I have an 2003 4x4 Supercrew F-150 XLT, with 42000 miles on it, just outside the warranty. Well, I purchased it used about a month ago at a liquidation car sale. At the time, I was happy purchasing the truck, considering I was able to get the sales guy to give me $8300 Trade-In on my 2001 F-150 4x2 regular cab with 95000 miles on it.

Anyhow... ONTO my dilema...

The new truck has 4x4 with shift-on-the-fly **** on the dash. I can turn the switch and the 4x4 light comes on and I hear a little click, but if I stomp on the gas, on the rear wheel spin, but it doesn't feel like the 4x4 kicks in. Even if I kick it into 4x4 low, it doesn't seem to lock in immediately. After about 3 minutes it'll kick in.

Just like yesterday afternoon, I backed up to a muddy fence by the barn, put it into 4x4H, and hit the gas, on the rear spun. Backedup and tried it again. I tried engaging it when in park, nuetral, and drive. But, like I said, after a few minutes, then it seems to lock in.

Any suggestions???
Thanks

I had the same problem on my 06 but a week later it fixed itself and is working fine to this day... i would just give it time or take it into the dealer and it shouldnt be that big of a deal i would think

I'm just guessing but check fuses first. It does however sound like the fuse is ok since you have the 4x4 light lit. You may have bad hubs. I think I heard something about others having problems with them.

Edit..DUH, I didn't read you post very well. It sometimes take a few to get the 4x4 to engage. I sometimes have to let my truck roll a foot or two for it to engage. I think your probably just seeing the normal delay that I've always seen.

yeah, I checked all the fuses already. I wonder if there is a way to grease the hubs or check the vacuum on the transfer case to make sure that is all working properly.

Thanks

while were on the topic... i used my 4 wheel drive today and once i got home, about two minutes after i used the 4 wheel drive, and i noticed this faint burning smell on the front drivers side of my truck should i be worried or does this happen to everyone.

Doesn't sound good. I haven't ever smelled anything in any 4wd truck I've owned like your saying.

LovetheTide

i hope it was just some grass that got cought up in the exhaust headers or something i HOPE

Look at that you got 100 post today . Good thing is you should still be under warranty if there is anything wrong. Tell the dealer the next time your there.

LovetheTide
