The Best Years For Isuzu Bighorn And Some To Avoid

The Isuzu Bighorn, known in some markets as the Trooper, is a rugged and reliable SUV that has garnered a loyal following over the years. Finding the right model year can be crucial to ensuring a positive ownership experience. This guide will delve into the best and worst years of the Bighorn, providing detailed information to help you make an informed decision.

Isuzu Bighorn Model Year Overview

Detailed Explanations

1981-1991 (First Generation): The first-generation Bighorn is characterized by its robust construction and off-road prowess. Featuring solid axles and carbureted engines, these models offer a simple and reliable driving experience. Available in both short and long wheelbase configurations, they are a popular choice for enthusiasts seeking a classic off-roader. However, potential buyers should be aware of the increased risk of rust, especially in regions with harsh weather conditions. Carburetor issues can also arise due to age and wear.

1991-1998 (Second Generation - Pre-Facelift): The second-generation Bighorn introduced independent front suspension, offering improved on-road handling and comfort. Fuel-injected engines provided better fuel efficiency compared to the previous generation. The introduction of the 3.1L Turbo Diesel engine expanded the model's appeal. However, some models experienced the infamous "death wobble," a violent shaking of the front end at certain speeds, attributed to the suspension design. Early 3.1L diesel engines were also prone to cracking heads. Rust remained a concern, requiring careful inspection before purchase.

1998-2002 (Second Generation - Facelift): The facelifted second-generation Bighorn brought refined styling, improved interior materials, and upgraded engine options, including the 3.0L Turbo Diesel. These models generally offer improved reliability compared to earlier versions. While the 3.0L diesel provided more power, it was not without its issues, including oil consumption and injector problems. Later models also had the potential for electronic issues, requiring a thorough inspection.

2002-2002 (Final Year): The final year of production, 2002, represents the culmination of Isuzu's efforts to refine the Bighorn. These models are often considered the most desirable due to their latest features and improvements. However, due to limited production numbers, parts availability can be more challenging. The same potential issues as the 1998-2002 models apply, so a comprehensive inspection is still recommended.

Best Years

While personal preferences and intended use play a significant role, the 1998-2002 facelifted models generally offer the best overall balance of features, reliability, and comfort. The refinements made during this period addressed many of the issues present in earlier models.

Specifically, the 2000-2002 models are often regarded as the pinnacle of the Bighorn's evolution. They incorporated the latest upgrades and improvements, resulting in a more enjoyable and reliable ownership experience. These later models often featured better electronic systems, improved interior quality, and refined engine performance.

However, even within these "best" years, it's crucial to thoroughly inspect any potential purchase. Look for signs of rust, check for engine issues (especially with the 3.0L diesel), and ensure that all electronic systems are functioning correctly.

Years to Avoid (or Approach with Caution)

While all Bighorn models have their strengths, some years require more caution due to potential issues.

Early Second Generation (1991-1994): These models are more susceptible to the "death wobble" and early 3.1L diesel engine problems. Unless you're prepared to address these issues, it's best to proceed with caution.

Models with High Mileage and Poor Maintenance History: Regardless of the model year, a Bighorn with high mileage and a questionable maintenance history is likely to present problems. Thoroughly inspect the vehicle's service records and conduct a pre-purchase inspection by a qualified mechanic.

Models Heavily Modified for Off-Roading: While the Bighorn is a capable off-roader, heavily modified vehicles may have experienced significant stress and strain on their components. Inspect these vehicles carefully for signs of damage or wear.

Key Areas to Inspect When Buying a Used Isuzu Bighorn

Regardless of the model year, a thorough inspection is crucial before purchasing a used Isuzu Bighorn. Here are some key areas to focus on:

• Rust: Check the undercarriage, body panels, and around windows and doors for signs of rust. Pay particular attention to areas prone to water accumulation.
• Engine: Listen for unusual noises, check for leaks, and ensure that the engine runs smoothly. If possible, perform a compression test to assess the engine's health. On diesel models, pay close attention to smoke color and quantity. White or blue smoke can indicate serious issues.
• Transmission: Test the transmission for smooth shifting and proper engagement in all gears. Listen for any unusual noises or vibrations.
• Suspension: Check for worn-out shocks, struts, and bushings. Inspect the suspension components for damage or corrosion. Test for the "death wobble" by driving at various speeds on different road surfaces.
• Brakes: Inspect the brake pads, rotors, and calipers for wear and damage. Ensure that the brakes are functioning properly and that the ABS system is working correctly.
• Electrical System: Test all lights, switches, and accessories to ensure they are functioning correctly. Check the battery and charging system for proper operation.
• Interior: Inspect the interior for wear and tear. Check the seats, carpets, and dashboard for damage. Ensure that all features, such as the air conditioning and heater, are working correctly.
• Service History: Review the vehicle's service records to determine its maintenance history. A well-maintained Bighorn is more likely to be reliable.
