My manual gearbox has a rumbling noise when it is in neutral however when the clutch is depressed the noise goes away. Would appreciate some advice on how to sort problem. thanks

I think removes the tyre both then check its gear box bearing noise or clutch plate bearing noise

clutch need to change

the lay shaft bearings inside the gearbox are worn,remove level plug and pump a grease gun full of grease into gearbox as this will help quieten it ,

What?! Really! The noise goes when the clutch pedal is depressed! So the noise goes when the release bearing (throw-out bearing) is engage? So how would that be a release bearing/clutch problem? If it didn't make a noise until the clutch pedal was depressed, it would be the release bearing! In other words its the input shaft bearing and/or counter shaft bearing in the gearbox. Stop giving people bad advice

manual ,thank heaven ,dont see many autos here in spain,right without driving car so i can hear it then it stands two possibilities ,when clutch is depressed you hear a noise like a grinding squel ,this is the thrust bearing ,if you hear a rumbling noise that disappears when clutch is depressed then this is lay shaft bearings ,Now also the problem can be the fingers on the clutch plate are worn and the bearing is pushing the clutch plate fingers down but if one or two are worn away then the thrust bearing is being pushed through the pressure plate ,either way a new clutch is need and as these vehicles are rear wheel drive they are not difficult to renew ,Just have to make yourself a clutch alignment tool from a broom handle .Dont be scared of it they are not that difficult to do just dirty and messy thats all the hardest part is aligning the clutch so the spigot shaft goes through easly and you dont have to struggle pushing the gearbox in

check oil level in gearbox

check brakes, check transaxle

needs a new clutch ,pressure plate dragging caused by worn springs

FORDS ARE OK if the noise u are hearing is going away when u press the clutch it sounds like it is comming from the gearbox. the gearbox stops turning wheh u hold the clutch in is the gearbox noisey when u dive it 1-2-3-4 this will let u know if the gearbox is worn
is oil level ok ? check it and transfere case

hope it helps let me know if u need more help

First check the oil level in the gearbox. The noise you hear sounds as though the pressure plate of the clutch is faulty. If every time you press the clutch pedel the noise goes away it points to the clutch. If this model has a manual clutch cable adjuster, try and adjust it to see if there is any inprovement.
