An Engaging Introduction: The Legend of the Dana 44 in the XJ

2000 Jeep Cherokee Dana 44 Rear Axle For Sale: The Ultimate Upgrade Guide

The Jeep Cherokee XJ, produced from 1984 to 2001, is celebrated for its unibody construction, compact size, and impressive off-road prowess right out of the factory. However, like many vehicles designed for mass production, it came with certain compromises, particularly in its drivetrain. While most XJs left the factory with a Dana 35 or Chrysler 8.25 rear axle, a select few, typically those equipped with the optional tow package, received the legendary Dana 44.

The Dana 44 is renowned for its strength, durability, and larger ring gear compared to its weaker siblings. For XJ owners looking to run larger tires, install lockers, or simply demand more from their rig on challenging trails, upgrading to a Dana 44 is almost a rite of passage. Finding a 2000 Jeep Cherokee Dana 44 Rear Axle For Sale represents a golden opportunity. It’s a direct bolt-in solution for most XJs, offering a substantial boost in reliability and capability without extensive fabrication. This article will serve as your ultimate resource in understanding, acquiring, and utilizing this highly desirable component.

Understanding the Dana 44: A Legacy of Strength

The Dana 44 axle has a storied history, serving as a workhorse in countless trucks, SUVs, and dedicated off-road vehicles for decades. Its reputation for strength is well-earned, stemming from its design:

• Larger Ring Gear: The Dana 44 typically features an 8.5-inch ring gear, significantly larger than the Dana 35’s 7.5-inch or the early Chrysler 8.25’s 8.25-inch gear. A larger gear spreads the load over more tooth surface, increasing strength.
• Stronger Axle Shafts: While factory Dana 44 shafts are stronger than Dana 35 shafts, the Dana 44 also benefits from a vast aftermarket, offering heavy-duty chromoly shafts for extreme applications.
• Robust Housing: The axle housing itself is generally thicker and more resistant to bending and breaking under stress compared to the smaller axles.



• More Aftermarket Support: Due to its widespread use, the Dana 44 boasts an unparalleled array of aftermarket parts, including lockers, limited-slip differentials, various gear ratios, and heavy-duty covers.

For the XJ, the factory Dana 44 rear axle was a rare find, usually paired with the 4.0L engine and an automatic transmission, often as part of the "Up-Country" or "Trailer Tow" packages. Its scarcity makes it highly sought after, as it provides a relatively easy path to a significantly stronger rear end without the complexities of adapting axles from other vehicles.

Why a 2000 Jeep Cherokee Dana 44 is a Hot Commodity

The specific year 2000 for a Dana 44 XJ axle carries particular appeal, though its features are largely consistent with other XJ Dana 44s from the late 90s. Here’s why it remains a coveted item:

• Rarity and OEM Fit: As mentioned, it was an optional upgrade, meaning far fewer XJs were produced with this axle compared to the Dana 35 or Chrysler 8.25. This scarcity drives demand. Its OEM nature means it’s a direct bolt-in for most XJs (1984-2001), requiring minimal, if any, modification for installation.
• Enhanced Durability for Off-Roading: For those planning to install larger tires (33 inches or more), engage in aggressive off-roading, or add a locker, the Dana 44 is a necessity. It can withstand the increased stress that would easily break a Dana 35.
• Superior Platform for Upgrades: The Dana 44’s robust design makes it an ideal foundation for further enhancements. Re-gearing for different tire sizes, adding a selectable locker (like an ARB or Eaton E-Locker), or upgrading to chromoly axle shafts are all straightforward and highly effective on a Dana 44.
• Disc Brakes: Late model XJ Dana 44s (typically 1997-2001) came from the factory with disc brakes, which are a significant upgrade over the drum brakes found on earlier XJs and most Dana 35/Chrysler 8.25 axles. This provides better stopping power, especially when running larger tires.



• Increased Resale Value: Not only does the axle itself hold value, but upgrading your XJ with a Dana 44 can also increase the overall value and appeal of your vehicle to other enthusiasts.

Key Considerations When Buying a 2000 Jeep Cherokee Dana 44 Rear Axle

Finding a 2000 Jeep Cherokee Dana 44 Rear Axle For Sale is just the first step. A thorough inspection and understanding of what you’re buying are crucial to avoid costly surprises.

1. Condition Assessment:

   • Housing Integrity: Check for bends, cracks, or severe rust, especially around the spring perches, shock mounts, and differential housing. Minor surface rust is common, but deep pitting or structural damage is a red flag.
   • Fluid Leaks: Look for oil residue around the pinion seal, axle tube seals, and differential cover. While seals can be replaced, significant leaks indicate neglect or potential damage.
   • Pinion Play: Grab the pinion yoke and try to move it up/down and side-to-side. Excessive play indicates worn pinion bearings, which require a costly rebuild.
   • Axle Shafts: If visible, check the splines for wear or damage. Look for any signs of bending (though this is hard to spot without specialized tools).
   • Brake Components: If it comes with disc brakes, inspect the rotors for deep grooves or warping, and calipers for seized pistons or leaks. Assume pads will need replacement.
   • Gear Ratio: Crucial! Determine the gear ratio before buying. This is typically stamped on the ring gear or a tag on the differential cover. You need to match your front axle’s gear ratio if you have 4WD, or plan to re-gear both axles. Common ratios were 3.55, 3.73, and 4.10.
   • Locker/LSD (if present): If the seller claims it has an aftermarket locker or limited-slip differential, verify it. Ask for documentation or inspect the differential internals if possible.

