Leaking power steering gear box?

[ClarkDart70]

I have power steering fluid coming out of the power steering box on my 70. Its in a weird location howevere... its coming out where the steering shaft coming in from the column. Anyone experience this or know of a seal kit that can be installed? Everything works well.... it just appears to leak.

It's probably the high-pressure hose that's actually leaking ; may also be the "o"-rings / seals in the pump's spool valve housing .

It's actually cheaper to buy a reman steering box than it is to buy the "o"-ring & seal kit !
Remember to back-off on power steering boost vis-a-vis shimming the high-pressure hose away from its inlet .

Yeah there is a shaft seal there. If the shaft is worn enough the new seal will only slow the leak. Turn the input shaft and see how much linear movement there is. If the shaft appears to run in and out of the seal a gear box rebuild is needed. There is a acceptable tolerance for that movement but I forget, 1/16 inch maybe.
