No 4WD HELP

Long Story Short:
2000 F150 SCAB 4x4
Just changed all Ball Joints adn Tie rods and Upper COntrol Arms
Driver side Hub Hub Bearing and CV Axle Driver Side
New Tires and Wheels
Allignment

Went to the Mud Hole and all started great...Til I got Stuck

Tried to get pulled out Loud Pop On Pass side Front End
Front Tires stopped pulling
Got out and there is no snapping or popping while in 4WD Transfer still engages and gears down

However after cleaning it up I hooked a chain to a tree and then to the reese hitch. Put in 4WD pulled chain tight (5 ft or so) and got in the gas.
Rear end pulls great but no pull in the front.

Once again I have driven roughly 50 miles in 2wd and there is no weird pulling poping nor smells. when in 4wd everything acts nonrmal, but the front is nont pulling.

Question 1 how far fwd do I need to go before the front end engages?
Question 2 tearinng it down tonight after rechecking with the tree if it is still bad where should I start?

Thanks guys...Also posting in The 97-03 forum

I am wondering if you tore the hub apart on that side. Or maybe even something inside the front differerntial for a lack of a better word. You could try to put it up on blocks and see if the hubs are actually locking by locking them in 4 and seeing if they spin in opposite directions(did this last weekend with help on here). if they dont then your one of your ubs is not engaging. That is where I would start. I know you will get more help than I can give you though. Good luck!

Sounds like you might have busted a hub. If it's an OEM hub they are not the strongest out there. I agree with navyfordman about putting it up on blocks. You should elevate the entire front end and then lock only 1 hub. With only 1 locked spin that tire and see if the axle shaft spins with it. I am assuming the right side might be the culprit since that's where you heard the *pop*. I would check the left too while you've got it up anyway just to make sure.

There are other things that could be wrong too (*pop* could have been inside the transfer case) giving you the problem, but at least it's a good spot to half-split your troubleshooting and it's a free diagnostic!

Best of luck.
