the front diff is part of the gearbox and the diff/gearbox oil is the same-there is a dipstick on the offside of the box near the bellhousing.
Top of the gearbox diff housing
not enough oil usually
diff sizes for front and rear.
oil for what rear axle ,ayc unit,gearbox,transfer box ,front diff or engineo or the brake fluid
It runs from the clocks in the dash all the way to the gearbox where it screws into the box at the rear just above the diff housing.
Your tires will wear faster, and you will put pointless strain on your drive shafts. Depending on what type of diff you have that too might wear faster. The car will handle poorer during sharp corners on good surfaces.
Sounds like the diff in the gearbox is goind and will need the whole gearbox replacing soon before it fails completely.
Just normal 4x4 driving won't damage anything. If you drive for a long distance with the diff lock on though you could damage tyres and at high speed could be dangerous,
If you check the gearbox code on thisbox and find its F5M41 then the drain plug will be on the diff case..usually its quite a large one 24/to 34mm in size ..
Yes you can, as long as you replace all four tires. Having different sizes tires on the vehicle will ruin the diff as the car believes it is constantly cornering, thus wearing either side at a different rate.
The Tdci's gearbox is supposedly "filled for life" and hence does not have a drain plug. The gearbox oil will drain out of the diff if you should ever need to change a drive-shaft. The gearbox oil level can be checked and topped up by taking the rectangular plastic cover off the front of the box (it's only clipped on to cover the clutch lever), then use a hex wrench (Allen key) to take out the black filler plug and squirt some 75w/90 in until it starts to dribble out.
