My PS pump is leaking from behind the pump. Should I just replace the O-Ring or should I do the seal as well?

Paul H.

I would do it all.

I am trying to avoid removing the pump, as I need the truck on a daily basis. Also, I do not want to get over my head rebuilding the entire pump.

they also have your pump, and hoses, but the pump is 350

That presents a problem...

I would just swap a good dry box in....much quicker and easier than rebuilding. A complete rebuild kit (which is what you should get if you are going through all of the trouble) is around 60 or 70 bucks I think. Rebuilding a box is not that hard....but its not the easiest thing either... Dry boxes go for around 100 bucks all day long

I had a whole post typed out & lost it when I went to find & copy the link lol

I just rebuilt mine for the cost of a $33 kit shipped to my door (Edit:that's $24.26 for the kit & $8.99 shipping). Either way you go rebuild or swap out; you'll have to take it out of the truck. You can't really swap out seals or O-rings with it still in the truck. You'll end up causing more problems than if you just took it out.

My advice is rebuild it for $30, it took me three hours start to finish including a trip to the parts store for a new, slightly shorter belt. Unless that extra $70 - $100 isn't an issue then, go ahead and swap it out for a used one & rebuild your old one while you have it out....but you'll kick yourself for not rebuilding it. It's simple.

DOH! my bad....i thought we were talking about the steering box ...not the pump!

I have good steering pumps used if you want one.... they are around 40 to 50 bucks SHIPPED.

Throw some powersteering fluid with stop leak in there and it will stop the leak.

Until it eats the seals. Our systems take ATF not power steering fluid!

PSF means a quick and certain death for your PS pump. If you have done that, don't try to rebuild - get a replacement. Before taking the old one off, be sure to completely flush the system.

Yes, in my experience, using power steering fluid instead of ATF IS that big a deal.

jason191918

Maybe thats why mine leaks...

I ordered a reman today. Gonne flush the whole system and use atf from now on. thanks TC

A rebuild for $30 would have been a helluva lot cheaper & it probably would've taken about the same length of time for the kit to arrive. I think I got mine in two days. But to each his own, if you didn't feel confident taking one apart you made the right call....& TC is dead on; never never never use power steering fluid. My wife proved that point to me.

So I started to change out pumps tonight. I got all the lines and bolts out, but the pulley is not off yet. I actually searched and got a few hints as to how to remove the pulley, but that's a job for tomorrow. My only question at this point is, is there a right and wrong way for the vacuum lines?

Brenjen

Those vacuum lines aren't even essential; heck I broke one of the darned plastic nipples when I was putting the rebuilt pump back in my 4Runner. I just plugged them off, it's for the idle up when the pump is at full steer, I never leave my pump at full steer for more than a second & then only so I can see how much I have left & back out of it (if that makes sense) so I don't miss it.

As far as I know they are location specific but it shouldn't be hard to swap if you get it backwards.

Thank you for the response.
