Hey all,
car: 90 defender 1993 200tdi 5 speed
After a recent journey down the motorway the gearbox/transferbox started to whine quite a lot and there was a fair bit of vibration.
Fearing the worst I left the motorway and used the back roads for the rest of the journey. The lower speeds stopped the whine but a new vibration/clonk has started mostly above 40mph, but now even at lower speeds.
After a couple of weeks and maybe 1000km more driving the problem is getting worse. Yesterday had to drive over the mountain and back, on the return climb the roatational lumpy feeling/inaudible clock was happening more and more and at lower speeds too. spose the total journey was about 80km with around 2000m of climbing in altitude. long enough to get the oils to full temp etc.
Just checked the diff and transferbox oil levels and both the rear diff and the transfer box were low by about 200/500ml respectively. the rear diff is leaking at the wheel bearing end and the parts are turning up this week to sort that out.
The transferbox looks to be leaking between the first part after the gearbox and the main part of the transferbox. There is a join in the case where it seems to be leaking from.
Refilling both made no difference to the clonk (which has sped up enough to be more of a vibration now)
Couldn't check the gearbox level as didn't have any spanners to hand. front diff was fine.
The props seem sturdy and mounted well, a little side to side movement in the front one but not very much.
The vibration is still there a little with the clutched pressed and freewheeling, but only a tiny bit. It seems more connected to engine speed as it will do it in high revs at lower speeds. going uphill makes it show up more, spose as there is more load on the drive line.
So my fear is that the oil has leaked out of the transferbox, run the car without enough oil at speed and done damage to the internals.
It's now off the road as I feel it's being damaged every time it moves.
What do you guys think might be at fault?
Are there things that can be checked to confirm damage or good parts?
Thanks for reading.
