Where to adjust Mercedes W124 steering free play?

To adjust the steering free play on a Mercedes W124, locate the steering box, which is typically found near the firewall on the driver's side. There is an adjustment screw on the top of the steering box; turn it clockwise to reduce free play and counterclockwise to increase it. Make small adjustments and test the steering feel after each adjustment to ensure it meets your preference. Always be cautious to avoid over-tightening, as this can lead to steering stiffness and increased wear.
