Im about at my wits end here. My v6 98 Dak 4x4 has been having a very interesting string of problems as of late, and Im just about stumped. To start with, most of these problems only occur in 4x4, which has me even more baffled. Firstly, about a week ago my truck began to make a horrible racket when it was first started, which was later attributed to the fan blades hitting the shroud. It was very strange because my brother and I were out driving for a few hours picking up parts for his car, when all of a sudden it started making this noise. I have no idea why the blades would start hitting in the middle of the day. Anyway, we discovered that two of the blades were bent (probably from an off-roading incident a week before) so we bent the ends of the rest to prevent it from hitting. That worked for about two days when they began to hit again (I was dumb-founded). So i bent them more, they stopped hitting, then they started a day later, and I bent them some more and it hasnt done it since. Now comes the interesting stuff. It was raining two days ago, so I was driving around in 4x4 for better traction, cause I dont have any weight in my bed yet. When you turn the wheel till it locks in either direction (like turning into a parking space) the fan starts hitting the shroud SOOO hard that the engine almost stalls and the rear wheels (which has me even more confused because all the problems have been front-end related) lock up and pulse, like, lock, let go, lock, let go, etc. Then when backing up (also only in 4x4) the rear wheels do the lock-up thing again, but harder than in forward. The fan problem has been attributed to a slightly bent frame rail (the off-roading incident), broken motor mounts, and bent fan blades. These are all feasable, but leaves me totally hanging as to the rear wheel hang-up problem. If ANYBODY has ANY ideas at all, please let me know, I just want my truck to work again!! Thanks,

-Fox

I drive mine in 4x4 on pavement every few months. Never hard that problem. Why do i do it? Because it keeps things all lubed up, and it's recomended by the factory.

Dumb question - Do you have the same size or different brand tires in the front and the rear?

Also, are the front or rear tires excessively worn so as to create a difference in the diameter?

N56629: Actually, I just got brand new Michelin LTX M/S tires on all four corners about two weeks ago.

And as for the mount situation, the transmount is definately busted, I can lift the trans at least an inch with a crow bar, and the people at the dodge dealership say it shouldnt move at all. Also, the driver side motor mount (or a braket connected to it...I cant tell) is bent. Can anyone explain why a bad transmount could make my rear wheels lock up "only" in 4 wheel drive? I dont understand, the rear wheels are "always" on, so I wouldnt assume going into 4x4 would have any affect on them, but apparently im wrong...? Thanks alot guys, been great help so far.

sounds like broken motor mount or xmission mount could also be carrier bearing mount came loose. you need to go under vehicle and check your mounts for the engine set parking brake and open hood put it in 1st gear and release clutch partway watch to see if engine lifts abnormally high then try it in reverse for the other side mount

I had new tires put on my wifes toyota one time and they installed two different size tires. If you have'nt checked for this you may want to.

Even on a front wheel drive car that did not have traction control, the difference in sizes (only off by one size) caused major handling problems on this car.
