Part Time, Or Full Time??

[MEGALADON]

I have a 82 GMC. All stock, what is full time, and part time, and how do
you tell the difference. THANKS


PS, I was told I was on full time drive.

 

[beater_k20]

if its all stock, its part time. NP203 is the only full time case offered in 73-87 trucks.

 

[flatline]

if you still have the floor indicator telling you the gears


a fulltime unit (NP203) will have 4H N 4L : meaning you are always in 4wd but in high/low fashion.

 

[sweetk30]

if the shift nob has loc in the pattern its full time and 203 case. but it might have been converted at 1 time. and if no hubs just smooth cap and no emblems on frt axle hubs then 203 full time.

 

[beater_k20]

my 77 has lockouts and a 203

 

[sweetk30]

then it has been converted mostlikly.

the 203 was only offered until 79 so if it is orignal it would be a 208 transfer case which is a part time case

If I remember correctly, there are 4 options on my gear selector on the floor.

I do remember a neutrual to. I put it in 4L and tried to drive it on the street,
man, It jerked so hard when I gave it gas, my head almost went through the rear window LOL. SOOOOOOOOOOOO LOOOOOOOOOOOOOOOOW of a gear

i like the gmc grill my self. and thats all gm stuff. thats the current truck in buildup . its all in my profile. all sorts of goodys. that truck is a 500 doller special with 37k origanal miles on the frame and axles. the body is 138k miles from tenn off a 2x4 truck.

 

[sweetk30]

is your tcase cast iron or alum? cast is 203 and 205. alum is 208 and newer. but 203 has alum tail housing and 205 all cast except the seal holders.

 

[1979jimmy350]

a 203 should have five postions on the shift knob 4HI Loc, 4 HI, N, 4 LO, 4 LO LOC so if you only have four it should be a 208 which is part time

You may be right 1979, I don't want to sound like a liar, so I will see
when I get home, and let yaw"ll know tomorrow

[sweetk30]

dont need magnet. just look for rusty case and or silver case.
