Rebuild my PS control valve?

Cupid · Apr 5, 2006

I anticipate having to rebuild my power steering control valve. (Don't want to pay over 2 bills for a remanufactured one.

I want to use this kit from Mustangs Unlimited.

Has anybody had problems rebuilding their own? Are there any special tools required?

why do you think it needs rebuilding?

stanger53 · Apr 5, 2006

No, it doesn't really require any special tools, but there may be parts that need replacing that aren't in the kit, the spool valve may need machining, etc.

The kit also doesn't come with replacement hose seats, so you aren't doing a thorough rebuild.

A quality rebuild doesn't cost 2 bills, at least not from a reputable shop. You can get a quality rebuild for $85 plus shipping from here http://www.stangerssite.com/controlvalve.html
Since the kit alone is $40, it isn't that much more to get it professionally done with a warranty.

Listen to stanger53, he rebuilt mine and a lot of others.

My anticipation is only based on the fact that the owner said everything was leaking. After test driving the car, I realized that it didn't have power steering. Get this, I checked the fluid level and the PS pump was empty! Unbelievable.... I didn't know it b/c I didn't hear the normal 'whining' sound pumps normally make when fluid is low. The control valve looked like it was leaking as well as the PS pump. I'll replace the pump for 50 bones, but honestly, i'm not 100% positive the control valve is faulty. You guys tell me....does the control valve normally go bad if it hasn't been fed fluid for an extended period of time?

You are right. $85 isn't that bad. What's the turn around time on stangerssite's rebuilds?

Go with the $85 rebuild. I bought the $50 kit, rebuilt mine, only to have it NOT work when I installed it on the car. By that time I was too busy to mess with it so I got a good rebuilt one from Napa for about $100. It's just not worth the time and trouble to rebuild in my opinion unless you really know what you are doing.

replace the pump and clean it all up and see what else leaks. It may be fine, being empty shouldn't hurt the valve.

You probably just have hoses leaking at the valve. Mine has run dry several times with no harm.

If you end up doping it yourself make sure there are no burrs on the valve spool. If there are burrs on it the valve will stick and the control valve will not work properly (no assist, assist in one direction only, intermittent assist). It's no fun, believe me.....
