P38A Front Prop died!

Right, as they say, Necessity is the mother of invention.
Fingers crossed, I think my VC is working. I managed to do the attached video just now, is it working?

 
did you lift the front wheel off the floor, put in neutral and put socket and bar on the front wheel nut and try to turn it. You will feel a lot of resistance but it should turn slowly and consistently.there are a few vids on YouTube that will explain exactly what you looking for!
if you try this using the engine you run the risk of the abs correcting the traction control!!

...Last Saturday, luckily on a roundabout, my front drive-shaft decided to part ways with the transfer box. Made a bit of noise too...

... you would see I could not do that.

Why did you not check it with the prop off as advised?

Uh Wammers, prop? Uh, where? Look at the video again.
 
you cant check it without a prop dude! Uh!! It'll turn if is shagged or not!! If you dont have your prop then test it when you have one! Uh!!:confused::rolleyes:

Well Dude, by what has been said, the VC can be tested without the front prop in situ:

From what I understand you should be able to check out the VC anyway, apply the handbrake and climb under the vehicle with a large(ish) lever and see if you can rotate the front output shaft from the transfer case, it should be hard to turn but still should give, when the VC fails I believe it fails in the locked solid condition, so if it will not give at all, you know that there is the problem.

With 15 lb ft of torque applied to the front transfer box drive flange nut. VC should turn about 90 degrees in a minute...

Now as I tried to do what these two gentlemen suggested but failed due to location and situation I thought the next best thing would be to move the Beast forward and backwards a short way to see at least if the front flange from the TB was moving or not.
 
it will move! As I said, but without testing it by either method you are pi§§ing in the wind. If you cant test it, there's no real answer until you have the opportunity to do so..

Ah ok, so me bad. By being seized I thought that they meant that it would not even move, which in turn made sense of sorts to why the propshaft ripped itself off, if you get my gist. Especially as it was during very "gentle" manoeuvres, ie: gently pulling onto an empty roundabout... BANG.

Mind you, the UJs do seem more than likely to being the cause. If you look at the video you will see what remains of the sections of the UJ that fitted into the propshaft.

You should have used the method i suggested. Remove what remains of prop engine stopped gearbox in neutral and apply 15 lb ft to drive flange nut. Flange should turn 90 degrees in one minute. Flange should move independently of rest of transmission. What you show in video proves nothing. If you have replaced prop. Lift one front wheel and apply 53 lb ft to drive shaft nut. Wheel should rotate slowly. If it will not rotate VCU is seized. The direct on drive flange nut is the better test.

Ok carry on, but what you posted on video proves nothing. Horse to water and drink comes to mind. ;)

And as I said above (below)...

You are missing the point entirely. The video means nothing.

I think it is you Wammers that is missing my point, or at the very least you are either not reading or understanding what I have said! As I said "Ah ok, so me bad.

I will say this only once more then you can get on with what you want to. The drive flange will ALWAYS move as in your video. The important point is does the VCU slip as it is supposed to do. If it doesn't your new prop or maybe your diff won't last long. You don't appear to have checked it so you don't know. I am trying to give you good advice you seem not to want it.

I know you are and I appreciate it. All I have said is that due to the location and situation I am in at the moment I have not been able to do what you and a few others have advised. On top of that I have also said that, until only yesterday, I was misunderstanding the comment of the VCU being "seized", hence the useless video.
