New Front Halfshaft. Is it Fully Inserted?
Good day, Disco3 experts.
I replaced my front halfshaft (left side) this weekend. From what I've read on this forum, the "special" Land Rover tool for re-inserting the halfshaft isn't necessary. Just be careful to avoid pinching the oil seal when re-inserting, and torquing the hub retaining nut will ensure that it's fully seated.
When inserting, lined it up (straight), gave it a good smooth shove, and tapped on the hub end with a hammer for good measure. I can't pull it out, so I assume that the circlip is engaged.
But the flange seems further from the differential than I remember on the old one. See photo of the new halfshaft where it enters the differential.
I still have to torque the hub nut (need brakes back on to do that). But before putting the brakes on, I wanted to check the collective wisdom of this community to see if it looks OK.

No, you need to push it further in.
When you Start pushing the Halfshaft in you can feel a little resistance. This is the c–clip before it gets settled in the groove.

Thanks Achim, for confirming my suspicions.
I don't think I can muscle it in any further by just pushing.
Is it just a matter of tightening the hub nut? I'm trying to imagine the forces created when I start tightening the hub nut. Do you think that will be sufficient? I could put the rotor back on and use that trick of putting a rod into a slot in the top to keep the axle from moving when I tighten the hub nut.
Or should I have the halfshaft fully inserted before proceeding with putting the other pieces back? I could devise some mechanical advantage to put something over the cup and pull it in (towards the opposite side of the vehicle).

I just overhauled my Front diff. My Drive shaft did Not want to Go in.
With Little force I moved it back and forth by just a centimeter or 2. than it snapped.
It really Dosen‘t Need much force.
May the force be with you Achim

Ahh, sometimes you just have to believe. As suggested, I just needed to pull it out a bit and re-insert it with a bit more vigor. This is the way it's supposed to look:
for the record tightening the hub nut will have no effect in the inner half shaft CV seating properly in the diff

Hi Shane. Thanks. That's why it's good to look at the physical things rather than in the mind's eye. When I looked at the hub nut, I saw that tightening would more likely pull the shaft out further (if it weren't isolated from the differential end, which as you say is the case).
So I didn't pursue the hub nut tightening. In fact removed it and the hub bearing assembly to allow me to pull out and then re-insert the halfshaft with more vigor.

@ DVD
looks much better than before.
But the outer shell of the drive shaft end should be closer to the diff housing. It is supposed to protect the diff seal (TZB500050) from dirt and mechanical damage.
I'll try to take a picture of mine later today.Achim

That inner CV is designed to slide in and out as thats what happens slightly during the suspension travel.
