Converting this axle to full floating to remedy this problem isn't cost effective for your application.
I disagree steve, there would be virtually no cost in doing it for a trailer. If you've still got the front half of the vitara you could use those hubs. Given it's only a trailer you'd make your own adapters out of flat plate and weld them on as concentricity isn't critical. Then you wouldn't be wasting energy turning the diff, wont need to keep oil in it and wont be lugging around that weight for no reason.
You could also remove the crownwheel from the diff centre. You'l still need to keep oil in it but then you wont be spinning the pinion around for no reason. Lots of farm trailers are like this or have the pinion removed and the hole capped. Of course most farm trailers using a rear diff are built out of trucks with fully floating axles. Generally the axles and diff centre are removed and sold off and the openings are capped.
