If you have the stock 20" Goodyears, then they are a big part of your problem. They are terrible in the rain. If it looked like rain, mine would start spinning. I got rid of them for some Cooper LTZ's and I'm no longer scared to drive in the rain! The backend will still get loose if I hammer it and turn, but that's going to happen in a rear wheel drive truck with no weight in the back.

I know the GM front diff bearings with the all time 4wd doesn't take long to be completely worn out we've replaced them in my buddies 06 silverado twice already.
I had one of those systems in my 99 Exploder. It actually worked pretty well. It would use the ABS sensors to detect wheelspin (when the backs were turning faster than the front) and would engage an electrically-controlled clutch in the transfer case to tie the front drive shaft to the drive train. It did it so quickly that you didn't notice it. And, it would "pulse" the clutch so that the drivetrain wouldn't bind up on turns.

The upside is that it was great in the winter up in Ohio. It also allowed me to blow the doors off a Corvette one rainy afternoon (I had traction, he didn't). But on my vehicle, you couldn't select normal 2WD at all and all that front drive train was always turning, which knocked 3 or 4 mpg off the mileage.

Good Call, I do have the original 20in Goodyear Wrangler HP on there with about 50000 miles on them. I am getting new tires soon, I am looking at the Firestone Destination A/T. I have heard a lot of good things about them.

And I am not that worried about driving in the rain, on the account that I live in Arizona. So, it doesn't rain much and when it does it pours, so i would need 4WD regardless of the tires I have on there.

If you need to switch in 4x4 to drive in the rain then you have no business being behind the wheel

Haha that's the truth. I'm from PA where a three feet of snow isnt a snow day for kids but I moved to Phoenix for a few years and went to college there and its true when it rains its torrential downpour but people act like its a snow and ice storm. The whole city slows to a crawl.
