BMW E46 Steering Rack Description:

The BMW E46 steering rack is a precision-engineered hydraulic power steering assembly designed to deliver responsive and accurate handling for the 3-Series (1998–2006). It features a rack-and-pinion mechanism with an integrated power assist system, using pressurized fluid from the power steering pump to reduce steering effort.

Key details:

• Type: Hydraulic power-assisted rack-and-pinion
• Material: Steel housing with internal precision-machined gear teeth
• Mounting: Subframe-mounted with tie rod connections to the front suspension
• Function: Converts rotational input from the steering wheel into linear motion to turn the front wheels, while hydraulic assistance reduces driver effort
• Common fitment: BMW E46 316i, 318i, 320i, 323i, 325i, 328i, 330i (sedan, coupe, touring, and convertible)
• Hydraulic ports: Connects to high-pressure and return lines for fluid circulation
• Wear points: Inner and outer tie rods, seals, and bushings may need replacement over time due to leaks or play

If you want, I can also prepare a shorter, market-style listing description for selling the E46 steering rack. That way it’s ready for posting.
