?

If I recall correctly, 07+ models come standard with Stabilitrak, which combines ABS, Traction Control and Stability Control in its functionality. That should get you through most on-road winter driving situations just fine, you just need to take time, go easy and let the electronics do their thing. When GM developed Stabilitrak, for demonstration purposes they took two nearly identical Yukons, one a 4x4 w/o Stabilitrack and another a rwd unit with Stabilitrak and guess which one maneuvered the snow & ice covered course better? ..... If you guessed the 4x4, you'd be wrong!

Can't imagine it

My EXT spins the rears way too easily. I wouldn't consider it if I had to drive in snow. Maybe with real snow tires instead of all terrain tires it would be ok.

Some of the stabilitrak comparison videos are amazing. Total catastrophe without and maintain control with. My bottom line is it's a truck, trucks should have more than 2wd. That's just the Minnesotan in me. I've never known anyone with only 2wd on a truck. We subject our trucks to all the stuff you'd want more than 2wd for.

Go with snow tires in winter and you should not have to many problems. I had a 2WD Blazer with snows and had no problems in light snow.

Im orignally from Cleveland, OH. There were times I would use my 4wd but that was just me being stupid and trying to get stuck .

Most of the time I was in 2wd with decent tires and there were only a few spots I slipped but nothing big to cause an accident or cause the other drivers on the road to freak out

If by chance you don't have a G80 you're not completely out of luck. Since you have an EXT you have the same rear axle as a full sized truck, the 8.6" 10 bolt.

This means you could use this:

The installs on those are easily done in your driveway with simple hand tools. You'll have a fully locked rear axle that releases when you need to turn. That will help get you moving in the snow, and the Stabilitrak will help you continue to move in the direction you originally intended.
