Getting into 4 Wheel Drive

I recently purchased an '84 CJ7. It did not come with the owners manual. What is the correct procedure for initiating the four wheel drive system?



Thanks,

If posible I always stop let the jeep roll slightly and grab that little shifter and put er where I want er. 4 hi for the ez stuff and 4 low to get the job done. I can shift on a slow run if I need to but why take chance if you dont have to. To take er out of 4x4 I do the same only backwards up into 2wd then I always back up just a bit out of habbit. So there is the Tug method of going in and out of the 4x4 mode. Might be wrong but it has always worked for me. If I am doing this wrong guys don't make me look like a dummy I don't know any better

but I do know how to lock the diferencials on a road tractor if that will help

Okay, I think i can help here a little, as i just went through this whole discovery process last month.



First you turn the manual hubs on the front wheels CLOCKWISE to engage them.



Next you have to be moving forward SLOWLY with the transmission IN GEAR (1st or 2nd) when you push the "Transfer case" stick into either 4H or 4L. (I had some trouble getting used to NOT pushing in the clutch when i first started doing this)

When you do this, the "4 wheel" light should come on in your speedometer cluster (unless the light is burned out)



When going back into 2wheel, you just need to pop it back to 2H with the transmission in either 1st or second.

After you are done, you should rotate the manual hubs on your front wheels COUNTER clockwise to disengage them if you are going to be driving in 2 wheel for a while.



If your 4wheel is reletively unused, your transfer case will be a bit hard to shift until it loosens up a bit. It just takes a bit of practice.[addsig]

Thanks guys. For situations like snow where you may need to shift into 4WD during a trip, it would be convenient to lock in the hubs before one leaves the house to avoid having to get out in the snow on the road to lock the hubs if 4WD is needed. How far can one safely drive the vehicle with the hubs locked into 4WD mode, but with the transfer case still in 2WD? This way, if you want to go to 4WD while on the trip, you just shift into 4WD because the hubs are already prepared.



thanks,

leaving your manual hubs engaged genereally isnt a good idea. I mean you COULD do it, but you would be putting alot of un-necesary stress on the front differentials and T-case, not to mention really taking a hit on fuel economy.



However, I have seen that there are kits that allow you to engage/disengage the hubs from the dashboard while you are driving, but i dont know too much about them other than that they exist...

If anybody has any experience or recommendations on these, now's the time to speak!

I found an interesting article in regards to leaving your manual hubs engaged or not.

This person seems to think its not really much concern to leave them locked if you think there's even a remote possibility of running into bad roads.



Its a good read anyways
