If you're dealing with a humming or grinding noise from your wheel, this LUK wheel bearing kit might be the fix. It's designed to replace the original wheel bearing on a range of BMW models, primarily the E46 3 Series (Saloon, Touring, Compact, Coupe from around 1998-2005) and the E85 Z4 (2003-2009). Key specs: inner diameter is 42mm, outer diameter is 75mm, and width is 37mm. It's a complete kit, ready for installation. Always double-check compatibility with your specific car's year, model, and engine using the part number (713649300) or cross-referencing with OEM numbers like BMW 33 41 2 220 987. Equivalent parts from brands like SNR, SKF, and others are listed, so you know it's a quality replacement. LUK is a trusted name in drivetrain components. A proper press and some mechanical know-how are usually needed for installation, so consider a professional if you're not comfortable doing it yourself.
