I'm on CORN YO!

Default power steering

I will post this in the RMIC first. This is a real thread with real problems. They story is real as far as I can convey it properly with my limited vocabulary and education.


I replaced my PS pump before SEMA a couple years ago because it was starting to make noise and I didn't want it to get to Vegas and have it fail, considering the cost of a new pump.

About 2 months ago I would get intermittent loss of PS when turning, to the point of the steering wheel almost jerking out of my hand. One hand on the steering wheel and the other getting ready to shift coming out of a corner.

I pulled over and there is a considerable amount of air bubbles in my reservoir. I put hose clamps on all the rubber hoses thinking maybe it was sucking air on the vacuum side or something like that. The problem is getting considerably worse, what use to only happen once or twice in the first couple months now happens when ever I want.

There aren't any leaks anywhere and I check it every time I drive it. I am about to spend money and replace the low pressure hose and the pump again but thought I would ask around and see if I have missed anything.

Help me not spend my turbo money again fixing my car and help me solve my problem.

and for those of you who can't read.

a common problem is the washers on the hard lines. i hardly turned one of the bolts once, literally 1/4 turn, then back tight again. and that made them suck in air. once those washers were replaced and the system rebled, it worked fine again.

I will buy new crush washers and rebleed. Since the pump doesn't make niose I assume the pump isn't going out. I will buy a new low pressure feed hose and replace that as well. I wanted to change that hose when I replaced my pump becuase it was hard as rock, but had to order it and I didn't have the time.

back to the drawing board. I got to work and it started doing it again. I assumed the low fluid in my right light would have caused it. I was wrong.

NEED MORE HELP.

Bring it by the shop! I have an install and Jesse has a tune later on Saturday. Ill be there from 9am to about 4pm. We can try manually bleeding it with the tires off the ground and check for leaks of any kind to make it easier. If the pump isn't growling then its a pressure issue (obviously). It has sometimes taken me hours and hours to bleed power steering fluid after pump, rack, and bushing installs. Its worth a try, right?!

I just ordered new rubber hoses, I will wait until they show replace both the return hose and the feed hose, new fluid and bleed it again. If it doesn't work I will go to plan B. It sucks air from somewhere that's for sure.

The weird thing is the bubbles are super super tiny. I assume that the hole is small enough to let air in when under high rev's but no big enough to leak from just sitting.

I might order a water pump, stat and do a bunch of maint stuff all at the same time.

I will let you know next week and might bring it over to the shop then.

pm'd, there's a thead that helped me with this, it's very likely the oring that seals the return hose connection. unscrew that plastic/metal piece and take a look, it should be round (duh) but when i pulled mine it had degraded to a square cross section and was hard as a rock.

also the return lines do get brittle and though not enough to leak out fluid they do leak in air. with just replacing the clamps many people fix the problem.

on a side note the 20g-xt is in, and five0 will be getting a call from me today about their 1200cc sidefeeds corn juice is just around the corner

I had the jerkyness problem when I would do back to back runs when auto x ing. I switched the fluid to a high quality atf and problem when away.

but it sounds like the O ring replacement might be for you.

I was also about to suggest the top o-ring. I had exact same symptoms. O-ring fixed me! Just be sure to get the right size by either Getting it from the dealer or taking the old one to Checker with you. They've got a great selection of individual o-rings.

Ok so I just went out and played with it for a few mins, and am pretty sure it's the pump

my next question would be how difficult is it to swap them out? is it pretty easy to drain the old fluid?

jon don't do the pump first. get some hose clamps and replace all those pinch crap ones. If that doesn't clear it up. Buy new hoses, I am sure yours are old and hard as a rock (TWSS) THEN if it still makes noise replace the pump.

You will still use your new hoses and clamps. but hoses and clamps = $60 an da pump =$260
