4x4 problems 2004
First let me say that my truck drives amazing! 99% of the time I'm in 2wd drive, but I try to put it in 4hi every month or so, just to keep things working right. Well today its been raining cats and dogs, and theres about an inch of water on the street. I got sick of spinning my tires at every launch, so I decided to cruise it in 4wd.
I'm going about 20mph when i turn it on, and everything is driving smooth for a couple miles or so. I turn into Mcdonalds for a coffee, while still in 4wd. As i'm turning and slowing, it starts shuddering and jerking, almost as if the truck is making its self stop. After my coffee, i get in my truck and start experimenting. Get back up to about 30mph and put in 4x4 again and its fine! Smooth sailing, I drive for a mile or so and then pull into another parking spot. Its starts shuddering again when I slow down to stop. Its like ABS is kicking in or something but I don't think thats really the case....
Is this normal operation? I admit I only use 4wd on occasion when I'm in tight spots, so I'm not sure hows its supposed to feel. Should I not be using it on the pavement, even though its wet and I could use the extra traction??
Any help is appreciated...
