Bringing this thread back to life.If you end up needing one or both, you have another option. Remove the fork, collar and both gears and buy the one piece sleeve from an AWD truck. Your front axles won't disconnect ever again (slight loss of mpg) but you won't be fixing this again in a few years either.
I had a shelled out transfer case on my 04 Envoy. I changed it out, along with the motor and now it works in 4LO/2HI but the dash lights blink when trying to go into 4HI or AWD then the solid light goes back to the original setting prior to my selector input. I pulled off the front axle actuator and noticed that it extends fine in 4LO and retracts when in 2HI, but doesn't move when I put it in 4HI or AWD. I can feel the front axle is engaging and disengaging as the lights are blinking when trying to go into 4HI or AWD. Is this likely a front axle actuator or TCCM issue?
