Gooday all. Could not find anything on search but have a problem with my 2003 TD5. Changed my front prop shaft bearings a couple of weeks ago and thought I would have a visual just for peace of mind. Somehow I ended up turning the front wheels in Park whilst on stands. Both front wheels turn in opposite directions as I believe is correct, but the prop shaft remains stationary. There has not been any phantom noises and no metal when I drained the oil several months ago. Nothing to make me feel there was a problem. Thought it may be a loose rear flange but believe the flange is splined onto input shaft. My only thought is that the input shaft has sheared inside diff. Has anybody had a similar experience.

If both front wheels turn, in opposite directions, AT the SAME TIME while the prop is stationary.
That is normal.
:):):)
Drop one wheel onto the floor, put it in neutral and see if turning the raised wheel moves the propshaft. If it doesn't then you do have a problem. ;)
 
Just put the transfer box differential into lock and prop won’t turn, because its locked.
 
Thanks for your prompt replies. The front wheels do turn opposite ways together when jacked up. Tomorrow I will jack one side up and see if that wheel drives the prop shaft. Thought that as diff is mechanically locked the output to transfer box is always connected. Should have paid more attention at school in the sixties I think. Many thanks.
 
In a D2 with no diff lock engaged, any breakage of halfshafts etc will cause no drive at all. So if it drives, its in 4wd
 
I think some people find it a bit difficult to visualise how a centre diff lock works and how to test it!
However, what is essential to know is that if driving off road or on any slippery surfaces, i.e green laning, diff lock MUST be engaged to prevent damage. If not engaged one or more wheels can spin like mad and that does the diffs no good at all.
This from Ashcroft on another thread, a while back. ;)

That's just another example of landie madness.. wait.. you took it off road!? You spun a wheel for a few seconds!? <Whistles between teeth> that's your problem right there
 
Gooday all. Thanks for your replies. Helped me understand my drive system. Have been guilty of just thinking the diff speeds up or down inner and outer wheels by magic and have never fully understood the working of the diff. It just does the job. I have now more understanding due to your replies and youtube diff vids. Ashcroft rebuild diff video in particular. Until the next time....thx

Thanks.
It is nice to be thanked!:):):)
(Explaining how a diff works without one open in front of you is a bit like trying to explain the offside rule to some peeps.)
I think the Austin Champ had a solid rear axle and just lived with tyre scrub, but I may be wrong!
