What am I missing?
I just got all my power steering stuff hooked, but it's not working. The pump is making grinding noise like it's a bad pump & the PS fluid is all foamy(air bubbles).
Does this sound like a bad pump or is there something I'm supposed to do to "prime" the gearbox with fluid? The gearbox & pump were both used when I got them. The pump was supposedly pulled off a running truck. I need input on this. I have a hard time stopping on a project before it's done & pulling that PS pump is a PITA. Mike |

Pumps mounted in the "with A/C" location wont bleed the air out by themselves like other models will. The pump is actually level with the gear which means you will need to force some of the air out of the gear manually. Try turning the wheels side to side with the engine off, then start periodicaly to see if it will pick up fluid or not. Dont run it to long as this will damage the pump.
This is somewhat dangerous but try cracking the pressure line loose just a bit, enough to cause a small leak. then start it up and work the wheel from side to side. Good luck with it! |

Jack up the front end and turn the wheels all the way to right and all the way to the left a few times ( do not hold it all way over) with engine running should get the air out.

When you first hook one up they always do that. What I do is with the truck idleing and the pump full turn the wheels back and forth each way as far as you can turn it about 20 times then turn it off and check the fluid level and add as needed. Then take it for about a 15 minute drive and stop and check fluid again and so on it will finally work all the air out.

do what Denny and Tim are telling you. I have seen some of these clear up in 15 minutes of turning the wheel lock to lock and others have taken what seems to be 15 days to finally be burped. Take your time and the bubbles will work their way out.
