You know the Cent better than me, but can I ask what oil you are using in the transmission and final drives?
A conversation in the Carrier Forum reveals that the Cent was specified to use OC600 oil in the transmission, a heavy viscous oil:

Mac's Auto sell a similar heavy gear oil (disclaimer: NOT stated to be equivalent to OC600), and they state that it's use was specified "in differentials because full floating rear axles were not in general use, and allowance had to be made
in the seals to allow the axle to move up and down as far as a quarter inch. To prevent the oil from leaking at the wheels the lubricant was made to cling to the gears. The same principle applies to transmissions and steering boxes.
The main causes of oil leaking at the rear wheels are worn seals or bearings, but over filling and/or
using a lighter weight lubricant than recommended can also cause leaks."

If you say removing the Transmission is an easy job, then go ahead, but it might be even easier to confirm the appropriate viscosity of oil is not the cause of the leaks.
