This product supersedes Porsche's old part numbers:
99633104506, 99633104508, 99633104510, 99633104512, 99733104504 , 99633104512

What this product does:
• Provides a secure connection between the chassis and wheel hub
• Maintains wheel alignment for safe, predictable handling
• Absorbs suspension forces while keeping steering precise

Over time, control arms can bend, wear, or develop excessive play in the bushings and ball joints. This can cause uneven tire wear, knocking noises, wheel alignment issues, and a noticeable loss of steering precision. Replacement will restore the correct wheel alignment and suspension stability for which your Porsche was designed.
