Weird Dana 30 shafts

Just bought a basket case 1993 YJ over the weekend for my wife. Havent really had a chance to tear into it much as there are 2 in line in front of it . I did notice that the front inner axle shafts seem splined on the yoke end. I have seen that on high end axles, bet never a Dana 30.

Itís got the CAD, the vacuum lines are cut, the front axle engages. Iím assuming itís got upgraded 1 pieces shafts in the front, just curious what they are/if anyone has seen them?

Was that done on the stock shafts to hold the plastic washers in place that protected the end of the tubes?

If the cad was in the locked position when the lines were cut it stays that way.

The plastic washer that keeps debris out of the tube?

I did not know that. Makes sense though as its a bit jerky full lock in 2wd. I just chocked that up to "its a jeep thing" and the jerking was the frame collapsing


I really want to leave this thing alone till I have time but I may have to pull a shaft and see.

I had a set like that previously. I have no idea what year they're from, but they were 1 piece shafts, so I think they would have been 95+

Aside from that I don't have any more details for you. I never ran them. Ended up giving them away when I tore out the D30.

I found a few more pictures. Overall they're beefier than the normal shafts, though they still neck down near the carrier splines.

Happy to help. Sorry I don't have more info. I just assumed they were later model shafts and was planning on running them while keeping the others for spares.

That's enough info to keep my mind from wondering too much. Cause it will go from "I'll just pull the shafts and check" to "Honey, I gotta drive 120 miles to pick up this LS and link mount kit I found for cheap"

Those are shafts for a jeep equipped with four wheel ABS. It was optional in 1994 and 1995 on YJ's. Also could have come from an XJ with the disconnect axle. The splines are the tone ring for the sensor. If one piece, they could also be ABS equipped XJ, TJ or ZJ shafts. '96 + would have larger u-joints.

The vss tone ring has nothing to do with the 2x spln shafts. Ive worked on hundred if not thousands of jeeps. Ive never seen those. They are not stock shafts.

Definitely ABS tone rings. I yanked a shaft from an XJ in a junkyard for a spare one time and it had those splined rings on the end of it. I donít recall if I ever actually used it on my YJ or not. I think I may still have it floating around someplace. I have never seen one like that on a YJ, they may well be junkyard XJ shafts though. Being ABS they should also have the larger joint found in the TJ if I am not mistaken. Pretty sure the abs shafts got the bigger joints.

They are all 297 after the 70s. Even todays jks are still 297/760 joints

You sure about that? They are 260 joints up until I believe the 94 or 95 YJ. TJs moved up to the 297 joints which is part of what makes the TJ shaft swap so popular for YJ guys. (In addition to the one piece inner on the passenger side allowing the elimination of the failure prone CAD). As I recall, the ABS equipped XJs also got the 297 series joints.

not talking about the stubs. The inner axle is double spline; yoke isnt part of the shaft.

"not talking about the stubs. The inner axle is double spline; yoke isnt part of the shaft."

Need to see pics of that if it's not the normal inner double splined shaft form the YJ right side two piece axle.

The pictured axles that GFY Racing posted are most definitely ABS axles. It's a very rare option on '94 and '95 YJs but ABS was available in those years and the outer stubs do have the tone rings, inner axle on the right side was two piece as they still had the vacuum disconnect system.

Lots of dumb people. “ThEy ArE tOnE rInGs”

My guess is they may be old aftermarket chromos. I spent many a time in the local yards pulling spare D30 shafts in my earlier years and have never seen one splined like that.

OP has a OEM zj axle shaft. Spicer presses on a thick plastic washer instead of the little flimsy ones most people are used to.

Can confirm. I have tried to take off one of those pressed on plastic washers. Itís a bitch lol.
