Hi Everyone,

I have been having steering problems with my 67 convertible since I purchased
it two years ago. The recent flurry of advice to others on the list with
similar problems have been very helpful. I have followed along religiously
making the changes/repairs as suggested and there has been a huge improvement.
I have replaced/rebuilt all the steering components and replaced all the
suspension. Here's what’s now happening:

At start up the power steering works beautifully. Very easy to turn. At
highway speeds and above the car tracks perfectly. After 20 minutes on the
highway though, the car gets really "squirrely". The front end starts to dart
around the lane. At slower speeds it feels as though I have lost all PS
function. Let the car sit for 45 minutes, and its perfect once more until
driven for 20 continuous minutes. My only conclusion is that I'm overheating
my PS fluid - is this possible?? I have stainless steel headers and the PS
lines run within 3/4" of the middle tubes. Would putting heat shields around
the lines help?? Should I just relocate the lines?? I have FOUR vintage
Mustang/Shelby shops within 12 miles of my home and they have been no help -
but they're good at scratching their heads and asking for $95 an hour.

Any and all advice is greatly appreciated!! Thanks.

Craig

I don't know, my steering lines run very close to my headers as well, but I
don't have any problems with them, maybe because I did install a heat
shield. Not because of overheating, but because the rubber hoses were
melting.

I wrapped the tubes closest to the steering lines with fiberglass, and then
put sheet aluminum around them, fastening them with stainless steel hose
clamps.

Your problem sounds more like a bad control valve though. doesn't sound
like the box, it's purely mechanical and doesn't get affected much by heat.
I doubt it is the power cylinder either, just because of its nature, it
sounds like the control valve.

Good luck!

Do you have a power steering cooler?
