After year 2006 BMW switched from roller bearings to ball bearings inside differentials. Since that moment, differentials are called Type L, as for low friction. Ball bearings have lower friction coefficient compared to roller bearings, but they are way less durable, so whining noise is more than often. This kit provides everything you need to fix noisy differential problem.
L type differentials was found in following BMW models:
- 1 series: E81, E82, E87
- 3 series: E90, E91, E92, E93
- 5 series: E60, E61
- 6 series: E63, E64
- X5 series: E70
How to tell if your differential needs bearings replacement?
Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from the wheel bearing noise steer left-right like you are warming up tires for the race.
If the noise changes its intensity than it is a wheel bearing. If intensity of the noise remains the same, that means differential bearings needs to be replaced.
