4x4 selector-shaft box suddenly rattling/make noise in 2H
I've had to use 4x4 more than usual in town recently due to snow volume (so in and out of 4WD). 4x4 worked fine, 1st time shifting into 4WD was a little 'stiff' as it has been quite a while since I've had to use it. Now that roads are clear and I'm back in 2WD (hubs on free), the selector box is making a constant fairly loud rattling noise. Stops/lessens if I hold it the selector gear stick ...

What type of vehicle is this? I'm assuming you have a part time transfer case with the 4h,4l and 2h selector switch. Without knowing the vehicle I can't be certain, but the problem you are describing sounds like the Encoder Motor on your transfer case has gone bad. Can you hear any noise when you try to select a gear range?
hi this sounds like to me you might have a loose baffel in the box, the reason why the sound dissapates when you get to a certain speed is because the baffel is pushed up or down due to the pressure when you slow down the pressure then releases the baffel and it starts rattling again, you might also have a broken clamp on your exhaust or even a missing rubber bush check these out first...good luck
They had a issue with the steering column slip-shaft making noise. You can tell if thats the source of the noise by grabing the shaft above the steering box and moving sideways-back and forth, if you can hear it rattleing and feels loose it's most likely the cause. The only way to stop it is to replace the shaft with a up-graded part from GM.
This drove everybody crazy for a while untill they found the problem and redesigned the shaft.
Without looking at the vehicle and driving it myself, I would say your guess is a pretty good one. Usually that can be caused by chopped or dry tires. There could be other causes too like drive shaft ujoints, cv shaft going bad(if yours is 4x4), wheel bearings too.
I believe that Mitsubishi has one of the best and easiest 4X4 selector systems on the Pajero/ Montero. Just below the gear shifter lever is the 4X4 mode selector. A lever like the gear shifter that works in a up, down movement. On your dash board you will notice a sort of axle, chassis diagram in green light. In normal 2WD or 2H mode the lever is set all the way back and on the dash only the rear wheels a lite up in green light on the axle, chassis diagram. This is for normal driving on the highway and smooth roads of dry dirt roads. Pushing the lever up wards while moving at crawling speed will engage the light 4X4 mode which is 4H for when the driving gets a little slippery. All 4 wheels on the axle/ chassis diagram will be lite green. Shifting the lever from the 4H position to the left and upwards will engage the 4HLc mode for 4X4 on sand and deep snow. This will also engage the central diff lock which will show on the axle/ chassis diagram on the dash board with the center box also lite up. Further up from the 4HLc mode and while pushing down on the 4X4 lever push it to the top most position, but only do this when at a stand still with your foot on the brake pedal. This will engage the 4LLc mode with 4X4 and central diff lock on for when driving gets sweaty on thick mud up and incline. To disengage this mode stop, foot on break put it in P and then pull down the lever to one of the lower settings.
4 wheel drive trucks make this sound alot im guessing its a manual shift so i would saw that the meshing is more of a grinding instead so i would have the transmission rebuilt to fix the problem or just see if the rings inside the trans. is missing the tooths on it :)
