I have a 2K2 F150 extended cab XLT with the FX4 package. I has been awhile (about a month and a half) since I put it in 4 wheel drive so I thought that I would just put it in on the way to work just to make sure everything is going well. (I might have to use it this weekend) I drove through town today and when I pulled into work I notice that it felt like it was kind of binding up a little bit when I turned the wheels to park. So I backed up and drove around the parking lot a bit and whenever I would turn kinda sharp it feels like it starts to sort of bind up. Is this normal? Last time I used it was in a sopping muddy field and had no troubles at all. Performed perfectly, I dont remember taking any tight corners though. Any comment are greatly appreciated.
Your not really supposed to use 4X4 on dry pavement. As you experienced it puts a lot of strain on the components of the system. Your manual should detail the warnings regarding this.
I wouldn't worry about the wear and tear from a short drive like you described. Good idea to click into 4X4 every month or two but try and do it in the dirt or at least on your neighbors lawn
The reason that that your truck felt like it was binding is because when you turn your wheels turn at different speeds. When in 4wd the wheels are being driven and like to turn at the same speeds, thats the reason why it only did it on the "sharp" turns. While you are off road you don't notice this even on turns because there is less grip and the wheels slip a little. I hope this clarified why you felt the difference in your trucks handling.
The front axle ratio is a LITTLE different than the rear axle ratio, so that the front tires always pull the truck along, instead of being pushed along by the back wheels. However, you are right, when you turn the wheels, it throws the revolutions off, and thats when you get the bind up. It may bind up a bit on straight aways, but not noticible.
That's a first. Mine are 3.55 front and rear. If they were different, it would bind up inthe transfer case and be snapping gears, u-joints , axles etc. The two differentials should turn the same speed. The wheels may differ a little bit, but the spider gears or limited slip in the differentials will take care of that.

Sometimes the front and rear ratio s differ because the axles are different makes. IE a dana axle may have a 3.54 ration and the ford is 3.55. But they are the same.
Guys , can u help. I just yesterday got my first Ford truck...XLT 5.4L 4x4 crewcab.Anyway , my question is do these K+N type filters make any difference ?

hey Jimmy, do our 4x4 have a limited slip front axle? i thought i read somewhere that most 4x4's come w/ an "open" front diff. is this true? and how can i tell if my front axle is a limited slip?
I haven't really checked. I know that all 4 tires spin in the muddy wet grass. It should have an "L" on the tag where it gives the ratio like it does on the rear.
I'll check it and get back to you.

I too have an 02 F150 FX4 that was doing the same thing. Even in the sand. I took it to the dealer and they changed the transfer case fluid. Found some shavings but said that was normal (?). The fluid was off color, no explanation for that, and after the new fluid was in the problem stopped. That was a couple of weeks ago and I have been off roading with it since making tight low speed turns with no binding or clunkning.
