In the 1980s, Jeep introduced the Cherokee XJ, a car that was manufactured until 2001, and is considered one of the most iconic Jeep models. In addition to its rugged design and reliability, the XJ is well known for its off-road capabilities. It is worth noting that not all XJ years were created equal-some exhibited durability and performance, while others exhibited weaknesses. Whether you are interested in buying one or simply curious about its history, this detailed guide will discuss the best and worst Jeep XJ years.
Jeep XJ Models
Wrangler Unlimited JK, the current generation of Jeep’s seven-slot SUV, is one of its most versatile and popular models. The 4×4 has four doors, solid front and rear axles, and a variety of interior comforts that make it a popular choice among hardcore and recreational enthusiasts. For many builders, the Unlimited JK simply isn’t within their reach despite its great builder platform. When it comes to building a four-door SUV, there’s a more budget-friendly alternative.
There is no rival to the 1984-2001 Jeep Cherokee XJ when it comes to aftermarket support, mass availability, and general simplicity. Unlike any other SUV, the Jeep Cherokee has gained a large following of enthusiasts. A Jeep Cherokee XJ is the ideal vehicle for wheelers of all levels, whether they’re desert racers, rockcrawlers, or weekend warriors. The fact that they are still popular today is no surprise, however, since they are equipped with solid front and rear axles, multilink front suspension and leaf-sprung rear suspension, as well as beefy drivetrains.
The Cherokee’s unified chassis may not be as durable as a body-on-frame body, but welding can be done to the sheetmetal structure, and the unified chassis can be strengthened with options and kits. Despite a long production run and high production numbers, the market price of the XJ dropped dramatically over the last decade. Many Cherokee builders often consider them disposable vehicles because they are so cheap. As a result, you can take all the sturdy aftermarket parts available for a Jeep Cherokee XJ and move them over to another Cherokee XJ after the Cherokee’s body is pulverized by years of off-roading.
A monumental SUV with a solid front axle that was the last of its kind in North America, the Jeep Cherokee XJ left an indelible mark on the hobby and industry. There are some years of the Cherokee that are considered better than others, just as there are many other vehicles. We have gathered what you need to know about Jeep Cherokee XJ projects before you start looking.
What Makes the Jeep XJ Special?
It was a groundbreaking vehicle in the automotive world when Jeep Cherokee XJ was introduced. Having a unibody platform made this one of the first SUVs to offer a combination of comfort and strength. As a result of its boxy design, coupled with its powerful inline-six engines, the XJ proved to be a practical and capable vehicle.
Key features include:
- Unibody construction: Improved handling and weight reduction.
- Legendary 4.0L inline-six engine: Powerful and reliable.
- Compact size: Ideal for urban driving as well as trails.
- Aftermarket support: Extensive customization options.
Best Jeep XJ Years
It is one of the most reliable, powerful, and luxurious Jeep XJ models available on the market. Here are some of the most memorable years in history.
1. 1991–1996: Golden Era of the XJ
A number of factors contributed to the Jeep XJ’s success during the early to mid ’90s, including improved engine performance, durable components, and minimal reliability issues.
- Engine Upgrade: In 1991, Jeep began using a Chrysler-designed high-output fuel injection system to replace the Renix fuel injection system. It is legendary how long the inline-six engines lasted during this time period.
- Refined Design: Despite its utilitarian appearance, the interior has been modernized.
- Fewer Electronic Issues: As a result, these models were easier to maintain since they didn’t have the complex electronics found in later models.
- 1996: The Sweet Spot: There will be no significant design or electronic changes this year, marking the end of an era. A balanced combination of modern features and robust engineering makes the 1996 XJ a popular choice among enthusiasts.
2. 1984–1986: The Pioneers
Although not as technologically advanced as some of their successors, the early XJs are still worthy of acclaim. Unibody SUV concepts were introduced with these models, paving the way for decades of success to come.
- Innovative Design: This construction was revolutionary due to its lightweight design.
- AMC Legacy: XJ models of the early 1950s had the rugged engineering that was a hallmark of American Motors Corporation (AMC).
3. 1997–1999: The Modernized XJ
A refresh of the XJ with updated styling and enhanced safety features was introduced in the late 1990s.
- Exterior Redesign: Jeep rounded the XJ’s headlights and revised the grille to make the SUV look more modern.
- Improved Interior: Added sound insulation and better seating comfort.
- Strong Drivetrain: A 4.0L engine mated to a durable AW4 automatic transmission remains one of the highlights of the car.
Worst Jeep XJ Years
There are some issues with certain model years of the XJ that detract from the ownership experience. This is despite the fact that the XJ has a strong reputation. In this article, we’ll look at the worst Jeep XJ years and why they’re deemed problematic.
1. 1987–1990: Early Fuel Injection Issues
Renix fuel injection systems were introduced during these years, which while innovative were less reliable than Chrysler systems later on.
- Fuel Injection Problems: The Renix system was less compatible with modern diagnostic tools and often resulted in inconsistent performance.
- Electrical Gremlins: Gauges, lights, and other components often malfunctioned due to wiring issues.
2. 2000–2001: The Decline of the XJ
XJ production was at its lowest point in the last few years of production. Several problems were introduced with these models, along with some updates.
- Low-Quality Cylinder Heads: Models from 2000 and 2001 were equipped with low-quality 0331 cylinder heads, which are prone to cracking and require expensive repairs.
- Overheating Issues: Warm climates exacerbate engine problems caused by poor cooling system design.
