Seems like i'm stuck in 4WD lever is in 2WD but feels no Different when in 4WH put it in 4L and i can Definitely tell it's in 4L 100% sure the problem is not the linkage but while in 2WH i'm jumping and Barking front tires when turning i did just install a sye last week but never touched the shift fork inside its Weird even if the fork moved to wrong spot i would think i would be able to tell anyone have any Ideas
