=================
Took the rack out of the car today to put in new bushings and this is
what I found. PO had filled a hole in a boot with silicone. Didn't do a
very good job. That side had a bad inner tie rod joint. so I've decided
to do both inners and both boots.
ALSO found that the end near the steering screw does the sideways
motion when you turn the steering screw back and forth. This tells me
that the bushing is bad inside the rack on that end. Before I take the
rack apart to make or buy and install new bushings, I would like to here
from others who have been there. Walt, you been there? Or is this
some
kind of magic voodoo stuff?

==================
We have two rebuild kits left from PCNA stock. This is the kit they
used to
use when they did their own rebuilds. The part number is 928.347.999.99
and
I have only two of them left at $40 each. They are labeled as being for
85-90 Porsche 928.
We do not rebuild steering racks in-house, so I do not know if this kit will
work with earlier racks. It's basically a bag with about 20-30 o-rings,
seals, etc. I've sold over 25 of the kits, so someone out there must have
attempted the rebuild!
Hope you're all having a great weekend...sure is nice here in No. Cal!

========================
PS fluid is leaking quickly when car is running from steering rack
driver's side boot - checked Nichols and slyjay sites, doesn't sound
promising - sounds like rack is shot.
Any chance that there is supposed to be fluid in the boot and I just have
to replace the boot? (yeah, I didn't think so...)
Any alternatives to having rack replaced?
Any way to just replace seals?
Any recommendations for where to take it in Los Angeles area?
How much should getting rack replaced cost?
Thanks in advance for your help - you guys are great.

What? You had a question????? It's like talking to a bunch of hyperactive kids,
isn't it?
There are a bunch of replaceable seals inside the steering rack. I had my old
one completely
apart a few years ago, but by the time I was done it leaked more than when I
started, because
I had never replaced seals before, and I didn't do the work correctly. But if
you want to give
it a go, all you need is a BIG wrench to unscrew the ends of the rack, take it
apart, pull off
the various seals, go to your local seal and bearing store for replacements, and
reassemble
it. You might want to replace the pilot bearing inside there while you are at
it.
The alternative is to call 928 International, who is close by you, for a rebuilt
steering
rack.

Hey guys,
Racks aren't always fixed by seal replacement and rebuilt racks aren't
always well done. I have been using a used s4 rack in my 79 for 4 years
without any incidents. At the time I bought it for about $225 I think. I
used the 32mm bicycle head set wrench to get the inner tie rods off.
There are some tightly machined bushings inside the rack that have to be
right. If there is slop in the rack bushings it will just tear up new seals
and o-rings.

>I have just taken my 88 928 s4 in for a warrant of fitness which we have to do every 6 month here in New Zealand to find it has failed due to excessive play in the steering rack. This means I either have to put new bushes and seals into it or fit a reconditioned one. Strangely enough the rack is not leaking.
>Can anyone out there tell me the part numbers I need to order to rebuild the rack.
In the USA, neither Porsche nor ZF support rebuilding the rack any more.
The seal kit, formerly available from Porsche, was P/N 928.347.999.99.
It contained seals only - no bushings. I have been told that the
bushings are available from a ZF service depot, but we can't get them.
We can furnish ZF-rebuilt rack units, or we can furnish rebuilt units
by Griffith. I would suggest that you check on bushes from a ZF
supplier locally. Of course, I have no way of knowing whether such a
supplier even exists, nor whether they will sell to you - but that
would be my suggested approach.
Rebuilding a rack is not a trivial task, and it is what we in aerospace
would call a "safety of flight" operation, so don't take it lightly.
Sorry that I can't be of more help.
