Axle, CV joint, and driveshaft repairs are important components of a vehicle’s drivetrain system. Here’s an overview of each component and common repairs:

1. Axle Repair:
   • Function: Axles transfer power from the transmission to the wheels
   • Common issues: • Bent or broken axles • Worn axle bearings • Leaking axle seals
   • Repair options: • Axle replacement (often preferable to repair) • Bearing replacement • Seal replacement
2. CV (Constant Velocity) Joint Repair:
   • Function: Allows drive shafts to transmit power through variable angles
   • Common issues: • Torn CV boot leading to grease loss and contamination • Wear from lack of lubrication • Clicking noise when turning
   • Repair options: • CV boot replacement (if caught early) • CV joint replacement • Entire CV axle replacement (often more cost-effective)
3. Driveshaft Repair:
   • Function: Transfers power from the transmission to the differential
   • Common issues: • Worn universal joints • Driveshaft imbalance • Bent driveshaft
   • Repair options: • U-joint replacement • Driveshaft balancing • Driveshaft replacement

Signs of problems:

• Vibrations while driving
• Clunking or knocking sounds
• Grease on the inside edge of tires
• Difficulty turning
• Shuddering on acceleration

Maintenance tips:

• Regular inspections of boots and seals
• Proper lubrication of components
• Addressing issues promptly to prevent more extensive damage

These repairs often require specialized tools and expertise. While some minor issues like CV boot replacement might be manageable for experienced DIYers, most axle, CV joint, and driveshaft repairs are best left to professional mechanics due to their complexity and the precision required.
