Dana 60 help

Friend is having problems with his dana 60 with a spool here was his post in a different area.

Hey all, I'm slowly making my '99 2500 into a puller. I just finished swapping in 4.88 gears and a spool. I went this route because I figured with the CAD, I would still be able to turn just fine.

Now, when I go to engage 4x4, the passenger front will not engage. I pulled the CAD off and the actuator is working correctly. It pulls the fork and collar all the way to the left. I found that when the collar is pulled over, that if it does not engage with the inner axle shaft right away, it actually pushes the shaft in towards the carrier. The inner shaft moves away from the passenger shaft about 1/4-3/8" until the splines bottom out in the carrier and then the collar has no splines to engage in. I was wondering if anyone has had this happen before and/or know what I could do to resolve this.

I would just get rid of the CAD and put in a long passenger side shaft, but I'm concerned about being able to turn the truck. Also other route is to go with a locker and long shaft, but since I already bought this stuff, would like to see if possible to make it work. Thanks in advance for any advice.


With talking to some people could a person drill and tap the axle shaft end with a bolt so that shaft cant slide away like he say does?

When I built my Dana 60, I put the one-piece passenger axleshaft in, along with the Ford outer hub/spindle parts and Warn 35 spline lockout hubs. Has been holding up fine, but still is not the easiest to turn, even when hubs are unlocked. Hydraulic assist would be nice.

It's been a while since I had one apart but I think the spline engagement should be more 3/8ths anyway. How confident is he that his gear setup is correct?

Beleive easiest he could do is make a plug (piece of round stock) how ever long to go in between the axle shafts in the spool. That way hold the inner out to work with the cad.

In my experience a spool up front is really tough to manage and because there is no play locking in the collar doesn't work well. After a few years I found going to a solid axle with a good locker and stock carrier works the absolute best.

I've cracked the aftermarket yukon and detroit complete carriers but once I went back to the stock carrier with the "mini" locker I never had another issue.

I would say he needs to drive a bit and turn back and forth to get the CAD to engage, as the splines will need to line up for it to be pushed over. I had an ARB up front and rear. I would lock the rear as I drove on the track, and lock the front as I backed up to the sled, if the wheels were straight it wouldn't lock in. So I would saw back and forth and then it would lock(and you could feel it)

They way i understand him is the shaft slides away. Or it locks after first then gets moving and slides apart

Has he inspected the splines? Some of them will twist IIRC, so it will overcome the actuator.

Thanks Jeff for moving this post over here and getting added input from these guys. I messed with it some more and all splines looked good. If I had the truck jacked up and I lined up the splines, the actuator would pull the collar over no problem and would be engaged. But if they weren't, by the time they did become lined up, the inner axle would be pushed away.

But enough of that conversation.


With taking the input of everyone, I went and purchased a locker and the extended axle shaft for the right side. Just finished install of that yesterday and all is working as should be
