Hi to All

I hope your all well?
im after some advice please.
disco3 (LR3) etc.
ZF6 HP 26 box, starting lightly clonking from D to R and R to D.
whine like 3 stage whir whir whir in 1st & 2 nd gears, can’t hear it in any other but could be due to road
noise.
sounds like a rotary noise.
rumble in 5 th and 6 th aswell as faint pitch noise.
sound like a bearing out.
front diff metal flakes on plug but not massive amounts.
trans case clear.
rear diff not changed for 8000,00 miles but was clear when changed.
engine sounding under more pressure than should be, a bit like a hair dryer but only when under
pressure sound fine with no gas down.
general rumble but quite quiet around 55 to 65 mph but clears up over 70 mph.

anyone with some 1st hand experience please pass on your thoughts.
im in Uk or possibly Eu, were still not sure at the moment, so if anyone is in this country in Hampshire
please get in touch, if not just advice and thoughts from you guys would be welcomed.
oh yeh advice on the discovery not the E.U. 😄
