4x4 Not Locking In?

[kawaboy13]

So when oil comes out, do I need to add more? and where? That wasn't stated in the write up. And what type of oil? Thanks

[Bounty Hunter]

A minimal amount of gear oil will come out, shouldn't need to add any back. You can check/add the gear oil at the differential cover fill hole. Use whatever weight gear oil you normally use in the diffs.

 

If you do this with the jeep parked on a slight angle down toward the driver's side, less gear oil will come out.

Alright thanks. So I should just pull the vaccuum lines off the CAD and tie them up? And what do I do with the holes they were connected too?

[Bounty Hunter]

Yes tie them up.

 

Find the red vacuum line from the intake manifold to the transfer case. Cap it at the manifold. You don't need to cap any other lines.

[kawaboy13]

And how will the transfer case then be engaging? And the holes on top of the CAD won't fill with mud, water, or trash? Is the capping of the red line mandatory?

If you don't cap the red line you will have a vacuum leak. The transfer case is engaged by the lever inside the cab.

The transfer case engagement is still mechanical with the lever inside the jeep.

 

You can remove the vacuum harness from the vacuum switch on the transfer case. Water in the switch will not enter the transfer case.

 

Cap the red line from the intake manifold to prevent a vacuum leak.

I am also getting ready to do this, what is the best way to cap the red line?

[kawaboy13]

I never found the red line, but I did slide the Cad over and my 4x4 does work properly. Th only thing I'm worried about is when I reinstalled the cover upside down, it pulled it back over a little to the right get the fork in. Therefore, its not completely to the left side because of where the forks holding it. Will this strip the edge of my splines or is that normal? Also can't the fork slide back to the right, disengaging it, since all I did was turn it over as I was told to? And should I add more oil into the diff? What kind? And How do you know the fill line?

[Bounty Hunter]

It will stay engaged just fine, flip it and forget about it.

 

Trace the one vacuum line from the transfer case to the intake manifold and unhook it from the intake manifold. Then cap the vacuum port on the intake manifold.

[kawaboy13]

Alright and what all do I need to greease and add oil to on my front end?

[88pioneer]

As said before there is a fill whole on your differential

[kawaboy13]

So do I fill it up to the top with diff oil? And can I drain it from the bottom and put all new diff oil to the top?

[mvusse]

The fill plug is about halfway yp the differential cover. to drain it you would normally remove the cover, then clean up the mating surfaces good and put the cover back on with a bead of RTV between it and the diff.

 

Another way would be to pump the oil out through the fill hole using a hand pump.

 

To fill it, pour/pump/squirt the gear oil into the fill plug until it starts to run out of the hole.
