if there the same ones from a year ago, I'd say thats pretty good life if you've been driving your truck frequently. A lot of racers I know will change their outdrives on their car after only 2-3 months of weekly club racing. And I have seen the outdrives they use, theres only a tiny groove forming and they toss them.

The center on mine have a tiny groove, but nothing major yet. Front and rear, so far so good.
