Driveline Repair
Precision Service, Reduced Vibration, and Restored Power Transfer
Monson Truck & Trailer Repair specializes in comprehensive driveline repair for heavy-duty semi trucks, ensuring smooth torque transfer, minimal vibration, and safe operation. From driveshaft balancing to universal joint rebuilds, our certified technicians restore your driveline’s integrity—preventing costly downtime and premature component failure.
Why Driveline Integrity Matters
Why Driveline Integrity Matters
Your driveline components—driveshafts, universal joints, slip yokes, and torque tubes—are responsible for transmitting engine power to the rear axles. When any part begins to wear or become unbalanced, you’ll experience:
- Increased Vibration & Noise: Shafts out of balance or worn U-joints cause driveline shudder.
- Accelerated Wear: Damaged components accelerate wear on transmissions, differentials, and bearings.
- Reduced Fuel Efficiency: Misaligned or binding parts increase parasitic drag.
- Potential Safety Hazards: A failed U-joint or driveshaft can separate at speed.
Monson’s Driveline Repair service addresses these issues with precision diagnostics, proper alignment, and component rebuild/replacement—keeping your truck running smoothly and safely.
How Our Driveline Repair Process Works
How Our Driveline Repair Process Works
Initial Diagnostic & Road Test
- Technician conducts a road-test to confirm vibration frequency, noise patterns, and impact conditions (idle, cruise, under load).
- Perform quick visual inspection of driveshaft angles, u-joints, and mounting points.
Shop Inspection & Measurement
- Remove driveline assembly for bench inspection.
- Use digital dial indicators and runout gauges to measure shaft straightness and phasing.
- Check universal joint caps, bearing clearances, and seal conditions.
Component Rebuild or Replacement
- U-Joint Service: Install OEM-grade bearing caps, seals, and gun-pressure grease fittings; torque to spec.
- Slip Yoke Replacement: Replace worn yokes, measure correct driveline length, and set proper slip-yoke engagement.
- Center Bearing & Torque Tube: Replace worn rubber isolators and reindex torque tube for optimal phasing.
Dynamic Balancing & Assembly
- Rebalance shafts on computerized spin-balancer to correct weight distribution and eliminate vibration at target RPM.
- Reassemble multi-piece shafts with proper phasing (ensuring yoke ears align).
Reinstallation & Final Road Test
- Reinstall driveline assembly, torque all fasteners to manufacturer specifications.
- Conduct final road-test under various loads/speeds to verify vibration elimination and smooth power delivery.
- Provide customer with diagnostic report, before/after vibration readings, and recommended maintenance intervals.
Key Benefits of Professional Driveline Repair
Key Benefits of Professional Driveline Repair
Eliminate Harmful Vibration
Balanced driveline prevents premature wear on transmission seals, differential bearings, and tires.
Extend Component Life
Rebuilt U-joints, new slip yokes, and properly aligned torque tubes reduce stress on adjacent systems.
Improve Fuel Efficiency
A properly phased, vibration-free driveline reduces parasitic drag, saving up to 1–2 MPG.
Enhance Safety & Comfort
Smooth power transfer reduces noise, cabin shake, and risk of catastrophic driveline failure.
Minimize Downtime
Accurate diagnostics and same-day balancing options allow you to return to service quickly.

Frequently Asked Questions
How do I know if my driveline is out of balance?
Common symptoms include vibration or “shudder” at specific RPM ranges (typically 40–65 MPH), clunking noises on acceleration/deceleration, or excessive wear on rear transmission seals.
What causes U-joint failure?
Lack of lubrication, misalignment, excessive operating angles, or material fatigue. Regular greasing and inspection every 25,000 miles can prevent premature failure.
Can you balance a multi-piece driveshaft on-site?
Yes. Our mobile balancing truck is equipped with a computerized spin-balancer capable of handling most multi-piece shafts—no need to transport to the shop.
How often should I service my driveline?
We recommend a driveline inspection and lubrication every 50,000 miles under normal highway use. Heavy stop-and-go or off-road conditions may require service every 25,000 miles.
What is “phasing” in a multi-piece driveshaft?
Phasing refers to the orientation of the yoke ears on each U-joint. Proper phasing ensures that both U-joints operate at the same angle, reducing vibration and torque spikes.
