Well like I said My drive shaft is very loose (3/4" movement) It has me woried that the transfwer case chain is loose. other than actually taking it apart how can I diagnose this? any and all info is appreciated.

 

where is it moving? check to see if its from the u-joints, or from the points it attatches. is it moving at the rear diff pinion, or is it coming from the transfer case . which way is it loose. up and down or front to back

 

lets see it rolls back and forth till the drive shaft moves the tires, then it also moves a bit up and down (not much at all) I have noticed that when i put it in gear it shifts harder from r to d. but 4wd works perfect, and i do mean perfect.

 

Sounds like your u-joints are toast.

 

X2 on the u joints!

 

The u-jointsa do not seem to be bad and the movement seems to be from the transfer case. I could be wrong but thats what i remember seeing. I will look at them when I get home.
