new update. i put the truck up on jack stands( all 4 wheels ) and manually put it in 4hi then put it in gear. all 4 wheels spin but as soon as i hold the front wheels they stop spinning and dont keep spinning when i let go, even when i give they a little help. any idea on what could be goin wrong in the transfer case?

 

Check your front axles and u-joints on the axles to see if something broke. You may have snapped an axle, u-joint, or u-joint/axle yoke.

 

Did you hold and stop just one wheel, and if u did the other wheel will keep turning. If u don't have a limited slip diff or locker setup diff. the wheel with least resistance will still turn due 2 the spider gears transferring torque when the other is held. After u check that by holding each wheel seperately 2c if the other is turning and that checks out ok, then get a friend 2 get in the truck and give it some gas to apply torque to the drive wheels at a higher speed 40mph. Now all 4 wheels should spin and it would b very hard 2 stop one from turning. Let me know what happens.

yea i held both wheels and after i let go nether started spinning again ever when hitting the gas, just the back two spin.

 

check if front driveshaft is turning while in 4x4 while front wheels are stopped(if turning). If it does spin then u might have front diff problem (broken case pin or spider gears or broken axle). c if u can hear any unusual noise from front diff. If there is no output to front driveshaft to diff then the transfer case has an issue. If axles r cv boot type try 2 push in toward diff while in gear 2c if anything changes, but use caution while doing this as axle might catch.

 

ya im pretty sure that its a transfer case problem. the front drive shaft turns at first when i put it in 4x4 but as soon as i stop both front wheels it wont turn any more even when i let them go. lets like somethin in the transfer case is slipping or not engaging, cause i dont hear any grinding or anythang out of the ordinary. you know where i can get an exploded view of the transfer case?

 

go 2 parts dept. at dealership and they can print you what you want but tell them you need the printout 2c what your going 2 need 2 replace and buy from them. This way u shouldn't have any problem as sometimes they'll just show u the exploded view on their screen and ask want u want. Make sure u get the tag off the transfer case which is held on by one of the bolts. Also get vehicle door jam info ie: engine, trans. rear diff etc. code #s Any tags from powertrain will b usefull 2 them. I can't remember what your driving but I have good knowledge on Ford products.

Good Luck!

 

thanks for the help ill keep posted on what i find
