5. **Long-Term Reliability** A high-quality replacement ensures durability, reducing the likelihood of frequent repairs.

6. **Potential Cost Savings** Buying a complete set (rack, pinion, tie rods) may be more economical than replacing individual worn parts separately.

1. **Potential Quality Issues** Some aftermarket parts may have inconsistent quality, leading to premature failure or leaks.

2. **Installation Complexity** Replacing a rack and pinion requires mechanical skill, proper tools, and sometimes specialized equipment (e.g., a steering angle sensor reset tool).
