2880-14 – Center Support Bearing – Mercedes Application – 1.181″ ID – 2.375″ Center Bearing To Base

Q: This is the fifth 2.375" Mercedes center bearing SKU (2880-14, 17, 55, 56, and an earlier entry). Is this range really this wide? A: Yes. Mercedes-Benz introduced the C-Class in multiple wheelbase configurations, produced E-Class in sedan, wagon, coupe, and convertible body styles, built the S-Class across several generations, and produced commercial vans and SUVs -- all potentially using the same nominal center bearing height for different chassis geometries. The bracket arm angle, mounting slot width, and isolator shape are different for each, which is why so many SKUs exist at the same dimension.

Q: When is it acceptable to reuse the old inner ball bearing with a new housing for a 2880-14 center support bearing replacement? A: Reuse of the inner bearing is acceptable only if: (1) the bearing spins smoothly with no roughness or drag, (2) there is no perceptible radial play when checked by hand, (3) the seals are intact and not weeping grease, and (4) the bearing shows less than 80,000 km since last replacement. If any of these conditions are not met, install a new inner bearing with the housing.

Q: What is the correct reassembly torque for a Mercedes center bearing bracket? A: Mercedes specifies 25 Nm (18 ft-lb) for M8 fasteners and 45--50 Nm (33--37 ft-lb) for M10 fasteners on propshaft center bearing brackets, though always verify against the FSM for your specific chassis code.
