The 1979 White Truck Road Boss, a heavy-duty vehicle designed for long-haul transportation, remains a symbol of durability and strength. While modern trucks have evolved with advanced technology, the Road Boss holds a special place in trucking history for its robust performance and reliability. However, like many vintage machines, restoring a 1979 White Road Boss can present some unique challenges. In this article, we explore the process of restoring this iconic truck, troubleshooting common issues, and providing insights into maintaining such a classic piece of machinery.
The Legacy of the 1979 White Truck Road Boss
White Motor Corporation, established in 1900, was known for producing a variety of heavy-duty vehicles, including trucks and buses. By the 1970s, the company had established itself as a leader in the heavy truck industry. The Road Boss series, introduced in the 1970s, was designed to cater to the increasing demand for powerful and reliable trucks for both short and long-haul transport.
The 1979 Road Boss, powered by either a Detroit Diesel or Cummins engine, was known for its exceptional towing capacity, durable build, and the ability to handle a variety of terrain conditions. With its heavy-duty transmission and sturdy suspension system, the Road Boss was a favorite among freight companies, haulers, and logging operators.
By the late 1980s, White Motor Corporation was acquired by Volvo, and production of the Road Boss line came to an end. Despite its discontinuation, the Road Boss continues to be a nostalgic model for truck enthusiasts and collectors.
Common Issues Faced by the 1979 White Truck Road Boss
When restoring or maintaining a 1979 White Road Boss, there are several common issues to be aware of. Addressing these issues early on can help ensure that the vehicle runs smoothly and that the restoration process is successful.
1. Electrical Problems
One of the most frequently encountered problems in vintage trucks, including the 1979 Road Boss, is electrical issues. These can range from simple issues like faulty wiring to more complex problems with the alternator or battery system. The truck's electrical system was relatively basic by modern standards, but over time, corrosion and wear can lead to poor connectivity and failure to start.
Common Electrical Issues:

• Wiring damage: Wiring insulation can deteriorate over time, leading to shorts or exposed wires.
  
• Alternator issues: The alternator can fail, resulting in charging problems.
  
• Battery corrosion: The truck’s battery terminals may corrode, causing starting difficulties.
  

Solution:

• Regularly inspect the wiring harness and replace damaged or frayed wires.
  
• Test the alternator and replace it if necessary.
  
• Clean the battery terminals and check the battery's health regularly.
  

2. Engine Performance Issues
The 1979 White Truck Road Boss was typically equipped with either a Detroit Diesel or Cummins engine. While these engines are known for their reliability, they can develop issues over time, especially if the truck has been sitting idle for long periods.
Common Engine Issues:

• Fuel system problems: The fuel injectors can become clogged or damaged, leading to poor engine performance and reduced fuel efficiency.
  
• Cooling system failure: Overheating can occur if the radiator or thermostat fails, causing engine strain.
  
• Oil leaks: Aging gaskets and seals may develop oil leaks, leading to a drop in oil pressure.
  

Solution:

• Clean or replace the fuel injectors and fuel filters to ensure smooth fuel flow.
  
• Regularly flush the cooling system and replace worn hoses and thermostats.
  
• Replace gaskets and seals as part of routine maintenance to prevent leaks.
  

3. Suspension and Brake System
The suspension and brake systems on a vintage truck like the Road Boss can experience wear and tear over time. The heavy-duty suspension, while durable, can become misaligned or lose its effectiveness, especially if the truck has been heavily used or subjected to harsh road conditions.
Common Suspension and Brake Issues:

• Suspension wear: The leaf springs and shocks can wear out, leading to reduced ride quality and handling.
  
• Brake system failure: Brake pads, drums, and lines may deteriorate, causing reduced braking efficiency or complete brake failure.
  

Solution:

• Inspect the suspension system for signs of wear and replace the leaf springs, shocks, and bushings as needed.
  
• Regularly check brake pads, drums, and lines for signs of wear. Replace worn components to maintain braking performance.
  

4. Transmission and Drivetrain Problems
The transmission and drivetrain of the 1979 White Truck Road Boss were designed for rugged use, but over the years, components such as the clutch, gearbox, and differential may require attention.
Common Transmission Issues:

• Clutch wear: The clutch can become worn, especially if the truck has been driven aggressively or not maintained properly.
  
• Gear shifting issues: Difficulty in shifting gears or slipping gears can occur if the transmission is not lubricated properly.
  
• Differential failure: The differential may wear out, causing issues with power distribution to the wheels.
  

Solution:

• Regularly check and replace the clutch as necessary.
  
• Ensure proper lubrication of the transmission and gearboxes to prevent premature wear.
  
• Inspect the differential and replace worn gears or bearings.
