LB7: should front drive shaft spin in 2wd?

[MuscleTruck03]

I was messing with my truck the other day (after my front diff grenaded on me while driving down the road in 2wd) and noticed while in park the front driveshaft doesnt spin freely even in 2wd?? I checked my dads 07 and 06 and the both spin when in 2wd. Does it have something to do with my year or is there something wrong with my transfer case?? Also I checked the t-case actuator and it is working fine

Might be the actuated on the front diff itself

check the actuator on the front axle, it should be in when in 2wd
pull the plug on it & unscrew it from the front axle

 

[MuscleTruck03]

ok, just checked that and it seems to be good...

do you have a locker or spool or anything other than an open diff in the front? all u-joints good?

 

[MuscleTruck03]

Nope, diffs are all stock. I did have the t-case gone through... Think something could have been messed up then?

well I pulled the actuator off to make sure it wasn't fully engaging 2wd and used a wrench to shift the t-case and the front is still always locked to the rear... I've never been in a t-case to really know what would cause this.. any of you guys know? :dontknow:
