Not a whole lot that the dealership will replace for 'common warranty repair' items until they break, for example they are not going to replace a window regulator unless yours is busted even though its a common problem.

You could ask them to check suspension components - boots, sway bars, bushings, CV joints etc.
I would make sure that all of your 'free' fluid changes/maintenance items have been performed per maintenance schedule - brake fluid, coolant, oil etc.
