How to Change BMW Rear Differential Fluid – Easy DIY Guide & Why It's Important!

In this video, I’ll show you how to change your BMW’s rear differential fluid step-by-step—without needing a jack! The rear differential connects the engine and transmission to the rear wheels, and old fluid can cause poor performance, rear wheel shudder, lower MPG, and even differential failure. Keeping it fresh ensures a smoother, more efficient drive.
