Had a loud rumbling noise on the car for the last couple of days. Happens in a straight line and when turning. At low speeds it's like a knock and at motorway speed it's making all kinds of rumbling noises. At one point it sounded like a plane taking off!
Jacked the front of the car up today to check it out. Both hub bearings are nice and tight (was hoping this would be source!). Bottom ball joints are fine. Inner & outer CV joints on both sides also feel fine.
With the wheels off the ground when spinning one wheel by hand (in 4th gear) there is a constant click from the box. In neuteral it's silent.
In gear with the engine running there is a noise, but difficult to tell exactly what it is over the diesel chatter!
There's little or no vibration coming through the car at any speed. N/S drive shaft seal is weeping a bit of oil, but not enough to drip off the car, so may just be residue.
Thinking either the diff or a bearing inside the box is on its way out.
Anyone got any other suggestions?
