This is a time-consuming effort.<\/p>\n<p>Engineers will need to deservice the strut, remove wheels\/tires and brakes, disconnecting hydraulics and electrical lines, and remove the lower strut to allow for the replacing the seal. It will then require testing before being put back together for further testing. <\/p>\n<p>The replacement seals are not kept on site, and will need to be shipped from Mexico.
