Often when the truck is first warming up but occasionally when I've been driving for a while, the front end will make a noise like a creak you hear while walking up a set of old barn stairs as I crank the wheels to turn the truck. It is more likely to happen when I make a tighter turn. Is there something that needs to be greased or is it just a sound from something flexing oddly?

When driving in auto the 4wd service light comes on. If left in 2wd it does not come on

An alert has popped up on my dash saying "Service 4wd" the 4wd will not engage and there are no leads as to what this issue could be stemming from. Any help would be great Thanks.

Bad vibration at highway speed intermittently. Starts at 75mph and peaks at 80. Factory tires, rotate every oil change. When it slows below 70 vibration stops. Doesn't happen every time and is more pronounced in 2wd vs AWD/4WD. Had tires balanced last rotation and still happens. It feels like its coming from the font passenger side but is not visible from another car following next to me.

Communication errors, U0073, U0101, P0700 plus three other codes. All the dash warning lights go on, once the vehicle gets warmer, shut it off and turn it back on, only service engine light is on, won't shift. Clear/erase the codes, no service engine light on, shifts fine. Put in new battery. The ABS fuse was replaced earlier

Came lose and hit the transmission lines and gearboxs

When driving,I accelerated and an obvious hissing noise started under engine/transmission.no power loss,no warning lights,no shifting problems. I went under truck,but could not pinpoint the source of the hissing. Any ideas?
