Thanks for the replies, fellas.
This is a follow-up to my post from last week. As was suggested, I
removed enough of the power steering fluid last week in order to
refill with Lucas' Power Steering Stop Leak formula, bled the rack
with the front wheels elevated and drove the car around the block a
few times and all seemed well.
After going out of town for a few days, I started the car yesterday
and drove around town. Initially, I thought all was well, but as I
drove the car on a few errands, the pump started getting louder and
louder. I parked the car last night and when it was started this
morning, the pump was very loud and I could see that the fluid in the
reservoir was foamy and frothy. I cut the car off and then had the
foamy fluid overflow the reservoir again and make another mess.
Yesterday, during the errands, I checked the fluid level and it looked
good with no foaming...nice clear fluid at the proper level was in the
Obviously, the system is somehow getting a lot of air entrapped in
it. Is there some way in which air can get into the system other than
a low fluid level? I'm still not seeing any leakage around the rack
boots, etc. I understand that the racks can leak into the boots and
not be obvious on the outside.
At this point, I'm still not certain if it is a rack issue, a pump
issue, or something else. I hate to start throwing parts at the thing
and especially hate the thought of having to swap out the rack as that
looks like I real pain to swap out.
By the way, the reservoir isn't a remotely-located one; it's attached
to the back of the pump.
Stuart, why do you suppose the pump AND rack will need to be replaced
if that rack is bad? Do any of the other power steering components
need to be replaced typically?
Any other suggestions would be appreciated.
