Follow these steps carefully
Park the 2006-2011 Mercedes-Benz C280 on level ground, set the parking brake, and disconnect the negative battery cable. Support the engine from above with an engine support bar or from below with a jack and a wood block under the oil pan — never leave the engine hanging on remaining mounts alone. Wear gloves and eye protection.
Identify which mount is bad (oil-soaked rubber, cracked insulator, or metal-to-metal contact) on the 2006-2011 Mercedes-Benz C280. Remove any engine covers, air boxes, or undertrays blocking access to that mount’s fasteners.
On the 2006-2011 Mercedes-Benz C280: remove the through-bolt or nuts securing the mount to the engine bracket, then the fasteners into the frame/subframe. Note any ground straps, heat shields, or alignment dowels. Lower or raise the engine slightly only as needed for clearance — do not force the mount.
Match the new mount to the old one (stud pattern, snubber orientation, and hardness marks). Seat it fully on the 2006-2011 Mercedes-Benz C280, install fasteners finger-tight first, then torque to the specified values once the engine is back at rest height.
Remove the engine support bar/jack. Confirm the 2006-2011 Mercedes-Benz C280 mount is not twisted and that hoses, belts, and wiring have clearance. Reinstall covers and reconnect the battery.
Start the 2006-2011 Mercedes-Benz C280 and check for clunks or excessive movement in gear (auto: Park-to-Drive; manual: clutch engage). Road-test for vibration under acceleration and braking. Recheck mount torque after a short heat cycle if specified.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
