### 1. šŸ”µ The Raceway Groove Problem
The old outer race has a **curved groove** machined into its inner surface ā€” this is where the balls ran. A new bearing's outer surface is **flat/cylindrical**. This means:
- Contact will only be on the **edges** of the groove
- Could cause the new bearing to **rock slightly**
- Depends on how deep/wide that groove is