- Increased Electronics: The electronics in these cars were more prone to failure than in earlier XJs, which were beloved for their simplicity.
3. 1984–1985: First-Year Gremlins
XJs of the early generation suffered from some teething problems, as do many first-generation cars.
- Underpowered Engines: Both the 2.5L four-cylinder and the early V6 were underpowered.
- Build Quality: Initially, the body panels had rust issues, particularly as the model was a first of its kind.
Things to Know Before Buying Jeep Cherokee XJ
Engine
It was 1987 when the much-loved 4.0L inline-six engine made its debut. In the first run of the 4.0L, the closed-loop cooling system was known to be problematic but can be easily upgraded to the later-model open-loop system. In 1991, Jeep added 190 horsepower to the 4.0L High-Output version, which had a multiport fuel-injection system.
Despite a few tuning upgrades, such as the introduction of equal-length intakes in 1999, and the introduction of spark packs in 2000, the classic inline remained largely unchanged. There are two main causes of leaky rear main seals: cracked headers and leaking rear main seals. It has been reported that the 4.0L can go well past 200,000 miles despite these slight negatives.
It is highly recommended that you avoid the early Cherokees (from 1984 to 1986). There were two engine options: the 2.5L four-cylinder engine or the 2.8L V-6 engine. In our opinion, the early-year engines are less than worthy of the XJ platform, and unless you are considering a complete powertrain replacement, we suggest you pass on both.
Transmission
XJs are most often equipped with automatic transmissions. Following 1987, all automatic transmissions were made by Aisin-Warner. In general, the AW-4 is trouble-free if it is cared for and maintained correctly. The AX-15 five-speed manual is available on 1989-and-newer XJs, which will be a good choice for those who value the freedom of the gearshift. 2000 saw the introduction of the highly sought-after NV3550 five-speed manual, but it’s unlikely to find one at a low price.
In early models of four-cylinder engines, a manual transmission was paired with an AX-4 and an AX-5. If possible, you should avoid both stick boxes. Six-cylinder engines were paired with Peugeot BA-10 manual transmissions for XJ models produced from 1987 to 1989. There is no doubt that the BA-10’s gearbox is a ticking time bomb, as opposed to the AX-5, which is simply weak.
Transfer Case
Even though we’ve established that the pre-1987 Cherokees aren’t the golden years, we’ll explore the transfer-case options available on earlier models. Early model transfer-case options do not necessarily perform better than later model options, but lack the same quality aftermarket support and attention as those found in post ’87 XJs, such as the NP207, NP228, or NP229 (full-time cases).
There were two different NP231s and NP242s, but both have the same 2.72:1 low range and aftermarket goodies like 4:1 gear-reduction kits, slip-yoke eliminators, and wide-chain upgrades. For drivers who frequently drive on snowy roads, a part-time option was available for the NP242.
Axles
In most cases, the XJ’s Dana 30 high-pinion front axles were vacuum-disconnectable between 1984 and 1991. It can be problematic to use these old-style disconnect systems over time, especially as they age. Many upgrades and options are available for improving or bypassing the system, such as replacing the passenger axleshaft with one-piece or installing a cable-actuated system, such as 4×4 Posi-Lok. Dana 30 front axles with low pinions were used in the last two years of Cherokee production. As we look back, it is clear the low-pinion front axle borrowed from TJ parts line was a red flag indicating the XJ’s demise.
It is never a fun sight to see a Dana 35 rear axle on an off-road vehicle. Over the course of the Cherokee’s long history, both C-clip and non-C-clip versions of the 35 were mounted under the back. Additionally, all Cherokees came with ABS starting in 1989. The brake nanny should be removed if you are able to find one without it. If you are planning an axle swap, you may have to deal with a warning light on the dash if you are using an early ABS system.
There are a few Cherokees with a Dana 44 rear axle from 1987 to 1989, but those are rare. Generally, we look for a model XJ from the mid- to late-90s with an 8.25-inch Chrysler 29-spline rear axle. The Dana 35 doesn’t get much better than this, but it’s a solid performer with a locker and 33-inch tires.
Interior
In terms of interior upscaleness, Cherokees offer leather- and cloth-filled versions, depending on your personal preference. Despite the XJ’s generous cab and comfy interior, the ’97-to-’01 XJ’s interior (shown here) has a more refined look. While the interior of the Cherokees from 1984 to 1996 does not look bad, when compared side by side, the older style looks outdated. There is a great deal of functionality and comfort in both setups.
Rear gate
Older Cherokees often have cracks around the windows and edges of the hatch. The rear hatch of the Cherokee was made of fiberglass from 1984 to 1996. Steel was replaced by aluminum in 1997 by Jeep. In the event of a cracked fiberglass gate, it wouldn’t be a deal breaker for us, but it would allow you to take a few dollars off the asking price.
What years are the Jeep XJ?
During the period 1983-2001, Jeep manufactured and marketed Jeep Cherokees (XJ) across a single generation in the United States – and worldwide through 2014. There were two- and four-door models, five-passenger options, front-engine models with rear-wheel drive, and four-wheel drive models with four-wheel drive.
Why is the XJ so good?
A remarkable engine powered the XJ Cherokee. The result was legendary when Chrysler added fuel injection. A 4.0-liter engine of that size produced 190 horsepower and 225 lb-ft of torque at the time. Although the Jaguar XJ wasn’t a speed demon, it had surprising acceleration thanks to its torque.