2. Source of the Axle:

   • Salvage Yard: Often cheaper, but "as-is" condition. You might get lucky, but inspection is paramount.
   • Private Seller: Can be a great source, potentially from a well-maintained build. Ask questions about its history and why it’s being sold.
   • Specialty Off-Road Shops: May offer refurbished or guaranteed axles, but at a higher price.

3. Completeness: Does the sale include everything?

   • Axle shafts (both sides)
   • Brake components (calipers, rotors, pads, backing plates, parking brake assemblies)
   • Differential cover
   • Pinion yoke (ensure it matches your driveshaft U-joint size, typically 1310 or 1330 series)
   • Spring perches and shock mounts (welded in place)

4. Price vs. Value: The price will vary significantly based on condition, completeness, gear ratio, and whether it includes a locker. A completely rebuilt axle with new gears and a locker will command a premium.

5. Shipping/Transportation: These axles are heavy! Factor in the cost and logistics of transporting it, especially if buying from a distant seller.

Installation and Integration Tips

Once you’ve secured your 2000 Jeep Cherokee Dana 44 Rear Axle For Sale, proper installation is key to realizing its benefits.

• Direct Bolt-In (Mostly): The beauty of the XJ Dana 44 is that it’s designed to be a direct bolt-in. The spring perches, shock mounts, and control arm mounts should align perfectly with your XJ’s unibody.
• Matching Gear Ratios: This cannot be stressed enough for 4WD vehicles. Your new rear axle’s gear ratio must match your front axle’s ratio exactly. Failure to do so will lead to severe drivetrain binding and damage when operating in 4WD.
• Brake System Integration:
  • If upgrading from drums to discs, you’ll need to run new hard lines and potentially a different proportioning valve to balance front-to-rear braking bias. Many XJ owners simply swap in an existing XJ disc brake proportioning valve from a junked vehicle.
  • Bleed the brakes thoroughly after installation.
• Fluid Type and Fill: Use the correct gear oil (e.g., 75W-90 or 80W-90 synthetic) and ensure the differential is filled to the proper level. If it’s a limited-slip differential, you’ll need friction modifier.
• Professional vs. DIY: While installation can be done in a driveway with proper tools and knowledge, re-gearing or installing a locker should be left to an experienced differential shop.
• Recommended Upgrades During Installation: This is the perfect time to replace worn components:
  • New pinion and axle seals
  • New differential cover gasket or RTV
  • New U-bolts for the leaf springs
  • New brake pads and rotors (if needed)
  • Consider an aftermarket heavy-duty differential cover for added protection.

Beyond the Purchase: Maximizing Your Dana 44

Having a Dana 44 is just the beginning. Its true potential is unlocked through further customization:

• Gearing Options: Re-gearing the axle to match larger tire sizes (e.g., 4.56 or 4.88 for 33-35 inch tires) will restore lost power and improve drivability both on and off-road.
• Locker/LSD Installation: Add a selectable locker (like ARB or Eaton E-Locker) or an automatic locker (like a Detroit Locker) for maximum traction on the trails. A limited-slip differential offers a good compromise for daily driving and light off-roading.
• Chromoly Axle Shafts: For extreme rock crawling or heavy abuse, upgrading to chromoly shafts significantly increases strength over the stock units.
• Heavy-Duty Differential Covers: Protect your investment with a thick, cast iron or aluminum differential cover that can withstand impacts from rocks and trail obstacles.

Potential Challenges and Solutions

• Finding One in Good Condition: Persistence is key. Check online forums, dedicated XJ groups, local salvage yards, and specialized Jeep parts suppliers.
• Matching Gear Ratios: If the axle’s ratio doesn’t match your front, you’ll need to re-gear both axles, adding significant cost. Factor this into your budget.
• Dealing with Rust: Surface rust is manageable; deep, structural rust is not. Sandblast and paint the housing if needed.
• Unexpected Damage: Even after inspection, issues can arise. Set aside a contingency budget for potential seal replacements, bearing rebuilds, or minor repairs.
• Cost of Parts/Labor: Rebuilding or upgrading components can be expensive. Get quotes from reputable shops if you’re not doing the work yourself.

Practical Advice and Actionable Insights

1. Be Patient: Don’t jump on the first Dana 44 you find. Wait for one in decent condition with the right gear ratio or at a price that justifies a re-gear.
2. Inspect Thoroughly: Bring a flashlight, a magnet (to check for non-magnetic repairs), and ideally, a knowledgeable friend.
3. Know Your Current Ratio: Before you even start looking, identify your current front and rear axle gear ratios.
4. Factor in Refurbishment Costs: Unless it’s explicitly stated as rebuilt, assume you’ll need to replace seals, bearings, and possibly brake components.
5. Don’t Be Afraid to Walk Away: A bad deal on an axle can quickly become a money pit.
