Heavy-Duty Drivetrain Repair for Commercial Trucks
The drivetrain transfers engine power from the transmission through the driveline to the drive axles and wheels. When any component in that chain is worn, misaligned, or damaged, the result is vibration, noise, loss of power transfer, premature tire wear, and unplanned downtime.
Drivetrain problems often involve multiple connected components — driveshaft, U-joints, carrier bearings, differentials, axle shafts, yokes, slip joints, seals, the power divider, and inter-axle hardware. Because these parts interact, proper diagnosis is essential before parts are replaced.
CRANETEC focuses on identifying the actual source of vibration, noise, leaks, looseness, or power transfer problems — rather than replacing components blindly — for tractors, trailers, service trucks, construction fleets, utility fleets, transportation companies, and commercial vehicles.
Our Commercial Drivetrain Repair Services
Diagnostic-first repair for driveshafts, U-joints, carrier bearings, differentials, axles, and related driveline components.
Driveshaft Inspection & Repair
We inspect driveshafts for bends, balance concerns, damaged tubing, and weld integrity, then repair or replace to restore smooth power transfer.
Common Symptoms
- Driveshaft vibration
- Excessive driveline play
- Visible tubing or weld damage
Unresolved driveshaft damage can transmit vibration through the entire driveline and accelerate wear on connected components.
ScheduleU-Joint Replacement
Loose, dry, or seized U-joints create clunking and vibration. We replace worn universal joints to restore proper articulation and reduce driveline movement.
Common Symptoms
- Clunking during acceleration
- Driveline vibration
- Excessive movement at the joint
Failed U-joints can lead to driveshaft separation and a vehicle that cannot operate safely.
ScheduleCarrier Bearing Replacement
Worn center support bearings cause driveshaft instability, noise, and vibration. We replace carrier bearings to stabilize multi-piece driveshafts.
Common Symptoms
- Noise under the cab
- Driveshaft sag or instability
- Premature driveline wear
A failed carrier bearing can damage the driveshaft and surrounding supports if left unaddressed.
ScheduleDifferential Repair
We diagnose and repair differential noise, gear wear, bearing failure, and fluid leaks across drive and tandem axles.
Common Symptoms
- Whining or howling
- Gear noise under load
- Fluid leaks at the housing
Internal differential damage can progress to complete axle failure and loss of power to the wheels.
ScheduleAxle Repair
We service drive axles, axle shafts, and axle housings for bearing damage, power delivery issues, and structural concerns.
Common Symptoms
- Rear axle noise
- Power delivery issues
- Bearing-related vibration
Axle problems can prevent torque from reaching the wheels and create unsafe operating conditions.
SchedulePinion Seal Replacement
Leaking pinion seals allow differential fluid loss, which can starve internal gears of lubrication. We replace seals before internal damage develops.
Common Symptoms
- Fluid leak at the pinion
- Low differential lubricant
- Wet housing around the yoke
Low lubricant from a leaking seal can destroy ring and pinion gears.
ScheduleYoke & Slip Yoke Repair
Loose yokes and worn splines create driveline play and clunking. We repair or replace yokes and slip joints to restore secure connections.
Common Symptoms
- Driveline play
- Clunking on engagement
- Worn splines at the connection
Worn yokes accelerate U-joint and driveshaft wear and can cause vibration under load.
SchedulePower Divider Repair
We diagnose and repair power divider concerns affecting inter-axle power distribution in heavy-duty tractor applications.
Common Symptoms
- Engagement issues
- Noise from the divider
- Uneven power distribution between axles
Power divider problems can prevent proper torque sharing across tandem axles.
ScheduleInter-Axle Differential Service
We service tandem axle systems, including inter-axle differentials and differential lock concerns for heavy-duty applications.
Common Symptoms
- Differential lock not functioning
- Internal wear noise
- Power distribution problems
Inter-axle differential issues can cause tire scrubbing and uneven drive axle wear.
ScheduleDifferential Fluid Service
We inspect lubricant condition, drain contaminated fluid, and refill to correct levels as part of preventive drivetrain maintenance.
Common Symptoms
- Contaminated fluid
- Low fill level
- Metal in the lubricant
Clean, correctly filled fluid is the simplest way to extend differential service life.
