Clutch or gearbox?

Hi from Tarifa, Spain - I'm new with the Defender, so please excuse some "stupid" questions.
My actual problem shows as follows:
Motor runs, gear is in, foot of the clutch -> no movement (speedometer shows speed)
Same as above, but with handbrake slightly engaged -> the baby moves
My questions: does that sound like gearbox or clutch to you? where to start to rip the babe into parts?
Thanks a lot for your hints in advance!

Ralf, welcome to the forums.

This sounds like a broken rear axle. By applying the hand break you are doing the equivalent of engaging a rear locker. The good news this is usually easy to find and fix. Engage the center diff lock and the truck should drive in front wheel drive.

Or just undo the ring bolts at the flange and pull out the axle shaft. The broken one will be obvious. You'll need to do this to permanently fix the problem of course.

hth,
charles

Broken axle or cv. If you put it in differential lock (pull lever to the left) does it move?

Thanks, but why is there no traction at all, at least the fwd wheels should do something, right? Besides: if I apply the hand break completely the car stops. (I'll check the axles as well) Any other idea?

Did you engage the center diff lock? Without it the front doesn't get power if the rear driveshaft spins.

Since the speedometer is reading, it means the rear driveshaft is spinning away with no resistance which means a broken axle.

With a broken axle, the entire drive train wants to follow the path of least resistance; the broken axle. So inside the diff the broken off stub is spinning away, completely disconnected from the tire. Since all that twist is going to that corner, none goes to the front or anywhere else. If as Charles says, you lock the center differential, then the power that was going nowhere will go to the front axle.
You should move with the center differential locked.
This is pretty much true of any 4 wheel drive vehicle with all the time 4wd. On vehicles that require a lever to engage 4wd, like early Jeeps and Land Rovers, you would still go with a broken axle because there is no center differential.

Oh and when you see it's a broken rear axle, start with the short side - they usually break first.

All the same with or without diff lock, no movement: shaft to the aft diff is spinning.
So either both axles broken or the diff is f****?

If your center diff light comes on and the front diff is not spinning then I suspect you have a transfer case issue. But you need to verify the center diff is locked. You can try roll the vehicle a bit to get it to engage.

Pulling the rear axles is easy so do that before messing with the transfer case though!

Both axles OK.
When I took out the short one, there was a strange noise like something fell off from the inside of the diff.
Guess I'll open it now - any advise?

It should still move under it's own power with the center differential locked. So something doesn't add up. Did you see if the front driveshaft spins as well?

Did you take pictures of the axles?

Multiple Issues ???

Could be wrong, but it sounds to me like you have 2 different drivetrain problems.
I think you have a failed diff bearing that is making the pinion flange very difficult to turn in unison with a broken axle of CV joint.

Put it in diff lock and give it some revs and you should move, but better still start by getting underneath and seeing if the diff flanges have some movement. With everything connected, you should have about 1/4" of free play backlash movement. My guess on of the diff flanges will be stiff with no free play and that's where you start tearing down the assembly.

Raif,
Are you certain your diff lock is engaging ? When you shift the transfer case knob over to the left side of the H shaped shift patern does an orange light illuminate on the dash ? It is possible that if the light is coming on that your truck has been driven on pavement with the center diff locked and the cross pin is broken which may have also signifigantly hurt your rear diff although this usually takes out a front cv joint. If you heard something drop when you pulled and axle shaft I would definately dissasemble the axle assembly

The Diff is entirely f* the pin is broken into 3 pieces... the holes for the pin are f* as well, all gears destroyed...
I've contacted a guy nearby who sales 2nd hand parts to check if he has a 54 dent type diff in his store.
Anyhow there is another worry: shouldn't the front shaft move when diff lock engaged? (It doesn't). Do not worry about any indication lights, as the cabling is a nightmare too...
So first I'll exchange the aft diff now.
Once done that, with the babe on the blocks, the fwd shaft should spin as well right?

As I read in a German newspaper lately: If you want ensure, being able to use all of your tools, never having the need to drive, than get yourself a defender... feeling close to that :-)

Any idea about a fair price for a used diff? (complete)

Hard to say over there, but this side the pond we trade them regularly for $75-150 depending on mileage.
They fit nicely in a 5 gallon bucket for transport/ shipment. Being a 98 90 your truck can use a diff from any 90-99 disco 1 if that helps, doesn't have to come from a defender.
