What Problems Does the 1987 GMC W4S042 Have?
The 1987 GMC W4S042, being a commercial vehicle from an era where durability was paramount, generally holds up well. However, like any vehicle of this age, certain issues tend to arise. One of the most common concerns is related to corrosion. Rust can affect the frame, especially in areas exposed to salt and moisture, as well as body panels and wheel wells. Regular inspections and undercoating can mitigate this.
Powertrain components, while generally robust, can experience wear over time. This might include issues with the transmission, particularly with higher mileage or heavy use, leading to rough shifting or slippage. The 5.7L V8 gasoline engines are known for their longevity, but they can develop leaks from seals and gaskets. Diesel engines, while durable, might face issues with glow plugs, fuel injectors, or fuel pumps if not properly maintained.
Electrical systems can also be a point of concern. Older wiring harnesses can degrade, leading to intermittent problems with lights, gauges, or accessories. Battery drain issues are not uncommon.
Specific recalls for the 1987 model year are not widely documented in easily accessible consumer databases, typical for commercial vehicles where recalls were often handled through direct communication with fleet owners. However, as a general principle for vehicles of this age, it's wise to check for any outstanding manufacturer service bulletins or recalls that might still be applicable, especially if purchasing used.
Long-term reliability is heavily dependent on the maintenance history. Trucks that have been regularly serviced, with fluid changes and inspections, will far outperform those that have been neglected. The chassis and suspension components are built to be heavy-duty, but they will still experience wear and tear with use, potentially requiring replacements of bushings, ball joints, or brake components over many years.

How long will the 1987 GMC W4S042 last?
The 1987 GMC W4S042 is built for endurance, with many units logging well over 200,000 miles and continuing to serve. With consistent, diligent maintenance, including regular oil changes, transmission fluid flushes, and chassis lubrication, these trucks can realistically last 250,000 to 300,000 miles or more. Their core chassis and powertrain were designed for commercial use, meaning they are inherently more durable than typical passenger vehicles. Weaknesses that emerge over time primarily relate to wear on suspension components, brake systems, and the potential for rust on the body and frame, especially in harsh climates. However, the fundamental mechanical integrity often remains strong for many years.
What Technology & Safety Features are Included?
The 1987 GMC W4S042, as a commercial vehicle of its era, prioritizes functionality and durability over advanced technology, driver assistance, or extensive entertainment features. Built-in technology was minimal. Standard entertainment typically consisted of a basic AM/FM radio, often with a single speaker. Options might have included a cassette player. Power windows and locks were generally not standard, with manual operation being the norm.
Driver-assistance features as we know them today were virtually non-existent. The focus was on basic operation and visibility. Features like power steering and power brakes were common options that significantly aided the driver, especially when maneuvering at low speeds or under load. Air conditioning was also a popular optional upgrade for driver comfort.
Safety features were rudimentary by modern standards. Standard safety equipment would have included seat belts, likely lap belts in the standard configuration, with optional three-point belts becoming more common. The vehicle's construction provided a robust shell, offering a degree of passive safety due to its heavy-duty frame and body. However, advanced safety systems like airbags, anti-lock braking systems (ABS), or electronic stability control were not available.
Crash-test ratings from the 1980s for commercial medium-duty trucks are not readily available in the same consumer-focused databases we see today. GMC's focus at the time was on meeting industry safety standards for commercial vehicles, which emphasized structural integrity and occupant protection within the context of their intended use. The heavy-duty nature of the W4S042's construction inherently provided a level of protection due to its mass and robust frame, but specific numerical ratings are unlikely to exist or be comparable to modern standards.
