Re: Clanking noise in drivetrain (1970 4X4 c10 4spd).

To me it sounds like the coupling between the transmission & transfer case is worn & the output shaft is also worn on the tranny. On the standard trucks the splined output shaft & coupling only have about 2" of contact length and they get worn and have slop kind of like a worn out u-joint.