ScheduleDriveline Diagnostics
We diagnose road vibration, speed-related vibration, acceleration vibration, noise under load, clunking, and unusual driveline movement.
Common Symptoms
- Vibration at specific speeds
- Noise under load
- Clunking on acceleration
Accurate diagnosis prevents unnecessary parts replacement and targets the actual source.
ScheduleFleet Drivetrain Maintenance
Scheduled drivetrain inspections covering U-joints, fluids, seals, fasteners, and driveline play to catch wear before failure.
Common Symptoms
- Developing wear found on inspection
- Loose fasteners
- Early seal seepage
Preventive drivetrain service reduces unplanned breakdowns and roadside failures.

What Causes Commercial Truck Drivetrain Problems?
Heavy commercial fleets experience higher drivetrain loads than passenger vehicles. These are the most common causes we see.
Commercial Driveshaft Repair & Driveline Vibration Diagnosis
The driveshaft carries torque from the transmission to the differential. Even small balance, angle, or wear issues translate into noticeable vibration through the cab and frame. Heavy duty driveshaft repair targets the root cause rather than masking the symptom.
Driveline vibration typically falls into patterns: speed-related vibration that worsens with road speed, acceleration vibration that appears under load, and clunking from loose U-joints or worn yokes. Commercial truck vibration repair starts with isolating whether the source is the driveshaft, a carrier bearing replacement need, U-joint replacement, yoke wear, or driveline angle.
Ignoring driveshaft vibration allows the condition to damage surrounding components — U-joints, the transmission output, carrier bearings, and differential bearings — turning a focused repair into a larger failure.
Commercial Truck Differential Repair
The differential splits torque to the drive wheels while allowing them to rotate at different speeds. Inside are ring and pinion gears, bearings, and lubricant held in by pinion and axle seals. In tandem axle systems, an inter-axle differential and power divider manage distribution between the two axles.
Differential failure symptoms include whining, howling, grinding, fluid leaks, metal contamination in the lubricant, excess heat, vibration, and power delivery problems. Internal wear and fluid contamination are the most common causes.
We diagnose the source of the noise or leak, inspect gear and bearing condition, and recommend repair — from pinion seal replacement to internal differential service — before the damage progresses.
Axle & Power Divider Repair for Heavy-Duty Trucks
Drive axles, tandem axles, axle shafts, power dividers, inter-axle differential systems, and differential lock systems all participate in delivering torque to the wheels. A problem in any of these can prevent power from reaching the wheels correctly.
We support the commercial use cases that depend on these systems — long-haul tractors, dump trucks, utility trucks, construction fleets, heavy equipment support vehicles, and regional transportation fleets.
Why Drivetrain Maintenance Matters for Commercial Fleets
Deferred drivetrain maintenance leads to unexpected breakdowns, roadside failures, towing expenses, secondary transmission damage, differential failure, driveshaft failure, missed deliveries, project delays, vehicle downtime, higher repair costs, and safety concerns.
Scheduled drivetrain inspection identifies developing problems — a leaking seal, a dry U-joint, a noisy carrier bearing — before they become a complete failure. Learn more about our fleet maintenance and preventive maintenance programs.
Our Commercial Drivetrain Diagnostic Process
A structured approach that finds the real source of vibration, noise, leaks, and power transfer problems.
Driver Complaint Review
We listen for details on vibration, noise, load conditions, speed, and when the symptom occurs.
Visual Driveline Inspection
We inspect driveshafts, yokes, U-joints, supports, leaks, and visible damage.
Driveline Play Inspection
We check for looseness, movement, or worn connection points throughout the driveline.
Differential & Axle Evaluation
We inspect fluid condition, seals, bearings, and related components at the axles.
Diagnostic Testing
We determine whether the concern originates from the driveline, transmission, axle, wheels, or another system.
Repair Recommendation
We explain our findings and the recommended service before any work begins.
Repair & Verification
We complete approved repairs and verify the condition is resolved after service.
Drivetrain Repair vs. Transmission Repair
Transmission repair concerns internal transmission operation — shifting, gears, clutch-related systems, or transmission control. Drivetrain repair concerns power transfer after the transmission — driveshafts, U-joints, carrier bearings, differentials, axles, and related components.
Because similar symptoms can come from either system, diagnosis determines the actual source. See our transmission repair page for transmission-specific concerns.
