Series 2a Gearbox Problem

Ok, so I managed to get my newly purchased S2a through its MOT with
only minor work, and I thought I was ready for a bit of gentle off
roading.

On its first trip out it performed very well and I thought all was
OK.... Until I decided that I'd had enough and tried to drive home.
As soon as I put the Landy back in to high range and got on to the road
I noticed a clonking noise coming from the gear box direction. I
stopped and checked to see if any damage was evident - none, checked
the oil levels in the gear and transfer box - OK. The funny thing is
that the noise still occurs when moving but out of gear, and yet it is
coming from the gear box area (but I suppose that the rear wheels still
turn the gear box when its out of gear). I managed to limp the 5 miles
home driving very gingerly because the noise definitely increased with
the revs.

Has anyone got any good suggestions for what could have gone wrong?
Possibly some stripped teeth?

Thanks

Three things jump to mind - the first is that you've chipped a tooth
on the rear diff, and it's only evident in high 4x2 drive - that
sounds a bit odd, but it has happened to me. The second, possibly
more likely, is that is the transfer box is not going "completely"
into high range - I've had this too. If you can't get it to sort
itself out by "working" the linkage, there's a cover on the
front of the transfer box that, when removed, reveals the selector
shafts - you should be able to see them reciprocate when moving the
red lever. Sometimes things get a bit gummed up, and some oil and
more working of the red lever will most often sort things out.
The third option is a collapsed UJ in a prop shaft - easy to
fix but makes some rather scary noises, and can be easily missed
if the props are checked with the wheels on the ground.

Check the hand brake is not binding, this used to happen every time I went
off road in my series the shoes get clogged up with mud and stick on and
this causes much weirdness in the transmission department...

Thanks for the ideas guys, I've got a few options there to keep me
busy! I'll let u know how i get on.

Has anyone got any good schematic diagrams or 'cutaway' pictures of the
series 2 gearbox and transfer box?

Yes - I can do bits from the workshop manual.

Is that e-mail address valid?

Good ones in the Workshop manual - the they are almost identical to the
Series 1, and the transfer case is almost identical to Series 3. If you
don't have the manual, there are some you can download it - Series 3 is on
landroverweb.com, Series 1 gearbox section
http://www.landrover.ee/est/varia/downloads/cars.htm,
and I'm sure a bit of a search would find Series 2.

For a cutaway or schematic the workshop manual is better - both have
exploded diagrams,but this may not be the best for understanding how it
works. The workshop manual also has explanatory diagrams.
