I just got a one-owner 1998 C230 with 133,000 miles. I noticed that the steering seemed a little "loose" and followed ruts in the road. I jacked up the front end and noticed that when grabbing the wheel at 3 and 9 o'clock I got quite a bit of play, which was from the inner joints of the center/drag link. I replaced that and this play is now gone. Also the toe in was about zero so I set that also. However, I also noticed that when grabbing the wheel at 12 and 6 o'clock there was a smaller amount of play that I believe is from the wheel bearings. I checked the end play and found it at the high limit of 8 ten thousandths so I reduced it to 5 1/10000" by only about a 1/2 degree tightening of the lock nut. I thought it would take about 2 degrees considering the pitch of the threads but it didn't. It still wiggles the same as far as I can tell and the main symptom that I still have is oversteer: When I go onto a freeway on ramp for example, as I steer into the turn, it oversteers and I must let up on the wheel. My last car was a 1987 Toyota Supra and it had none of this, and it had 260,000 miles. Any opinions on the wiggle in the wheel and if new bearings will help, and if this might get rid of the oversteer?

Thanks,
Mike
