I am in the process of replacing the ball joints and tie rods on my 300D and so far found that the tie rods were shot. The rubber was busted and there was no grease. The ball joints look pretty rough but the rubber was not busted and one even squirted grease out when I removed it. I had the "creaking" noise on the front drivers side when going over bumps. Should get it all back together this week and will let ya'll know if the "creak" is gone.
Take a good look at the rubber portion of your tie rods. If they are split try replacing the tie rods first - diyer type of job. I have a tie rod removal tool I would be willing to rent if you are interested.
