Slant Six Forum :: Power Steering on '70 Dart

SO I have a power steering leak on my '70 Dart Custom. It's got the 225. In reading my Hayne's repair manual, it seems to give me three options for potentially fixing it

1. Replace the 'sector shaft oil seal'
2. Do a 'Valve Body Overhaul'
3. Replace the whole thing.

We really need to get you out of that Haynes manual before you hurt yourself, your wallet and/or your car. Please get a factory service manual at your soonest opportunity. The quality and quantity of information is far, far better.

Are you committed to keeping P/S? I generally find it considerably more hassle than it's worth, and fix it by replacing with nonpower steering!

SO I have a power steering leak on my '70 Dart Custom. It's got the 225. In reading my Hayne's repair manual, it seems to give me three options for potentially fixing it. First off let me say that the leak is coming from the bottom of the Steering gear. Where exactly, I don't know yet, but I can find that out. I think right where the gear meets the pitman arm. Anyway, it seems my three potential fixes are this: 1. Replace the 'sector shaft oil seal' 2. Do a 'Valve Body Overhaul' 3. Replace the whole thing. Can anyone point me in the right direction with that? I figure I should try them in the order I listed them. Any thoughts? Thanks in advance. -KC

The sector shaft oil seal is pretty much the only potential leak point at the bottom area of the box. Are you committed to keeping P/S?

Still, if you know their limitations and know not to believe everything you read in one, they are better than nothing (but not by much). D/W

I went manual on my 70. Man, what a difference. I must have ditched 70lbs or more off the front end, and the effort isn't bad at all, better then the overpower assist.

Years ago the PS box sector shaft seal went bad on my '75 Coronet - the '75 Dodge manual said you could use the special tool (sort of a huge hollow easyout), but also said you could just blow the seal out by removing the retainers, adding fluid, and running the engine and turning the wheel to the stops to build up pressure. It worked like a champ! (Be sure to have a pan to catch the fluid!) My Chiltons didn't list that trick, but the factory manual sure did.
