Overview

The 1987 Jeep Wrangler is a compact, body-on-frame 2-door SUV built for off-road use and open-air driving. It was the first model year of the YJ generation, replacing the CJ with a more modern interior, improved on-road manners, and wider track while keeping the classic removable top and doors. This Wrangler is ideal for buyers who want a simple, highly modifiable 4x4 for trails, beach runs, and weekend cruising rather than a quiet daily commuter. In today’s market, it sits as an affordable classic 4WD that rewards hands-on owners and buyers who value rugged character over refinement.

Key Features

- First-year YJ Wrangler (1987): Updated chassis and suspension tuning compared with the CJ, plus a more driver-friendly cabin layout and improved ergonomics. - Engine options: 2.5L inline-4 (fuel-injected) for better economy and simplicity, or the 4.2L inline-6 (carbureted) for stronger low-end torque and classic Jeep feel. - 4x4 hardware: Part-time four-wheel drive with a 2-speed transfer case (2H/4H/4L), giving true low-range capability for slow-speed crawling and steep grades. - Open-air design: Soft top or hardtop configurations, removable doors, and a fold-down windshield on many setups—key Wrangler selling points that make it a true lifestyle vehicle. - Classic YJ stance and practicality: Squared-off headlights unique to the YJ era, a short wheelbase for tight trails, and a simple, boxy cargo area that’s easy to load and modify.

Common Issues & Reliability

Owners searching “1987 Jeep Wrangler reliability” will find it’s generally durable when maintained, but age, rust, and neglected service can turn small problems into expensive projects. Common “1987 Jeep Wrangler problems” and “1987 Jeep Wrangler common issues” include: 1) Rust in the frame and body mounts: One of the biggest deal-breakers. Rust commonly shows up around spring hangers, shackle mounts, rear frame sections, floor pans, and body mounts—especially in salt states. Severe corrosion can appear well before 150,000 miles depending on climate and prior care. 2) Carburetor and drivability issues on the 4.2L inline-6: Hard starts, rough idle, stalling, and hesitation are frequent complaints, often tied to the factory carburetor, vacuum lines, and emissions controls. Problems can be intermittent and may worsen with heat soak or at higher mileage (often 80,000–140,000+). 3) Cooling system and overheating concerns: Radiators, water pumps, thermostats, and old hoses can cause temperature creep, especially in slow off-road conditions. A neglected cooling system can lead to repeated overheating episodes, typically showing up as the vehicle ages rather than at a specific mileage. 4) Steering wander and front-end looseness: Many 1987 Wranglers develop vague steering, shimmy, or clunks due to worn tie-rod ends, track bar bushings, ball joints, and steering stabilizers. Lift kits, oversized tires, or poor alignment can amplify these symptoms, often becoming noticeable around 100,000 miles or sooner if used hard off-road.
