Front axle help

Today I attempted to install the cable lock on my stock Dana 30 axle. Any ways when I opened the cover where the shift fork is the gear oil was pretty much like grease. And when I tried to push the collar over just to see how it slid I noticed that the axle on the driver side was about an 1/8 th of an inch lower than the other axle. What do I need to do to fix this?

The inner shaft is recessed to accept a nipple from the outter shaft. With these mated together they should be lined up to allow the collar to slide back and forth. If the nipple broke of or the shaft isn't in all the way I suppose it's possible that they wouldn't be level. I would take the outter shaft out and inspect it. Also sounds like you have water in your diff. Probably need new seals on both ends. If your gonna change the seals you might wanna think about doing tj shafts and forget the cable system (mine failed on me).

What rob said, except that on my 87 the inner shaft is the one that has the "nipple" on it and there is a recess on the end of the outer shaft that it rides in. This is what keep everything lined up so that it will shift smoothly. (collar will slide)

Some people put grease in the CAD unit because they think that the lube from the differential never makes it that far. But it does. And the grease makes it hard to shift when its cold out. I would clean all of the grease out of there, cause it will mix with your gear oil which isn't a good thing.

The TJ axle shaft mod replaces the 2 piece system with a single long axle shaft. I did this to mine. If you are considering this mod, get the shafts for both sides since they run a bigger u-joint than that of a stock shaft. But, its expensive, mainly because you have to get a balanced front driveshaft, or have yours balanced.

My front driveshaft slip yoke was wore, so I just went with a new Tom Woods shaft.

How exactly do I get to the outer axle so I can see if I can push it in all the way or pull it out and check things.
