I have just had a new mainshaft put in my LT77, at the same time I had the LT-230 changed (second hand but was nice a tight with no play), when I now drive it I get a high pitched whining noise coming from around that area, is this normal, does the mainshaft have to bed in?
-
that will be the transfer box bearings whining at a guess, just have to put up with it, or do what i did and buy a new one. you will eventually cuz it drives you crazy.

IIRC LT230s run on EP90, if so try some oil stabiliser from Lucas oils. I put some in my B-W and it stopped some of the rumbling I was hearing, what was really impressive is the rumbling turned out to be the front diff, the oil was stopping the noise being transmitted through the drivetrain.

Saw a demo of that at a local motor factors and I was debating getting some to shut the Zooks gearbox up. I think I just might now.

The noise now seems to go when the clutch is in, Its a new clutch and thrust bearing about 500 miles ago, does the T-box stop rotating once the clutch is depressed?

THAT WILL BE THE BEARING IN DE CLUTCH THEN, MINE did that with a new one in too, very anoying, but luckily the new engine i had fittedhad to come out and they stuck another new one on and its cured it.

Everything stops from the clutch backwards, provided the car isn't moving.
It could well be the thrust bearing, perhaps it's not fully lined up yet, or perhaps it's duff.
