Need some explanations

[motox-010]

I kinda dont know how to explain this (you would need to talk to my step-dad) but he thinks that my Jeep is not all time 4 wheel drive, and that to put it in 4 wheel drive I have to move the lever to 4-hi. Can anyone explain how the drivetrain for my Wag works?

Need a little more info on what your Jeep has.

If it is all stock and an automatic then it has a quadratrack in it.- NO lock outs on the front hubs.
If it is a manual then I think those had the Dana20 in them. Lock in the hubs and shift it into 4 wheel high (IIRC)

If it is the auto and you have the front lock outs then someone has changed the quadratrack to a part time case. Only way to have 4 wheel drive then is to turn the switch in the glove box and lock in the hubs.

If it is quadratrack then it is always in 4 wheel drive. Only use the switch in the glove box when you are offroad or in a spinnng condition. Lever on the floor, if you have one, engages the low range for the transfer case.

That help any?

It is a 75 Wag with stock everything pretty much. It has the switch in the glove box, and the handle on the floor, I run it in hi (down). It is quadratrack. Now I need more people to come in with the same answer so I have more support.

no locking hubs?
if not then you have a stock quadratrack. You are in 4 wheel high all the time unless you pull up on the floor lever then you are in low. The glove box switch locks the transfer to distribute the power evenly front and back differentials. DO NOT run it in this set up on the hard surface roads.
There is no way too have a 2 wheel drive without removing parts.

The only way a quadra-trac is NOT full time is if it has been converted (milemarker part time kit) in which case you will have manual lock hubs up front.

[edit]
The way the QT works in default is full time 4wd via a Limited slip clutch pack inside the transfer case. The vacuum switch in the glovebox is a switch to go from fully differentiated (so it can be in 4wd full time) to locked (the same as a part time transfer case in 4 hi). The lever on the floor switches the case from hi to low, fully independent of whether it is differentiated or locked from the vacuum switch.

I KNEW I WAS RIGHT!!

My '73 is 2WD in stock form....no front shaft installed:D

I have a '77 J10 w/QT and I have learned to dislike the term "full time four wheel drive". I think it is more like "all wheel drive". The QT is transferring power to the front and rear as needed via clutch cones therefore it is a "limited slip" configuration; the axles are also dividing power between the right and left, as needed, limited slip as well. You will only have power to one front wheel and one rear wheel at any one time. If you diconnect the front driveshaft you will be dead in the water because all the power wil be transferred to the front. Only when you engage the emergency drive, will you then have "four wheel drive". Like a standard transmission with a transfer case, when you put it into 4hi or 4lo the transfer case is sending equal power to the front and rear.

Show him this. It's the Q-Trac Info link in Flint's signature.

Note the vacuum diagram on the page that shows the switch in your glovebox. It's the only stock setup you can have with that switch.
