Factory power steering box leak

[broncobuddha]

Don't have an in vehicle pic but here's a stock photo.

Edit: added a pic of mine.

It's leaking out of this hole. Quite a bit.

So if there's a leak here, what does this indicate? A bad seal internally or something right there?

At first, I didn't realize these had weep holes and I was thinking I'll just butt weld that shut.

However, since it's there on purpose and serves a purpose, I decided that would be bad. I'm just not sure what a leak here indicates.

That's the hole for getting the snap ring out. The end seal needs to be replaced.

No room to do it there. Must have been my square body that I did in place.

As stated, the hole is to assist with getting the snap ring out. There's an aluminum cap at the end of the box with an o-ring seal on it. Remove the snap ring, turn the input shaft to push the cap out, replace the seal.

Ok. So typically that hole is for what, an awl/punch to release the ring? I've never taken the front off of one of those.

However, when it rains, it pours. During my testing/searching for the leak, I noticed the box flexing under load. From left to right etc.... Turns out there's a stress or hairline crack in the $&#*$# frame by the rear flange bolt of the box. Sigh.... so, the box may still need to come out regardless so I can asses the frame and see what I can do there.

Looks like I have bracket options from multiple places to handle that. So, the box is coming out and I'll try my hand at the end seal and I'll add the bracket when it goes back in.

What is the technical name of this seal at the front?

Punch, awl, Allen wrench etc just whatever you have that is stiff enough to push it out. Walk it back in when done. When you put it back together make sure you keep the end of the ring close to the hole for the next time. It will make sense when you get there.

Sounds like you found the options for the frame fix.

Good luck

I've been searching and looking at videos and I see how the snap ring and cap work now.

The question now is are we talking about the oring on the back of the cap that I'm replacing or do I need to actually do that first teflon seal and oring on the piston?

The o ring on the cap is the only place that can leak to the outside.

What else you want to do is up to you.

Perfect, that's what I was looking for.

Welp, got it out and all of the grime cleaned off. Got the end cap off and am waiting on seals to get here. Hope this takes care of it. If so it'll save me a near $500 outlay for a replacement.

I am having this issue of a leaky PS pump. Was it the O-Ring on the cap or bottom seals?
