Power steering issues

[smoo]

Gday there. The other day in my AU 4.0, I heard a strange noise relative to revs and load while in traffic... got home and the p/s resevor was bone dry. Topped her up then chucked her on the hoist the next day. Looks as though theres a leak at the sensor in a ofa place between the rack and cross member. Since I have to drive 700km on Sunday and Ford dealers (parts) arent open tomorrow (already tried repco, nothing), can a temp fix be done... such as silicon up the switch? Or thread sealant?

What would cause the leak? An O ring?

While I'm at it I also did a search on this topic and found that to do the seals in the p/s rack 'special' tools are needed. What sort of tools are these... Ford factory ones?

Also does anyone have an exploded illustrations of the steering rack?

Any help appreciated.

Cheers.
