Other than doing a front end and power train lube every 3k miles, I just have the wife move the steering wheel back and forth in short cycles while I'm under the front end inspecting for excessive play. I check for play in the steering box, pitman arm, tie rod ends...everything from the steering box to the wheel ends. It helps when checking the king pins if you have a bottle jack and jack stands so you can get at least one of the tires off the ground so any excessive play will show itself. Also, make sure all dust boots are in place and in good shape so your grease stays uncontaminated.
I'd also recommend you have a front end alignment done just to make sure you running with the correct settings that can effect handling and excessive tire wear...well, unless the PO had this done and you know what you've got. Bob
