4X4 loud
This is a new to me truck, 2005 F150. I owned a 2002 before. When I turn the 4X4 on with the 2005 it is loud. Now it does have big tires 35's and is lifted it just doesnt sound right. Sounds like metal on metal. Anywhere I should start looking? Or is maybe just because of the lift and big tires?
Thanks,
Richard

metal on metal is never a good sound. it could be from the lift and tires, extra wear on the front axle, but it is not normal. i would remove the tires and check the front axles and steering. look for shiny metal. that is usually a good sign of where the problem is

Thanks for advice but have already looked for the obvious. Was thinking maybe its somewhere I cant see. Also would an issue like this send a code? I know Im reaching there but wondered.

Hm can you be a bit more specific?
Is it loud when going in a straight line or when turning? Turning in 4hi is bad unless the wheels can slip (i.e. rain, snow, mud, etc.)
Mine is loud between 25-30 mph and it's a common problem on the Tundras. I am going to get my diff replaced under the 60K mile powertrain warranty. Mine's only loud and vibrates the pedal when I'm in 2hi, and goes away in 4hi.
Post back some more specifics of the problem adn we might be able to help ya out a bit.

I have only tried the 4X4 in 4HI going straight and at under 30mph. Was loud enough I switched back to 2HI and the sound went away. This was on nice dry pavement, just wanted to make sure the 4X4 worked.

Hmm, well you certainly weren't "abusing" the 4wd, or getting any binding that could be causing that noise.
I'm not really certaint. Are all your CV boots in tact and what do your CV angles look like?
I know on some of the newer Fords, the Upper BJs and the CV angles can be maxed out pretty quickly.
And also, if it doesn't have one already, you should consider a differential drop (helps get those CV angles closer to spec)

take the truck into a dirt lot. then engage 4x4 and see if that sound re-appears.
when you engage the 4x4 on pavement you are causing binding. the front axle and rear axle are now locked together. however, hte wheels spin are different speeds. this will cause a torque build-up in the drivetrain...which puts stresses on different components. do this often enough and something will go pop.
since you are hearing a metal grinding noise, i am inclined to say that one of your IWE is messed up. or maybe just the 4x4 on pavement action pissed it off.
either way, moral of the story is NEVER USE 4X4 ON PAVEMENT UNLESS IT'S ICY OR SNOW COVERED. Dry and wet pavement provide too much grip for the tires. This prevents that drivetrain torque from being disipated by wheel spin since the tires can't spin.

While I agree one hundred percent with you, what's the harm in using it in a straight line? There's no way anything can bind up if he's nit turning, which is all I read saying. NOW,i might very well dre wrong and it wouldn't be the first time

Is the noise sort of like ice in a blender or sheet metal being dragged on pavement? If so, read through this thread to trouble shoot your IWE/4x4 system...

If you were stopped and then engaged to 4Whigh it is most likely coming from the front CV area. Turn the wheels to lock in both direction so you can stick your head between the tire and the wheel well and see if there is any grease slung up on anything. That will most likely tell you if there is a problem with the CV boot. You most likely will have to have a buddy slowly drive the truck in 4WH so you can listen for the noise. If it is the CV joint you will easily be able to trouble shoot it by reaching under and moving it around with your hand. The part isnt that expensive it that is what it is either. It also isnt that hard to replace. You will have to pop the lower ball joint, unbolt the flange from the front diff, and use a strong impact to remove the axle nut from the end of the CV axle.

It does sound exactly like metal in a blender actually. Im gonna find some dirt, gravel or something and give it a try there. What concerned me is my 2002 F150 hardly made a sound going to 4HI.

Your IWE's are bad they tend to stick after long periods of non use and then only engage halfway and grind off the splines. I make sure to at least engage mine monthly to prevent the issue. So far so good on my 2006.
