[Shotimes] 91 SHO hard to steer

[don donelson]

My screen name ( ya once a sho lover always a sho lover ) on the 
stangsunleashed sight is 1badsho

So had a guy post to me about his 91 SHO that is giving him steering 
problems ..  I will copy and paste his remarks :

SHO...not too many people know what that car was all about. I have a '91 SHO 
and absolutely love the car as my daily driver, however, I've encountered an 
issue I want to bounce off you. Return to center from a left turn is 
difficult and is accompanied with a high pitched whine, add power and it 
becomes increasingly difficult and down right dangerous. This has been a 
lingering issue for a couple of years now (I only drive it during summer ~8 
- 10K per year). I was a Ford tech for 10+ years and worry it's transmission 
related. Changes to date include:

K&N
Borla
Tokico Struts
Eibach Springs
Outter Tie Rods
Axles (loose CVs?) this was a long shot but the boots were cracked anyway.

Next thought...differential bearings?



I replaced the half shafts last year, mainly because the boots were 
cracking/torn and the slight possibility of CV issues. I'm wondering if the 
difference in turning radius is causing an issue? I also forgot to mention 
the wheel must be physically brought back to center when under load and 
there is a definite binding about 1/2 turn back. This is certainly not 
normal and is only noticeable when turning left. Again, add power (1/2 tip 
in+) and you have to pull the wheel back or get out of the throttle. This 
does not seem to be a power steering issue in my mind. There are no signs of 
leaks and why the whine and why would the condition be tied to engine RPM? 
Very strange indeed.

Also, I used shims (washers) when installing the struts. Noise and binding 
gone.





My thoughts are a bad pwr steering rack ... if its binding .. thats why your 
having the noise ...

your all thoughts ??
