There are still numerous "lube" spots on the modern MB. But not in the suspension. The spots vary by model but some of the spots are: door strikers, door hinges, hood hinges, throttle linkages, door seals, hood latch and plastic hooks (rear of 126 hood), door stays, etc.
The suspension components are sealed and lubed for life (their life). It turns out that this really works better than non sealed joints that have to be lubed. The problem with non sealed joints is that water can get in where the grease gets out. Having to lube every 3000 miles would play he** with the modern service schedule.
