4wd trouble with 75 chevy - Pirate4x4.Com : 4x4 and Off-Road Forum

i am really gonna sound like an idiot but i would appreciate any advice and help. i got a 75 chevy scottsdale with 4wd, a straight axle, and locking hubs in the front. i can't figure out the 4wd because every time i shift into it from nuetral, there is a loud grinding sound and sometimes it will shift into 4wd from park without a problem. i just got this truck so i am not familiar with its 4wd mechanism or the locking hubs and i would appreciate any info you got on this.

Is it a NP205 t-case? Do you know the shift pattern?

its a 208 alluminum transfer case. the shift pattern for the 4wd?

NP208 in a 1975, neat. Try putting the transmission in neutral with your foot off the brake while shifting the t-case.

i have a 75 chevy scottsdale with a bad speedo cable which i am trying to replace. After unscrewing the end attached to the transfer case, i found part of the cable was torn off and stuck in the transfer case. Should i just yank that piece out or am i supposed to unscrew it?

Unscrew the cable from the gear housing. Both screw together and bolt into the transfer case. If part of the cable is stuck in the housing, pull it out.
