Electric Power Steering Rack Drive Belt — BMW 3 Series G20/G21 / 4 Series G22/G23
Fix Steering Noise, Play, or Poor Assist on Your BMW G20/G21/G22/G23 — Replace the EPS Rack Belt.
The electric power steering rack on BMW's G20 and G22 platform uses a drive belt to transfer motor torque to the steering rack. When this belt wears or stretches, you get steering noise (squealing or clicking under input), reduced assist, or rough steering feel — especially at low speeds and parking.
This is a direct OEM-spec replacement belt — 320mm length, 24mm width, 160 helical teeth.
Why Replace the EPS Belt
- Eliminates Steering Noise: A worn belt causes squealing or clicking sounds under steering input — replacing it restores silent operation.
- Restores Full Assist: Belt slip reduces EPS motor efficiency — a new belt restores full, responsive power assist.
- Much Cheaper Than a New Rack: EPS rack replacements cost $800–$2,500+. The belt is the first thing to service when you experience these symptoms.
- OEM Spec: 320mm × 24mm, 160 helical teeth — exact match for G20/G21/G22/G23 steering rack.
