Last weekend I installed the seal until the seal bottomed in the housing, then pushed the c clip in until it bottomed out on a second shoulder. The speedometer gear was snug in the housing and a little stiff to turn. Today I have a large red puddle under the car. The leak is definitely the inner seal. Looks like I get to try this again. Does anyone know what tool C-4004 looks like (reference the FSM above), or at least how long the tool is? Trying to nail down the seal insertion depth so I don't have to do this a third time.
