I installed a new (hydraulic) hood lift strut as the old one had taken to puking its oily guts out and refusing to assist me in the slightest. It's extremely easy to replace and the only concern, when you decide not to pay dealer prices is, "Am I getting the correct one?" Compare the strut body of the OE one to the same location on the aftermarket strut. It's 100% evident they have merely mechanically removed the Mercedes brand stamping in the same way the Egyptians removed Ramses' name from their stone monuments. "There. Now no one will ever remember who we made this unnamed statue for!" Strangely, my unmarked aftermarket strut works EXACTLY like the original Mercedes one used to! Anyway, I'll put the Amazon link but I later found it for a few dollars less at Pelican Parts, although they might charge shipping. If so then Amazon is still the least expensive.
