In my 2008 e350 the seat was moving with the weight of the passenger and disassembly shows that there is a bushing on the pivot point that sort of dissolved. Couple of pics attached. I want to source the nylon bushing, with some help here. Otherwise I can buy the whole seat adjustment sensor for about $250 from the dealer. I need two, one fore and another aft. I've looked around online for the bushing, but nothing pops up. Not sure if this is something that could be 3d printed - it really needs to be pretty solid to survive. Pic on the left is the bolt with the half of the bushing.
