I have a GMC Sierra Classic 1500. It is currently an automatic and I am
wanting to convert it to a standard 4x4. I am unsure of the steps to do
it or how expensive it will be or if it is even worth doing. I know
there will be a lot of cutting and welding I just dont know how much.
If anyone knows of the difficulty and the steps in doing this please
let me know.
Not really worth it unless you have a LARGE budget. You will need just
about every piece from the pilot bushing to the transfer case. Regearing
front and rear diffs as well. You would be better off selling or
trading into a stick if that is what you want.

Actaully it is not that bad to do if you find a wrecked or rusted out
donor truck for drive train parts. If you do you can bolt together in
a few days at most. If you have to do it a piece at a time, it can get
I have an old Jimmy that was a standard 4x4. I am not sure of the year
but I do know that the two trucks are pretty close together. The motor
was wrecked but the transmission axles and transfercasing should all be
good. I did not know if i would be able to transfer them all over or
If it is a 67 thru 87 it will transfer over gearbox wise and if it is
a 73 thru 87 the cross member and other parts will swap over too.
There was basically no change in frames from 73 to 87. They changed
tcase style in 81 but if you are using tcase and tranny and
crossmember it will bolt right in.
It is doable with a donor truck because the basic frame is the same
you will just have to unbolt and remove front suspension on 2wd and
then drill out rivet hold spring perch hardware on donor vehicle and
bolt them to your truck with grade 5 hardware or better. If you have
good tools (especailly some good air tools) some jacks and room to
work and a extra set of hands it is really not that hard to do because
it is basically a bolt on thing. (just lots of bolting) Older chevier
are about the easiest to do this to (not that any of them is easy) but
I would not even try this without a donor vehicle.
