hi .let me tell you a story, it started with a humming noise so i changed the near side wheel bearing /hub. no luck so i checked the oil in the diffs all ok the brake pads are ok so i,m at a loss what to do next. there is however a oil leak from the gear box so i checked the oil level and it came out fast is that the norm? any help please arv

The gearbox oil is ATF so very thin and will come out fast when you drain it. Even the transfer box oil comes out pretty quick ( well, mine did!) Did you mean the oil came out when you checked the oil level? Make sure you are on level ground. If it comes out its too full, check to see why. Is it overfilled? Check both boxes, make sure they are at the right level.
Have you checked your tyres? I had a couple of cars that started getting a humming noise that increased with road speed. Checked wheel bearings brakes etc, then found it was uneven wear on the tyre. Easy to see, just look at the surface of the tyre from low down behind the tyres and see if the tread looks uneven. My tyres were a sort of block tread and I could see the blocks worn at one end on all of them, this caused the humming noise. New tyre of a different pattern fixed it.
As V8 Disco says, a little more info on your car and the full symptoms would help.

NEVER remove the fill plug on a D2 auto without the engine running, as you will loose a lot of fluid.
You may well have to top it up now, unless you intend to drain and replace the ATF fluid

Of course, it could be a manual, or did I miss something. As the first reply said, more detail please, about the car and the noise.

So, did you check the tyres?
hi i have 3 cooper snowcat tyres on and 1 goodyear eagle Ls2 its been on a while now (9 months prob ) and i have changed it from the front to the rear and now to the opposite side but the noise is the same .i think im more worred about the gear box now unless thats the cause of it arv

How long have you had the noise? Just asking cos if you have only had the tyres on for 9 months it could be something to do with them

Re checking the oil level on a Disco TD5 auto, there is a specific procedure which needs to be followed to get an accurate reading:
1. Starting with the vehicle on level ground and a cold engine, start the engine;
2. Cycle through all gear lever positions leaving in each one 2-3sec to take up drive, then put back into N and with the transfer box select neutral (this is a safety issue for whilst you are under the car);
3. With the engine still running - Now get under the car, have a catch tank ready and start to undo the fill/level plug on the front face of the autobox, just above two metal oil pipes.
4. Once removed, there should be a small trail of oil flowing out of the hole, this indicates the correct level. If no oil comes out it needs topping up with Dexron III autobox oil until it starts to flow back out.
Replace the fill/level plug and you have completed your mission

When I look for a fault on anything, I always look at the most obvious / cheapest solution, because sometimes the solution is simple. I use a process of elimination and get the easy stuff out of the way first.
What makes you think its the gearbox?
What speed does the humming start and is it metallic sounding in any way?
My money is still on the tyres because I have had this noise before and it is quite a common problem. ( google humming tyres!) but of course, I'm a bloke so could be wrong!
Changing one tyre around to different wheels will not eliminate that tyre. You need to inspect the tyres for uneven wear then swap each one with a good one ( spare?)
Or, if the humming comes in at a lowish speed, can you get to a smooth grassy / sandy area that will let you do the same speed when you normally hear the humming.
If the hum goes, it could be the tyres, but I think you should check that first.
If the noise is still there, then look at uj"s, propshaft balance ( take one off and drive again using diff lock) Check it while driving in low range ( is it still a road speed hum?). Check all the wheel bearings.
Only when you have checked all these should you suspect the gearbox ( unless theres a real reason you suspected the gearbox all along.)
Try simple fixes first, you never know, it could just be something easy to sort out.

I did put the spare on and gave it a run and the noise is still there. its on the near side front where i had the bearing done .you can hear it more clearly when slowing up say for a junction before i start to brake and seems to decrease with the speed of the car thanks

Why not with the most obvious. Jack up front nearside and run engine in high gear. Then try with wheel off. This will isolate if a wheel or tyre problem. Then look where the noise is coming from but don't get too close to the prop shaft. You may get a few clues following this process.
I don't know about D2s' but I assume permanent 4 wheel drive.

Have you checked you brake calipers? Mine was a little noisy recenty and turned out to be a sticky piston and very worn pad although other 3 pads were only half worn
