I recently lost all my gears, it won't move but just grinds when put into drive or reverse but will shift to park or neutral no problem. Any ideas?

Sounds like transfer case failure

Tow it home or to a shop. It ain't going to move on its own.

The shaft that runs through the oil pan to the right side and engages into the coupler may be stripped out causing noise and a no drive condition!! Have someone get in and put in drive and you watch underneath and see if the front and rear driveshafts move

Yep its probably the Thru Shaft or Front Differential Axle Disconnect assembly that the shaft goes thru The AWD TBSS are famous for it I have had to replace mine at 95,000 then Built my motor and made to much power and had one made out of tool steel
