R380 new noise

On highway today, tranny started whining much louder than usual and under power would tap under load. Every gear except 4th, which was nice and quiet. I'm suspecting a bad bearing. Gear changes all normal. Just dropped off at British4x4 in Durham, and I'm suspecting I need an overhaul which they outsource. Is this a clear cut issue or could it be something else? I'm waiting to hear their thoughts. They ship trannies out to Southwest in TX.

A rebuilt unit from Ashcroft is about 1500 on your doorstep, or at least really close by.

Seems like a bearing. Since it is not in 4th (which is direct drive) something on the lay shaft I would guess.

Please let me know what they say. I'm experiencing the exact same symptoms right now.
Also no noise in 4th gear.
Shifts fine.

Well there is a lot of writing but under noise diagnostic procedure. #4 says


4. If there is a gear noise issue from the manual gearbox, it will not be apparent in all gears. If there is a gear or bearing issue on the lays haft, it will be mainly audible in 1st, 2nd 3rd and 5th gears. The excessive noise will become much reduced or no longer audible in 4th gear.

I had the same sounds. They developed into an intermittet dry grating sound the finally after a drive over the Rockies, into a godawful scheeching. After towing it back home a stipdown showed the intermediade taper roller had failed and had spun the outer raceway in the aluminium housing. see attachment.

My solution was to go Ashworth for around $1700 landed with 5 day delivery. Great service, great delivery and no messing with a core. Best was that it was built to the latest (last)suffix with the upgraded bearings and cast iron race retainer. Have around 10k miles on it without issue - and mostly trips over the rockies to offroading trails.

The only fiddly bit was resetting the gear lever hairpin springs that line up the lever with 3rd at rest

Dave Ashcroft actually answers emails himself and reliably answers any questions - even the stoopid ones -overnight.

My decision was determined by asking myself which was the best option. Buy a rebuildable core from the Rover hive and do it myself, buy one from someone who is an expert in the field with a stellar rep and builds them day in and day out, or have someone rebuild it for me here in the USA, or buy one from one of the vendors?
For what it was going to cost, Ashcroft beat every other option by a mile and then some. I mean really who would you trust? Dave Ashcroft or some unknown person?

It's about the same effort as the Jeep. Maybe a half a day to get the old one out and another half a day to get the new one in. I'd say it will eat an entire weekend if you haven't done one for a while. While you are in there, replace the motor and transmission mounts, clutch and bearing.

Here is mine. There is also an LT230 kit and clutch stuff in there:

You guys are going about this all wrong. Just buy Jeff a plane ticket and let him do it. Just make sure you have lots of coffee and beer. In all seriousness as a person who doesn't normally do this type of work I will give you a tiny bit of advice.

Have a highlift to separate the frame so the tranny cross member will come out easily.
Take the floor boards out so you have room to work.
When dropping the tranny make sure you have a tall floor jack and lots of things to support the tranny. It's heavy. Having friends to guide it down helps.
mark your drive shaft so you can put it back in the same way you took it out.
Make sure you have misc crap around. I broke a couple exhaust studds when dropping the y pipe. I also realized my seals from the y pipe to the manifolds needed to be replaced.

I think that is everything I can add. Did I mention beer and coffee?
