2. 6AT Rear Differential Axle Carrier 3.27 Ratio Replacement for Cadillac ATS AWD 2013-2019 23156305 84110753
When I first came across the 6AT Rear Differential Axle Carrier with a 3.27 ratio, specifically designed as a replacement for the Cadillac ATS AWD models from 2013 to 2019, I was immediately drawn to its precise fitment and adherence to original factory specifications. Knowing that this part matches OE reference numbers like 23156305 and 84110753 reassured me that it is engineered to meet the exact standards Cadillac intended. For owners of the ATS AWD who want to maintain peak performance and reliability, this axle carrier presents itself as a trustworthy solution.
One of the standout features for me is the compatibility with specific gear oil types—85W-140 or 90—which signals attention to detail and ensures that the differential will operate smoothly under the correct lubrication conditions. This is critical because the rear differential axle carrier houses crucial components like the pinion gear, ring gear, and spider gears. Since these parts endure significant stress during driving, having the right oil type helps in minimizing wear and prolonging the life of the differential.
The design aspect also caught my attention. The product description highlights that this axle carrier can either be removable or cast into the axle housing. For someone like me, who appreciates understanding how parts function, this means that maintenance or gear set access can vary depending on the specific carrier type. For removable carriers, sliding out the drive axles and removing the carrier itself allows easy access, while non-removable carriers require removing the rear cover. This flexibility indicates the product is thoughtfully engineered for real-world servicing scenarios, which is a big plus for both DIY enthusiasts and professional mechanics.
Durability is clearly a priority here. The axle carrier is commonly made from heavy cast iron, which I know provides the toughness required to withstand the torque and forces in an all-wheel-drive setup. While some performance-focused carriers use aluminum to reduce unsprung weight, the choice of cast iron for this replacement part suggests a focus on strength and longevity—ideal for daily driving and long-term reliability. This makes me confident that the product isn’t just a quick fix but a solid investment for maintaining vehicle integrity.
One important note that resonates with me is the emphasis on prompt replacement of a broken differential. The product description honestly warns that a failing differential can cause damage to other critical vehicle components, including the engine, and even lead to dangerous situations on the road. This cautionary advice underscores how vital it is to address differential issues without delay. For any Cadillac ATS AWD owner experiencing symptoms like unusual noises or handling problems, this rear differential axle carrier replacement is a timely and necessary upgrade to ensure safety and performance.
Given the complexity and weight of the product, the advice to consult professional engineers for installation is wise. I appreciate the transparency about the difficulty involved, as improper installation could lead to further issues or safety hazards. This honest guidance helps me feel more assured that by investing in this part and using expert help, I’m making a smart, informed decision that will keep my vehicle running smoothly.

Buying Guide: 2013 Cadillac ATS Rear Differential
Understanding the Rear Differential
When I first looked into replacing the rear differential on my 2013 Cadillac ATS, I realized how crucial this component is. The rear differential helps transfer power from the engine to the rear wheels, allowing them to rotate at different speeds, especially when turning. This ensures smooth handling and traction, so it’s vital to choose the right one.
Types of Rear Differentials
I found that there are a few types of rear differentials commonly available: open, limited-slip, and electronic. The 2013 Cadillac ATS typically comes with a limited-slip differential, which improves traction by distributing power to the wheel with more grip. Understanding this helped me decide what kind of replacement would best suit my driving needs.
OEM vs. Aftermarket Options
One of the first choices I faced was whether to go with an OEM (Original Equipment Manufacturer) rear differential or an aftermarket one. OEM parts offer guaranteed fit and performance since they’re made specifically for the ATS. Aftermarket options sometimes provide enhancements or cost savings, but I had to carefully research compatibility and quality before making a decision.
Condition: New, Used, or Rebuilt
Budget played a big role in my decision-making. New rear differentials come at a premium but offer the longest lifespan. Rebuilt units can be a good middle ground, as they are refurbished to meet standards but cost less. Used differentials are the cheapest but carry risks regarding wear and reliability. I weighed these factors based on my budget and how long I planned to keep the car.
Compatibility and Fitment
It was essential for me to verify that any rear differential I considered was compatible with my 2013 Cadillac ATS model, including the specific engine and drivetrain configuration. I double-checked part numbers and consulted vehicle specifications to avoid any installation issues.
Installation Considerations
Installing a rear differential is not a simple DIY task for most people. I knew I would need professional help or a well-equipped workshop. Additionally, after installation, proper alignment and fluid replacement are necessary to ensure optimal performance and longevity.
Signs You Need a Replacement
Before buying, I made sure the rear differential truly needed replacing. Common signs include unusual noises like whining or clunking, fluid leaks, or poor handling during turns. Confirming these symptoms helped me avoid unnecessary expenses.
Price and Warranty Factors
I compared prices from different sources but also paid attention to warranty terms. A good warranty can provide peace of mind, especially with such a critical component. Sometimes spending a bit more upfront saved me from costly repairs down the road.
Final Thoughts
Buying a rear differential for my 2013 Cadillac ATS required balancing cost, quality, and compatibility. Taking the time to understand the component and evaluating all options helped me make an informed choice. I recommend anyone in a similar situation to do thorough research and consult trusted mechanics before making a purchase.
