My '05 sucks in the snow. I had to put it in 4 Low to get it up my driveway which is not hardly steep at all. In my '00 I had a limited slip and I thought I had one in the new one, but Im not sure I do. How do I check without looking? Door codes or VIN?? Thanks.
That is the first question that popped into my head. If they are factory Conti's the issue is probably more to do with the tires then the limited-slip.
..... I had to put it in 4 Low to get it up my driveway which is not hardly steep at all......
Traction is determined by several factors... limited slip, locker, or open differential; what kind of tires with how much tread left; weight distribution (if you're not driving all the wheels).
High/Low range isn't going to matter unless you're trying to run an F250 up the grade using a 3 hp Briggs & Stratton; low range will do absolutely nothing to increase your traction; it just makes more torque available at the wheel.
My friend at work has an 04 PSD 3.73 LS with factory tires on it, and they only have 20,000 miles on them and they suck even with weight in the back. He plows snow for a living and keeps getting stuck, he's replacing the tires today. I keep giving him crap because his is a 250 and mine is a 350, I keep telling it must be the 250, you should have gotten 350 because my truck works awesome in the snow even when pulling a trailer.
Factory tires aren't gonna do much in any amount of snow. F350 or F250......traction is the most important thing in snow....which isn't going to be accomplished with stocker tires.....unless it's dry pavement, but even slickies will work on that!

Get some better tires (I like the Goodyear Wrangler Silent Armor) and you will get much better traction in the snow. I was driving around our shop in my 07 on solid ice in 2wd with my Silent Armors.
Hankook has a new tire (AT-M or something like that) that has a very aggressive tread for an all terrain as well. Looks like they would do well too. Seen them yesterday at my tire dealer since I was having them clean my 07.
I had Firestone Transforce tires on my truck last year and they weren't all that good. I put Michelin LTX M/S tires on a few months ago and WOW what a difference. The only bad part is that I can't do doughnuts in the same place for more than a few laps because the tread diggs down to the asphalt to quick. These tires work amazing!
The easiest way to tell if you have a limited slip (or if it is working) is to find a place that has hard packed snow, put it in 2WD and gun it. If you see two marks or your back end swings around then you have a locker/limited slip. If you have a one wheel wonder and just throws up a rooster tail on one side you have an open diff (or your limited slip isn't working).
