4x4 not engaging need help

[Drewtay]

I have  a 02 gmc 1500 HD with the 246 transfer case  when I push the buttons it sounds like it is engaged but 4x4 won’t work

What kind of sound does it make that makes you think it is engaging? Does the front driveshaft spin when engaged? This could narrow it down to an issue in the front end and not the Tcase.  If the front driveshaft doesn't spin, then your issue is in the Tcase or the solenoid that shifts the Tcase. Also maybe get it on a lift or jack stands if possible to easily see if the wheels spin

No the drive shaft doesn’t spin the t case sounds like it is engaging but it just not driving the front diff

No the front drive shift doesn’t turn when the truck is on the ground but I have 4x4 when the truck is lifted up I can hear the solenoids working when I engage the 4x4

Sounds like the Tcase clutches are shot.

Are they easy to fix

If that is indeed what it is, a rebuild is in order. If you feel confident in removal of the Tcase, there are a few YouTube videos that show the process of the rebuild.  It's not super complicated IMO. Might be worth trying to find a junkyard or used one if you aren't confident on the rebuild,  and then it's just a matter of remove and replace.

I’ll probably pick one up until I get mine rebuilt
