Transfer box woes

I know it can take some time to track down an odd noise, plenty of places for them to come from in a landy drive system. Try running without front prop and see if it goes away, you will then know if worth getting into front housing.

^^^ Wot he said - take props off, one at a time, and see where that leads you

If you're fitting new output seals, then, for the minimal extra cost, I'd fit new output flanges too - IME, the br*part ones are fine .....

Had a better look today and thanks to the cross drilled input gear there's no perceptible wear on the input shaft or the gear itself. I did notice however that on turning the gear I get very different reactions at the front versus the rear. The smallest movement of the input gear directly corresponds to movement from the front output flange, whereas from the back I can rotate the drum and get very little to no movement from the gear, which leads me to believe that I'd be better off replacing the rear output shaft and bearing? Took as best pics and videos as I could get so hopefully you can see. I'm wondering if this is a bit source of my clunk

Well that wont help. Front drive flanges are excessively worn, I could turn one of the wheels almost halfway around before I saw any movement in the propshaft. Turning just the halfshaft on its own is fine there's a very small amount of free play but nothing I'm worried about. New drive flanges are cheap happy with that lol

Thought I'd got to a big cause of the problem in the form of a snapped halfshaft on the front left as turning the wheel did nothing to the prop. I've taken it all apart however and it's absolutely fine, no issues with the halfshaft or cv joint. What I have noticed however is that now neither the left or the right half shaft will turn the prop when turned independently. I can rotate the right halfshaft completely freely from the prop whilst rotating the prop with my other hand. I'm going to guess that something inside my front diff has given up if that's the case?

What happens when you turn a half shaft when the other side is also disconnected is the drive goes the easy way through the diff and the shaft on the other side rotates in reverse and the prop does not turn. It is just what a diff does. If anything in the axle was broken there would be no drive.

Yeah that was just me being an idiot. All is well although stripping the hub down wasn't a waste of time as it badly needs a rebuild. CV joint is still good but the swivel ball, seal, swivel pins and bearings have all seen better days. That'll be another trip to ebay then...
