Did you struggle getting the collar onto the inner shaft? It seems like it wants to line up, but won’t slide onto the inner shaft. I guess it’s gotta be absolutely perfect to slide on
I didn't. Don't you have the FAD open at this point? You should be able to just put the collar on the end of the inner shaft, far enough that it won't fall while you slide the outer in. Like 2 seconds with your hand.
Yeah, that’s all correct. But for some reason, I was struggling getting the collar to slide onto the inner but I finally got it. Does the inner and outer shaft need to be touching or is this gap ok? Seems like the axle shaft can’t go in any further but I see a slight gap still.
So I can't say I looked at the width of the gap -- but it makes sense that the two can't touch because you need them to not rub when disconnected -- it's the sliding of the collar across both axles that locks them to have 4WD.Yeah, that’s all correct.

Appreciate all the help! Damn feels good to do this stuff on your own. (With a little help from the pros). Going to button up this side and get started on the driver. Who knew a set of ball joints would be a 4 day job……
Interesting engineering decision on behalf of Jeep/Dana, assume it's to get a little oil to the intermediate shaft bearing? Only thing I can think of that would like some lube in there. Doubt much gets up towards the collar.
My collar was lightly coated in oil when I removed it. No way you want to slide a dry collar back and forth. Remember when you shift on the fly into 4hi at up to 55 mph, the inner shaft has been spinning backwards because of the spider gears. The outer shaft is spinning forwards at full speed, and the collar is meshing the two.
Don’t worry, it gets plenty of oil, lol….this the rear diff but you can see how fast the oil gets everywhere soon as the ring gear gets going
I guess I always figured the collar and bearings were well out of the way of the ring gear splash given they weren't super close to the ring gear and that most of the work was done by the bevel on the collar and the hardness of the material for the shafts and collar. TBH, even with a light coat of gear oil, not wild about the FAD mashing things together at 55. If I was doing a lot of that I'd look into a FAD delete, personally.
I'm just so much more used to thinking of the gear oil slinging being for the bearings in the case I don't even think of the FAD. Feels so far away from the diff, breaks my head a bit to think of the oil slinging making it that far laterally lol
I’ve got a front locker. FAD is closed back up already. This is on the driver’s side too. Which I thought was a simple pull out, put back in and no collar to worry about.
This doesn’t happen in a vacuum, when you pull the lever back you are also engaging the front driveshaft which will stop the spiders and inner shaft from spinning backwards. I bet there is a delay in the FAD engagement too.
I'm not sure about the front lockers in a JL making that noise. Probably it was there before and you didn't notice. Perhaps someone else with a front locker can chime in.
I’m going to pull the axle shaft back out tomorrow morning and try reseating it. I don’t know what else could be the issue right now. Don’t have the energy to keep troubleshooting tonight. I’ll check back in tomorrow. Thanks again for the help.
