Subject: DECREASE IN STRUCTURAL RIGIDITY
   Date: (none)

For the past two months I have noted  what appears to be a significant
decrease in structural rigidity in the front section of the car.  This is most
apparent when going over small bumps with significant stering wheel shake and
vibration of the front end of the car (i.e. cowl shake).  My Miata 
has about 10,000 miles on it and it has never been driven over potholed 
streets.  About 5 months ago I had my 4 wheels aligned and the Mazda dealer 
told me that the passenger side tie rod (stabilizer control link) was bent.  
This was replaced under warantee.  After I noted this shake problem I looked 
under the car and found the tie rod on the other side slightly bent.  
I don't think that this is the reason for apparent decrease in structural 
rigidity I have noticed but could indicate that other components of the
car (rigid aluminum power frame for example) has sustained some kind of 
damage.  Has anyone else noted a significant change in the rigidity of the 
car?  If so, what caused it or what do you think could be causing the 
problem?  I am not sure that I trust the Dealership to resolve the problem 
so any help would be appreciated.

P.S.  The car is still under warantee.
