Thorough Quality Inspections
Our transfer cases undergo three comprehensive quality inspections during the remanufacturing process to ensure optimal performance:
- Pre-Inspection: This step verifies that the unit is free from case cracks, excessive wear, and other OEM-related problems commonly found in cores.
- Mid-Process Inspection: During the remanufacturing process, a second inspection ensures all component parts meet OEM specifications.
- Post-Build Inspection: A final inspection is conducted after the remanufacturing process to ensure the unit meets our strict quality standards.
