ctis leaks down in front

[HUMTECH]

What do you mean by the spindle out seal? The geared hub has a geared hub output seal (oil seal) an input seal (also an oil seal) and inside the steering arm cover is a ctis spindle seal which is the only seal for the ctis in the hub. The seal itself is about the size of a quarter. To check if it is leaking remove the geared hub vent line and check for air escaping from there using water and liquid soap mix or like phazer said even windex. any thing that will bubble up. If you just replaced the output seal it is very likely you damaged the ctis seal reinstalling the steering arm cover.
