Key Features
This isn’t just a part in a box to us. I’ve pulled this specific differential off the shelf, checked it over, and sent it out to dozens of customers. It’s a direct-fit replacement for the 2017 Buick Enclave, designed to restore proper power distribution to the rear wheels. The unit we’re offering is a complete assembly, ready for installation. In our visual inspections, which we perform on every single unit before it ships, this model consistently shows clean casting, proper gear machining, and the correct factory finish. We keep a deep stock of over 20 units on hand at all times because, frankly, backorders on this specific component are a major headache for shops and DIYers alike. Having it ready to go saves our customers weeks of downtime.

Pros and Cons
✅ Pros:
- Proven Fit: With over 134 units sold and a low return rate, our customers report this drops right in place when replacing a failed unit.
- Immediate Availability: We stock over 20 units because demand is steady. You get it now, not in 6-8 weeks.
- Cost-Effective: Priced significantly below a brand-new or remanufactured unit, offering solid value for a quality used assembly.
- Pre-Ship Inspection: Every unit gets our eyes on it. We look for clean gear teeth, intact mounting ears, and smooth seal surfaces before it ever leaves our warehouse.
- Complete Assembly: Comes as a full unit—just swap your axle shafts over and install.
❌ Cons:
- Used Component: This is a salvaged part, not new. It shows typical wear but is fully functional.
- No Long Warranty: We offer a 30-day return window for core exchange, but not a 12-month parts warranty like some remanufacturers.
- Fluid Not Included: You’ll need to supply and fill with new gear oil upon installation.
Who Should Buy This?
Buy this if: You’re a technician, experienced DIYer, or shop owner with a 2017 Buick Enclave in the bay right now with a confirmed bad rear differential. You need a correct, functional unit that you can get your hands on quickly to get the vehicle back on the road without paying a premium for a remanufactured core. You understand the value of a pre-inspected used OEM part.
Skip this if: You require a brand-new part with a multi-year warranty for peace of mind, or if you are unsure of your diagnosis and may need the extended support of a nationwide parts store chain. Also, if your vehicle has a modified or non-standard gear ratio, this stock 3.16 unit won’t be the correct fit.
Frequently Asked Questions
Is this a direct bolt-on replacement for my 2017 Enclave?
Yes. This is an OEM differential taken from a 2017 Buick Enclave. It is a direct replacement for your original unit. We verify fitment and condition before shipping.
What condition is the differential in?
It is a used, fully functional assembly from a low-mileage donor vehicle. We inspect each one for obvious physical damage, clean gear teeth, and intact mounting points. It is not remanufactured, but it is tested and inspected.
Do you offer a warranty?
We offer a 30-day return policy for a core exchange if the unit is defective upon arrival. This is not a long-term parts warranty. Our low return rate of about 4% on this item, based on 25 buyer ratings averaging 4.6/5, indicates a high level of customer satisfaction with the product’s condition and function.
