What Problems Does the 1987 Peterbilt 379 Have?
The 1987 Peterbilt 379, being a vintage truck, is subject to age-related problems. Rust is a significant concern, especially in areas exposed to road salt. Frame corrosion, cab corner rust, and battery box deterioration are common. Mechanical issues, such as engine wear (especially piston rings, bearings, and valve train components), transmission problems (worn synchros, shifting difficulties), and differential failures, are frequently reported. Given the age, these are more likely due to wear and tear rather than inherent design flaws.
Electrical problems, including wiring harness degradation, faulty sensors, and gauge malfunctions, are also prevalent. Air system leaks are another common issue, affecting brakes and other air-powered components. Suspension components, such as air bags and shocks, are prone to wear and require periodic replacement.
Recalls for a 1987 model are unlikely to be relevant at this point, as manufacturers typically address safety concerns within a specific timeframe. However, checking the NHTSA (National Highway Traffic Safety Administration) website for any historical recalls related to safety-critical components is advisable. Long-term reliability depends heavily on maintenance. Neglecting routine servicing accelerates wear and tear, leading to more frequent and costly repairs. Rebuilding or replacing major components, such as the engine or transmission, might be necessary to maintain long-term operation.

How long will the 1987 Peterbilt 379 last?
Given the age of the 1987 Peterbilt 379, mileage varies considerably. Well-maintained examples can easily exceed 1 million miles, while others may have significantly less due to periods of inactivity or neglect. Years of service also vary greatly. Long-term durability hinges on consistent maintenance; regular oil changes, filter replacements, and timely repairs are crucial. Weaknesses over time include corrosion, wear and tear on mechanical components, and degradation of electrical systems. Proper storage and preventative maintenance can mitigate these issues and extend the truck's lifespan. Trucks that haven't received adequate maintenance are prone to component failures and expensive repairs.
What Technology & Safety Features are Included?
The 1987 Peterbilt 379 predates modern automotive technology. Built-in tech was limited to basic gauges (speedometer, tachometer, oil pressure, coolant temperature, etc.). Entertainment typically consisted of an AM/FM radio, possibly with a cassette player. Driver-assistance features were non-existent by today's standards; there were no electronic stability control, lane departure warning, or adaptive cruise control systems. Safety features included seatbelts and air brakes, but ABS (Antilock Braking System) may have been optional or not available depending on the specific configuration.
Optional features related to comfort and convenience were more common. These might include air conditioning, upgraded seating (air ride seats), and enhanced interior trim. CB radios were a popular aftermarket addition for communication. Safety was primarily dependent on the driver's skill and adherence to safe driving practices. Crash-test ratings are unavailable for vehicles of this era, as formal testing procedures for heavy-duty trucks were not widely established. The primary safety consideration was the sheer size and weight of the vehicle, offering a degree of protection in collisions with smaller vehicles. However, rollovers and jackknifing remained significant safety concerns. The absence of modern safety technology highlights the importance of careful driving and preventative maintenance for these older trucks. Aftermarket upgrades for safety can be added, such as better lighting, but the core safety systems are rudimentary by modern standards.

1987 Peterbilt 379 Prices and Market Value
The price of a new 1987 Peterbilt 379 varied considerably based on configuration and options, potentially ranging from $60,000 to $100,000 or more. Current used market prices are highly variable. Condition, mileage, engine, and overall originality significantly affect value. Restored or well-maintained examples can command premiums, while neglected trucks sell for much less. Depreciation has been substantial over the decades, but well-preserved or customized 379s can hold their value or even appreciate as classic trucks. Factors affecting resale value include the presence of desirable engine options (e.g., CAT 3406B), original documentation, and overall cosmetic appeal.
1987 Peterbilt 379 Cost of Ownership
The 1987 Peterbilt 379 is generally not economical to own compared to modern trucks. Insurance costs depend on usage and coverage but can be significant due to the truck's age and potential for accidents. Fuel costs are high due to lower fuel efficiency. Maintenance and repair costs are substantial, as parts can be difficult to find and labor rates for older trucks are often higher. Long-term ownership requires a dedicated owner willing to invest in upkeep and repairs. Routine servicing and preventative maintenance are essential to minimize costly breakdowns.

How Does the 1987 Peterbilt 379 Compare to Other Truck?
The 1987 Peterbilt 379 competed primarily with trucks like the Kenworth W900, Freightliner Classic, and Mack Super-Liner. In terms of performance, the 379 was comparable to its rivals, with similar engine options and power output. However, modern trucks offer significantly improved fuel efficiency and emissions control.
Regarding features, the 1987 Peterbilt 379 lacks the advanced technology found in contemporary trucks, such as electronic logging devices (ELDs), advanced safety systems, and sophisticated infotainment options. Reliability is comparable to its contemporaries, but age-related wear and tear are a major factor for all trucks of this era.
Used prices for these trucks are highly variable, depending on condition. If seeking a reliable and modern work truck, a newer Peterbilt, Kenworth, or Freightliner model would be a better alternative, despite the higher purchase price. For someone seeking a classic truck for occasional use or restoration, the 1987 Peterbilt 379 holds its own against its rivals, offering similar aesthetics and a robust design. The Kenworth W900 is a very close alternative with similar appeal and characteristics.
