I'm not sure what the name of part 26 is, connects to the control arm. Its pretty much the only original suspension component left on my car and I would like to replace it. The rubber is very warn on I feel like there is some rear sway. Do I need to drop the rear sub-frame in order to replace it? I don't think the rear sub-frame has ever been dropped and I worry about the bolts being rusted and snapping.
