I pulled my steering gear to change the pitman arm, and when I got it back together and started the truck, the steering wheel moves back and forth on its own. I stopped the truck, topped off the fluid resiviour, and it kept doing it. I sat in the driveway idling turning the wheel lock to lock and it kept doing it after a few minutes. The lines are not switched. I checked that and they will only go one way.

 

Does the system just need more time to purge itself?

Note to self: When you empty your whole power steering system, especially the gear box, It can take upwards of 10-15 minutes of idling in the driveway to completely purge the system and for all weird feelings to go away.

 

Don't panic like I did.

I would've panicked too. You're not alone.

 

Glad to hear it worked out!

Do you know what you're doing or are you looking for some tips? The order in which you do things really makes a difference with this.

Can anyone recommend a source of power-steering pumps that doesn't suck?  I got a reman delco unit from rock auto and it's pretty much dead already.  I also want to add a filter and a cooler when I re-do the pump again.

I have a question to run along with this....

 

What if you put TOO MUCH power steering fluid in the reservoir? Can it cause the system to "purge" the excess by seeping out of perfectly good power steering lines at any possible weak point?

 

I ask because I was getting power steering fluid leaking (only when I was doing something like parallel parking - when I would have to go from one side of the steering lock to the other and back) and it would be dripping some fluid out.

But in general driving... nothing. The level WAS fairly high in the reservoir.. I would venture to say "too high". And now that it's down and registering on the stick in the proper area.. I'm not seeing as much leaking going on.

 

Any ideas from the peanut gallery? Are my lines going bad, or was it just purging excess fluid?

If it's under warranty, AC Delco is great at returns...personally I would just go with them.  There are very few actual manufacturers so unless you are going for a high pressure setup, I would personally just go AC.

 

Where do you plan on plumbing in a filter?

 

Coolers are a great option.  For OEM, you have two setups I have comes across.  The fin setup that mounts right behind the grill and the setup that mounts inside the frame.

 

If you go to the junkyard, you'll find a ton of fin setups on GMT800 trucks and GMT400 1 tons.  The hard part is finding one that isn't rusted badly.

 

Otherwise, OEM on the fin setup is around $100, but you could go cheaper with aftermarket  ($35) and just build your own brackets.

 

Is hydroboost or ram-assist steering in your future?  If it is, you can get a head start by purchasing the right higher pressure steering pump now.

the only way too much fluid would burp out when it heats up is through the cap on the pump, not out of any of the lines. If a line is seeping it's bad, period.

 

I get some p/s fluid burping out of the cap on my track cars when I am pushing them hard, especially my `97 cobra which has hydroboost (p/s pump powered) brakes. Never any signs of leaking at any point on the lines.

Yeah.. I was afraid of that.

Alrighty.. thanks for the info! :)

I use two (2) p/s coolers to protect my investment as mentioned before heat can cause overflow and at the p/s pump it can melt the impellers.

I added an aftermarket cooler. It's about 5"x5" fin and plate. I paid about $30 for the whole kit. Been running it almost a year now. I have it plumbed on the return side of the steering system. It's mounted in front of the AC condenser, bottom corner, driver side.

 

And to follow up on this, I am still running the same AC delco pump. Turns out it had lost the "bleed" or "prime" on its own and was only acting like it was dead. It might of had something to do with the cooler. I read somewhere If you mount the cooler too high above the pump It could happen. But It's been good for months now. Its proven to be a good strong pump when it's bled right..

When an aux cooler is mounted higher than fill port on p/s pump there is drain back when vehicle is not running which then drains out of the fill cap vent then on a restart the remaining p/s fluid is pumped into the cooler and the same thing happens over and over until such time as it drains all the fluid........................................common problem.
