Jeep XJ Dana 44 For Sale: The Ultimate Guide to Finding Your Holy Grail Axle

What Exactly is a Jeep XJ Dana 44?

The Dana 44 is a robust automotive axle manufactured by Dana Holding Corporation, widely regarded for its strength and versatility. In the context of the Jeep Cherokee XJ, the Dana 44 rear axle was a factory option, primarily found in 1987 to 1989 (and some early 1990) models that came equipped with the factory "tow package" (code XJ7 or 535). Unlike the more common Dana 35 or Chrysler 8.25, the XJ Dana 44 boasts a significantly stronger ring and pinion gear, larger 30-spline axle shafts, and a more robust housing.

Its appeal lies in its direct bolt-in nature for any XJ Cherokee from 1984-2001. The leaf spring perches and shock mounts are correctly positioned for a seamless swap, eliminating the need for extensive fabrication often required when adapting axles from other Jeep models or platforms. This makes the Jeep XJ Dana 44 for sale a highly desirable commodity in the aftermarket, often referred to as the "holy grail" upgrade for serious XJ builds.

Why Upgrade to a Dana 44 for Your XJ?

The decision to seek out a Jeep XJ Dana 44 for sale is driven by several compelling advantages:

1. Superior Strength and Durability: The primary reason for the upgrade. The Dana 44 can reliably handle larger tires (typically 33-35 inches, and even 37s with further reinforcement), more aggressive off-roading, and the increased stress from engine modifications. Its larger ring and pinion and thicker axle shafts are far less prone to failure than the stock Dana 35, especially when subjected to heavy articulation, low gearing, or locked differentials.
2. Enhanced Performance: With a stronger axle, you gain confidence to tackle more challenging trails without fear of breaking components. This allows for more aggressive driving, better traction, and ultimately, a more enjoyable off-road experience.
3. Vast Aftermarket Support: The Dana 44 is one of the most widely supported axles in the aftermarket. This means an abundance of options for lockers (selectable, automatic, limited slip), various gear ratios, heavy-duty axle shafts, disc brake conversion kits, and truss systems to further strengthen the housing. This allows for tailored customization to meet specific performance needs.
4. Direct Bolt-In Convenience: For XJ owners, the genuine XJ Dana 44 is a rare gem because it requires minimal modification to install. This saves significant time, effort, and money compared to fabricating mounts or adapting other axles.
5. Increased Resale Value: An XJ equipped with a properly installed and functional Dana 44 axle often commands a higher resale value within the enthusiast community, reflecting the significant investment and performance enhancement.

Identifying a Genuine XJ Dana 44: Don’t Get Fooled!

When looking for a Jeep XJ Dana 44 for sale, it’s crucial to be able to identify an authentic XJ-specific unit. Many sellers may mistakenly (or intentionally) list Dana 44s from other Jeep models (like TJ Wranglers, YJ Wranglers, or ZJ Grand Cherokees) as suitable for an XJ. While these are Dana 44s, their spring perches, shock mounts, and overall width often differ, requiring significant fabrication to fit an XJ.

Here’s what to look for:

• "44" Casting: The most obvious sign is the "44" cast into the webbing of the differential housing itself.
• Differential Cover Shape: The Dana 44 has a distinctive oval-shaped differential cover with 10 bolts.
• Leaf Spring Perches: This is the critical differentiator for XJ compatibility. The leaf spring perches should be welded directly to the axle tubes at the correct XJ width (approximately 42 inches center-to-center). They should also be positioned above the axle tubes for a standard spring-under-axle setup.
• Shock Mounts: The shock mounts should be located on the rear side of the axle tubes, specific to the XJ’s shock geometry.
• Brake Type: Most factory XJ Dana 44s came with drum brakes. While disc brake conversions are popular, a factory drum setup is usually a good indicator of an original XJ unit.
• Absence of ABS: The vast majority of factory XJ Dana 44s did not come with ABS sensors or provisions.

Always ask for clear, detailed photos of the axle, focusing on the differential, spring perches, and shock mounts. If possible, measure the distance between the spring perch centers to confirm XJ fitment.

Where to Find a Jeep XJ Dana 44 For Sale

Finding a Jeep XJ Dana 44 for sale can be a challenge due to their rarity, but persistence pays off. Here are the most common sources:

• Junkyards/Salvage Yards: This is often the best place to find an original XJ Dana 44. Look for 1987-1989 XJs, especially those with factory tow hitches, as this was the primary indicator of the Dana 44 option. Be prepared to do some digging and potentially pull the axle yourself.
• Online Forums & Social Media Groups: Dedicated Jeep XJ forums (e.g., NAXJA, CherokeeForum.com, JeepForum.com) and Facebook Marketplace groups (e.g., Jeep XJ Parts For Sale, XJ Cherokee Classifieds) are excellent resources. Many enthusiasts sell parts from their builds or parted-out Jeeps.
• Local Classifieds (Craigslist, Kijiji): Search locally. Sometimes a forgotten XJ with a Dana 44 will pop up.
• Specialized Jeep Salvage Yards/Parting Out Operations: Some businesses specialize in parting out Jeeps and may have an inventory of these axles, though they often come at a premium.
• Word of Mouth: Let your local Jeep club or off-road friends know you’re looking. Someone might know a guy who knows a guy.

