My new to me 1999 Defender 300TDi manual van is making a very nasty noise from I think the transfer box.
I've had it about a month and in that time there's been a very intermittent screeching noise, only lasts a second. Sounds like gearbox area? I have replaced the front propshaft front UJ and thats all I've done to it.
Today driving along at 60mph the screeching noise appears and this it doesn't stop. Being an ex two stroke racer I jumped on the clutch, made not difference, could definitely feel something seizing up, didn't lock though.
I pulled over and looked underneath, all the familiar oil leeks but propshafts where their supposed to be etc.
Messed about with Hi Lo and difflock all drives.
I got up the courage to limp home and the noise sounds like a seized/damaged bearing, dip the clutch put it in neutral and noise still the same.
I got it home and had look again underneath. Back prop had normal smooth backlash, but the front prop had notchy/stiffness in the backlash.
I haven't had time to jack it or get the front prop off yet. I did feel both UJ's on the front prop, neither were hot.
One other thing I did was put the Hi/Lo box into neutral and with the engine running went through all the gears, no sound at all. So I think I can say the gearbox is not the problem, must be transfer box/propshafts/axles etc.
So I think it's a bearing in the transfer box. If it's an output shaft bearing can I do this without taking the while gearbox out??
Many thanks
