How did you verify the flanges and birfs? There are other things that can go wrong, like a grenaded diff, axle, or birfield, but eliminate the simple stuff first. Might be a good idea to start a new thread, if in fact your flanges/birfs are actually not the issue. If you need a method for verification- pull the dust caps off the hubs so you can see the axle stub ends. Have someone start the truck and put it in gear, hold the brakes, rev the motor or whatever it takes to get noise, make sure one of the axle stubs isn't spinning in the flange.
If you do this test and neither of the axle stub ends are spinning in the flange, does the truck rev up with the truck stationary? If it does, something's broken in one of the axles. Chase the noise to figure out which axle.
All this is assuming you have exactly the same symptoms as the OP.

I have same problem on my 105 series petrol 4.5L which is the same as 80s series I've heard, it works in low range but not in high range, if i turn on diff lockers it works on H range, unsure if i can can drive in H range with lockers on
You shouldn't drive it on pavement with lockers. You have likely broken something in the front axle, such as the drive flange (most likely) or a birf or axle shaft. If you must drive it, put it in low range, which will engage the center diff locker (assuming you have one in the 105), then remove the locker fuse and put it back in high range. Without the fuse the CDL won't disengage. But you should find out exactly what the issue is- a drive flange is no big deal, a broken axle or birfield could lead to other issues if you keep driving it.
Yea i just gotta drive it 2 kms to mechanic
