Driveline Repair Service in Plaistow, NH

Key Drivetrain Components and Their Maintenance Needs

• Transmission: The transmission is a complex component that shifts gears to ensure the engine operates within its optimal RPM range. Regular transmission fluid changes are essential to prevent wear and tear. We recommend a transmission fluid change every 30,000 to 60,000 miles for trucks, depending on the vehicle's usage and the manufacturer's recommendations.
• Differentials: Differentials allow the wheels to rotate at different speeds, especially during turns. They require periodic oil changes to ensure smooth operation. Heavy-duty trucks and fleet vehicles should have their differential oil checked and replaced every 40,000 to 60,000 miles.
• Driveshafts and U-Joints: Driveshafts transfer power from the transmission to the axles. U-joints, which connect sections of the driveshaft, can wear out and need regular inspections. We advise checking for any play or unusual noises and having them inspected at least once a year or every 20,000 miles.
• Axles and CV Joints: Axles bear the vehicle's and its cargo's weight. In some trucks, CV joints allow the axles to flex when the vehicle goes over bumps or turns. Regular inspections for cracks, wear, and lubrication are essential. A visual inspection during routine maintenance checks, like oil changes, will also suffice.

Common Drivetrain Issues and Their Solutions

• Transmission Slipping: If your truck's transmission slips between gears or has trouble staying in gear, it could indicate worn gears or low transmission fluid. Our technicians can diagnose the issue, recommending either a fluid change or more in-depth repairs.
• Noisy Differentials: When accelerating or decelerating, a whining or rumbling sound from the differential area can signal worn bearings or low differential oil. Regular differential oil changes can prevent these issues.
• Vibrations and Noises from Driveshaft: If you notice vibrations while driving or clunking noises when accelerating or decelerating, it might be due to worn U-joints or an imbalanced driveshaft. Immediate attention is required to prevent further damage.
