If you're just holding out til summer, just leave it. Not worth worrying about at all if you're trying to save money. It will be fine as is as long as you don't use 4wd very much, and especially with the freewheeling hubs.

You'd be surprised how long some people run split cv boots, even w/o freewheeling hubs and using 4wd occasionally. Sometimes years!
