We took delivery of our gen 4 two Saturdays ago, the gear whine was the first thing I noticed - it's not a "bad bearing" whine, but it is noticeable, especially if you're coming from a second or third gen GV.
The gear whine on this vehicle was eventually traced (almost nine months after we took delivery) to insufficient lubricant in the transfer case - the vehicle was taken back to the dealership and a formal (written) complaint made, the case was drained & refilled, the gear whine is now reduced but still noticeable, and I am pushing to have the case replaced under warranty.
A few weeks back we were given an automatic transmission Jimny to "test drive" to compare the noise, (our Jimny has the manual transmission) and the automatic was significantly quieter, we're waiting on the dealership to 'ex-warehouse" a manual transmission Jimny to allow an "apples-to-apples" comparison.
I have considered installing additional sound damping material, but it's not going to happen until I've resolved the transfer case issue.