When searching online, use specific keywords like "Jeep XJ Dana 44 rear axle," "XJ D44," or "Cherokee Dana 44 tow package."

What to Look For When Buying a Used XJ Dana 44

Once you’ve located a potential Jeep XJ Dana 44 for sale, a thorough inspection is crucial to ensure you’re getting a worthwhile investment. A bad axle can quickly turn into an expensive headache.

• Housing Straightness: Visually inspect the axle tubes for any signs of bending or bowing. A bent housing is a major issue that can lead to premature bearing wear and alignment problems. If possible, roll the axle on a flat surface to check for wobble.
• Rust and Corrosion: Surface rust is common and generally not a concern. However, deep pitting, scaling rust, or rot, especially around the welds (spring perches, shock mounts), indicates severe corrosion that could compromise structural integrity.
• Fluid Condition and Leaks: Check for oil leaks around the pinion seal, axle seals, and differential cover. If the cover is off, inspect the differential fluid. It should ideally be clean, not milky (water contamination), or filled with excessive metallic flakes (worn gears/bearings).
• Gears and Differential: If the differential cover is off (or you can remove it), inspect the ring and pinion gears for chipped teeth, excessive wear patterns, or pitting. Spin the pinion by hand to feel for excessive play or grinding. Ask about the gear ratio; it’s often stamped on the ring gear.
• Axle Shafts: Inspect the splines on the ends of the axle shafts for twisting or wear. Look for any bends in the shafts themselves.
• Bearings and Seals: While difficult to fully assess without disassembly, check for play in the wheel bearings and pinion bearing. Excessive play indicates worn bearings.
• Brake Components: If it comes with the drum brakes, assess their condition (shoes, drums, hardware). These may need replacement, or you might plan a disc brake conversion anyway.
• Mounts and Perches: Ensure the spring perches and shock mounts are intact, not bent, cracked, or severely rusted.

Practical Advice: Always try to inspect the axle in person. If that’s not possible, request a video walk-around and specific, high-resolution photos of all the areas mentioned above. Don’t be afraid to ask detailed questions about its history, mileage (if known), and why it’s being sold.

The Buying Process: Tips for a Smooth Transaction

• Communicate Clearly: Be specific about what you’re looking for and ask direct questions.
• Negotiation: Most prices for used axles are negotiable. Do your research on current market values to make an informed offer.
• Payment: For local pickups, cash is often king. For shipped items, use secure payment methods that offer buyer protection if possible.
• Transportation: Axles are heavy and bulky. Plan how you will transport it (truck, trailer, freight shipping). If shipping, ensure it’s properly secured and protected.
• Get a Bill of Sale: Even for a used part, a simple bill of sale can be helpful, especially if you ever need to prove ownership or deal with unforeseen issues.

Installation Considerations and Costs

While the XJ Dana 44 is a "bolt-in" upgrade, it’s not simply unbolt-and-rebolt. Be prepared for additional steps and potential costs:

• U-Bolts: You’ll need new U-bolts as the Dana 44 axle tubes are larger than the stock Dana 35/Chrysler 8.25.
• Brake Lines: Depending on the condition and your setup, you may need new flexible brake lines.
• Brakes: If it comes with drum brakes, you might want to rebuild them or upgrade to a disc brake conversion (e.g., using Ford 8.8 or ZJ Grand Cherokee rear disc brakes). This adds significant cost but improves braking performance.
• Gear Ratio Matching: This is perhaps the most critical and potentially expensive consideration. Your new Dana 44 will likely have a different gear ratio than your front axle. For proper 4WD operation, both front and rear axles must have the same gear ratio. If they don’t match, you’ll need to re-gear either the new Dana 44, your front axle, or both. Re-gearing typically costs $500-$1000 per axle for parts and labor.
• Driveshaft: While the XJ Dana 44 typically uses the same U-joint size as the stock XJ driveshaft (1310 series), if you re-gear, you might consider a stronger driveshaft or a slip-yoke eliminator for the transfer case, which often goes hand-in-hand with larger tires and lower gearing.
• Labor Costs: If you’re not doing the installation yourself, factor in professional shop labor. This can range from a few hundred dollars for a basic swap to over a thousand if re-gearing and other modifications are involved.

Common Pitfalls and How to Avoid Them

• Buying the Wrong Axle: As mentioned, ensure it’s a genuine XJ Dana 44. Avoid TJ/YJ/ZJ axles unless you’re prepared for extensive fabrication.
• Ignoring Internal Condition: A cheap axle with bad gears, bearings, or a bent housing can quickly exceed the cost of a higher-priced, healthier unit once rebuild costs are factored in.
• Not Matching Gear Ratios: Operating with mismatched gear ratios in 4WD will destroy your transfer case and axles. Always confirm and match ratios.
• Overpaying: Research market prices and understand what you’re getting for the money. A "complete" axle might still need a rebuild.
