Original BMW Subframe Hydrobearing Mount for BMW X3 and X4 (2018–2024)

BMW's hydrobearing 33-31-6-882-543 is a fluid-filled subframe mount that insulates the suspension crossmember from the body on the G01 X3 and G02 X4. A crossmember mount sits between the subframe and the chassis. It absorbs vibration and noise while still holding the subframe firmly in place. A hydrobearing does this with a fluid-filled chamber inside the rubber, which gives it more damping than a solid bushing. This mount is made in Germany and is sold individually. It appears at position 11 on the parts diagram.

Original BMW Parts carry a 24-month parts warranty.

BMW began producing this version in April 2019. It replaces the earlier 33-31-6-874-410, which BMW lists as exchangeable retrospectively, so it also fits X3 models built before the change. Signs of a worn crossmember insulator include clunking or knocking over bumps or under acceleration and braking, extra vibration in the cabin, and a loose or wandering feel in the steering. The same number covers four-cylinder B46 and B48 engines, the B48 plug-in hybrid, and the six-cylinder B58 used in the X4 M40i.

Does it fit the X4 M40i?
Yes. BMW applies it to the B58-powered X4 M40i.
