Who Should Buy This?
Buy this if: You have a 2022 E-Class with a failed rear differential and need a direct, plug-and-play replacement without the premium price of a new unit. You understand the value of a genuine OEM part and are comfortable with a used component that has been pulled from a salvage vehicle and inspected. You need the part quickly and appreciate our policy of keeping deep stock based on sales data.
Skip this if: You require a brand-new part with a full factory warranty, or if your repair budget only allows for a unit that includes all new fluids and seals in the box. If you are unsure of your vehicle’s exact differential specification (gear ratio), confirm that before purchasing.
Frequently Asked Questions
Is this differential tested?
Yes. Every unit we sell is sourced from salvage vehicles and undergoes a visual and mechanical inspection for major damage, leaks, and integrity of the mounting points. We classify it as tested functional based on this inspection and the vehicle’s operational status prior to dismantling.
What gear ratio is this?
The gear ratio is specific to your E-Class’s model, engine, and drive configuration. The ratio is stamped on the original housing. We strongly recommend you verify the ratio from your old unit or your vehicle’s data card before ordering, as this is critical for proper operation.
Does it come with a warranty?
Yes. This part is covered by our standard 30-day warranty against defects in material and workmanship (as a used part). This is a key reason our customer satisfaction score for this item is 4.7 out of 5—we stand behind what we sell.
Do I need to change the fluid?
Absolutely. You must drain the existing fluid and refill with new, correct-specification Mercedes-Benz differential fluid (typically SAE 75W-85) upon installation. This is non-negotiable for the longevity of the unit.

How is it shipped?
