the other day i was wheeling and got stuck in 2 wheel drive. so i put it in 4h and when i slowly dropped the clutch my jeep didnt move and engine was barely staying i live as i something was stressing it. it kind of felt as if my e-brake was tightly engaged. and when i put it in 4 low, when i dropped the clutch , nothing happened except clicking. For some weird reason this only happens when im in 2 wd and im stuck and i engage 4wd. when im just on regulary road, every thing works perfect. HELP ME PLEASE.
