Frequently Asked Questions

How do I know if my Mercedes-Benz ML-Class or GL-Class differential mount bushing is worn?

Worn differential mount bushings typically produce noticeable vibration during acceleration or when shifting into Drive or Reverse. You may also hear clunking sounds from the rear axle, feel excessive play in the differential housing when the vehicle is lifted, or observe cracked and deteriorated rubber during a visual inspection. If you notice any of these symptoms, have the bushing inspected promptly to prevent further damage to the differential assembly.

Can I replace just one differential mount bushing, or should I replace both?

While this part is sold individually, it is common practice to replace both differential mount bushings at the same time to ensure balanced suspension geometry and consistent performance. Replacing only one side may lead to uneven wear on the remaining bushing and continued vibration issues. Most technicians recommend a complete pair replacement for the best long-term results.

What is the difference between Lemforder and other aftermarket differential mount bushings?

Lemforder is the original equipment supplier to Mercedes-Benz for suspension bushings and uses the same materials, design, and manufacturing standards as factory parts. This ensures precise fitment and performance characteristics that match the vehicle's original engineering specifications. Aftermarket alternatives may use lower-grade rubber compounds that wear more quickly, whereas Lemforder bushings deliver OEM durability and longevity.

How difficult is it to replace a differential mount bushing on my Mercedes-Benz?

Differential mount bushing replacement requires lifting the vehicle safely, supporting the rear axle assembly, and removing fasteners to detach the old bushing. The job typically demands a floor jack, jack stands, a socket set, and basic hand tools. Most owners with moderate mechanical skill can complete this repair in one to two hours, though professional installation is recommended if you are unfamiliar with rear suspension work. Always consult your vehicle's service manual for exact torque specifications and safety procedures.

Will replacing the differential mount bushing require a wheel alignment?

Differential mount bushings do not directly affect wheel alignment angles. However, if the bushing was severely worn and allowed excessive differential movement, it is wise to have the rear suspension geometry inspected after replacement to confirm proper axle positioning. Your technician can advise whether an alignment check is necessary based on the condition of the worn bushing and any other suspension components observed during service.

Does this Lemforder bushing fit both gasoline and diesel Mercedes-Benz models?

Yes, this Lemforder 3591801 is engineered to fit all engine configurations across the ML-Class and GL-Class lineup, including gasoline, diesel, and plug-in hybrid powertrains. The differential mount bushing function is the same regardless of engine type; it isolates the rear axle from the frame and reduces vibration transmission. The part number and specifications remain consistent across all compatible models and model years.

Order Lemforder 3591801 today to restore smooth, quiet differential operation on your Mercedes-Benz ML or GL-Class SUV. In-stock orders ship same or next business day from our U.S. warehouse, and our fitment team is one call away if you need help confirming the right part for your vehicle.
