What Problems Does the 1987 GMC R Conventional Have?
The 1987 GMC R Conventional, being a product of its era, does have some common issues that owners often report. Rust is perhaps the most prevalent concern, particularly affecting the undercarriage, frame rails, rocker panels, cab corners, and wheel wells. Vehicles from regions with heavy road salt usage are especially prone to this. The electrical system can also present challenges, with issues like faulty turn signal switches, dashboard warning lights not functioning correctly, and intermittent power to accessories being noted. The radiator and cooling system are another area where leaks can develop over time, leading to overheating if not addressed promptly. Carburetor issues, especially on V8 models, can lead to rough idling or poor fuel delivery. On manual transmissions, clutch wear is a common maintenance item. For automatic transmissions, especially the TH400 or 700R4, shifting problems or failure can occur if they haven't been properly maintained or rebuilt. The 6.2L diesel engine, while generally robust, can suffer from injector pump failures and glow plug issues. Suspension components like ball joints, tie rods, and bushings will wear out over time, leading to sloppy handling and potential alignment problems. Power steering pumps can also develop leaks. While specific model year recalls for the 1987 R Conventional are not extensively documented as major widespread issues, it is always advisable to check the National Highway Traffic Safety Administration (NHTSA) database for any specific safety recalls that may have been issued. Overall, the long-term reliability is heavily dependent on how well the vehicle has been maintained and preserved from rust. With diligent care and timely repairs, these trucks can remain dependable, but neglecting common wear items and rust prevention will lead to costly repairs and a reduced lifespan.
How long will the 1987 GMC R Conventional last?
Estimating average mileage for a 1987 GMC R Conventional is challenging due to varied usage, but well-maintained examples commonly surpass 200,000 miles. Trucks used primarily for daily driving and with regular fluid changes, rustproofing, and component replacements can easily reach 250,000 to 300,000 miles and beyond. The long-term durability is commendable, particularly for the engine and transmission in many cases. However, the primary weakness over time is susceptibility to rust, which can significantly shorten its service life if not addressed. Electrical components and suspension parts also tend to wear out, requiring eventual replacement. With proactive maintenance and rust prevention, these trucks are known for their longevity and can serve reliably for decades.
What Technology & Safety Features are Included?
The 1987 GMC R Conventional, reflecting its era, offered a rather basic suite of technology and safety features compared to modern vehicles. Built-in tech was primarily focused on functionality rather than connectivity. Entertainment options typically included an AM/FM radio, often with a cassette player as an upgrade. Higher trims might have offered more speaker configurations. There were no advanced infotainment systems, touchscreens, or smartphone integration. Driver-assistance features were virtually non-existent. Anti-lock braking systems (ABS) were available on rear-wheel-drive models, primarily for the rear wheels, and became more common towards the end of the model run as an optional feature. Cruise control was also an optional comfort feature. Safety features were standard for the time, including lap and shoulder belts, and a strong steel frame designed to absorb impact. Side-impact door beams were also incorporated. Airbags were not standard equipment in 1987, and driver-side airbags only began to appear on some vehicles in the late 80s and early 90s. Crash-test ratings for vehicles of this vintage are not readily available or comparable to modern standards like those from the NHTSA or IIHS, as testing methodologies and requirements were far less stringent. The focus was more on passive safety through structural integrity rather than active driver aids or advanced passive restraint systems. In essence, the 1987 GMC R Conventional prioritized mechanical robustness and basic utility over electronic sophistication or advanced safety technology.
