What fluid did you use?

The drive shaft yoke is dry on the transmission out put shaft. When you stopp it slides in on the shaft, and then when you let go of the brakes the yoke sides back and goes clunk. Remove drive shaft and lubricate the splines in the yoke.

Remove transfer case shield. Remove clamp on boot
where front drive shaft meets transfer case. use a flat
screwdriver to pry free end up and release clamp. (you need a special clamp tool to reinstall clamp )
Remove 4 bolts at differential end that hold U joint Retainers to yoke. Slide drive shaft to rear enough to clear yoke. then let drive shaft drop so it clears differential and slide forward until it come off transfer case shaft.

could be the baerings in the diff

sounds like the universal joints on the rear drive shaft

the parking brake rusts and makes a rubbing sound. it is inside of the rear disks. you have to remove the caliper then the caliper bracket. pull the disk off and inspect the parking brake. very common problemas most automatic trucks no one ever uses the parking brake

remove tire, remove caliper with 18mm wrench remove the rotor if it will not come off hit with rubber hammer

I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

No!!! Do not tow.
Unless it is a very, very short distance...do not tow. Are there lock out hubs on front? If yes, unlock them, and then remove the rear drive shaft from the rear end. If you can unlock the front hubs, then this will prevent the front differential from turning the front drive shaft to the transfer case. Then you can disconnect the rear drive shaft, and hang it somehow up high against the body so that it will NOT be HIT by the spinning connector yoke on the rear end. Leaving the drive shaft in the transfer case will prevent the loss of oil. BUT......It is critical that it completely clears the spinning yoke on the rear end... or else it will be damaged and may damage other things also. It is also important to remember that as you tow, the vehicle bounces up and down, so there needs to be several inches of clearance between the drive shaft and the connector yoke on the rear end. . If you do not have lock out hubs in the front, then disconnect the front shaft from the front end and hang it also. Use PB Blaster or similar oil to ease the process. If towing on a tow dolly, then you need to only remove the rear shaft. Be careful and make sure that whatever you use to hang the shaft is sturdy.
