[s-cars] Suspension trouble

[Tom Green]

Igor, Ivan, and others that see this message, greetings.

Check the attachment points for the steering rack and the steering  
damper.
There have been some loose bolts and some cracked fittings.  If a  
friendly
helper can turn the wheel to initiate the noise while you get closer  
to the
source, perhaps you can isolate the problem area.

Rather than eliminate parts that I have just replaced from the  
troubleshooting,
I tend to recheck all those things I have done as more likely  
culprits.  :-)  Of
course, Igor, your legendary thoroughness makes that process less  
necessary.

Others have reported success fitting 5K ball joint dust caps as the  
last ones
available as individual parts.  I have no experience there and am  
puzzled
about the cause.

Tom

List,

I'm about ready to overhaul suspension on my 93' UrS4

Currently car has 133k miles and PO installed Bilstein SP + H&R at  
around 75k.
My feeling is that shocks already done. Also, I don't like current  
stiffness.

1. To me it's too harsh and I don't see this benefiting handling. It  
almost feels like wheels disconnect from the pavement on a
bumpy road when I go into tight turns.

However, I like ride height and hate to raise a car since it will  
look silly with my 17" RS4 style wheels.

So... What do you suggest for suspension components? I like firm but  
soft ride. Not too much body roll but without go kart feeling.
Different springs? Shocks?

2.  What is the symptoms of bad steering dumpner? My car feels like  
it wants to turn left.

3. I have exactly same clunk as Igor Kessel described few days ago.  
Left turn, slight acceleration - sounds like CV Joint popping out :)

4. Car pulls hard to the left on hard braking. It's got to be  
suspension as I rebuilt rear calipers and replaced front/rear discs/ 
pads. Wear is normal, everything working ok.


I'm planning to go ahead and replace all rubber pieces I find in  
suspension + shocks + tie rod ends + rear links.

Any advices/suggestions?

Thanks,
Ivan
