47re transfer case
 

my truck has the manual shift on the and i cant get it into 4 low and also getting a weird noise whenever i go to speed up to go up a big hill not even hauling i dont know what the noise is at all. any help?? and where could i go online to find a transfer case i cant find em anywhere :argh:

put truck in neutral and shift it in low.

I did have it in neutral

Yep neutral usually helps get it in 4 low... If that doesnt help have you looked at your fluid in the transfer case? Or ever changed it?
