OK, here's a weird one (truck is a 03 TB LS with the 4.2). 4WD worked when I bought the truck, used it once or twice over the years during the rare snow storm, got the driver side front axle replaced A few years back now and the next time I can recall switching the truck into 4 Hi after that (while doing about 20 MPH or so was in my neighborhood so wasn't going to fast) the Service 4WD light came on and it became almost impossible to turn the steering wheel (like worse then a car with power steering that has completely failed and the belt is still attached), took all my might to turn onto my street, I was able to get it out of 4WD after pulling the fuse under the hood that forces the reset of the TCCM. Some time after that I tried it again and the same thing happened and it took several pulls of the fuse to get it out of 4WD that time. So I said OK my 4WD is broke and just decided to not use it, fast forward to last year, i'm replacing the rubber brake lines on all four corners, we've got the front end up in the air doing the front brake hoses, I switch it into 4 hi but the wheel turns easily but the service 4WD light did come on but it shifted out of 4WD without having to pull the fuse, but I did pull the fuse to clear the light, fast forward to just now, I decide to run up there and listen to see if the actuators could be an issue, I hear clearly both actuators and it successfully goes into A4WD and 4Hi, crank the trunk and take it for a spin around the block, steering is stiffer then 2WD so I know 4WD has engaged but as I drive it it feels like the steering is getting stiffer, not as bad as it had been before when the 4WD Service light came on but much stiffer then it was when I first rolled out of my driveway in 4hi a few minutes before. What could cause the steering to get harder to turn? Good news, it easily came out of 4WD this time, no fighting with the fuses and no Service 4WD light. when it starts doing this it also takes more throttle to get the same amount of movement, it's almost like something is seizing up slowly when in 4WD.
Anyone ever experience anything like that?
