ctis leaks down in front

[Little General]

After a week my front tyres leak from 35 dowm to 10. If I unhook the lines at the front wheels the tyres stay up. I soaped the lines under the truck and hood and found nothing. Any ideas? BTW I just replaced the spindle out seal and it don't leak.

well... a good bottle of windex should help you here... you should see the bubbles where its coming out from... you have a spindle seal on either side of the truck that could be leaking.... plus any fitting... start spraying and see where you see the bubbles.....

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.

Thanks Humtech, it was the seal in the steering cover. From now on whenever I replace any seals in the gearhubs I am going to replace them all.
