First off, I apologise if I ruffle your feathers. Second, It seems that you're being
a bit too critical of an 11 year old car that has had rebuilding in one area. Your
problem sounds to be coming from some rotating mass in the vehicle (bearing,rotor,
tire, wheel, driveline....,) if things are as you describe. NVH (noise, vibration,
harshnass) is terribly difficult on older vehicles. You describe the symptoms as
"slight and occasional". My definition of "slight" is : I have to really be looking
for it", and occasional is:just now and then". What are yours? As a car ages, there is
no way to "repair" some of the "sometimes" problems with it without major expense.
How do you know the problem is "front end"? What you describe is usually an
indication of rear driveline concerns. (Universal joints, pinion bearing,etc). It
could be caused by slightly worn bushings in the rear trailing arm bushings causing
oscillations in the driveshaft due to slightly worn universal joints, etc.... under
One thing I've noticed through the years is that: People notice problems with their
cars after work is performed. Little things may have been unnoticed before a repair,
but after you shell out big$$$ you are looking much closer for problems and unrelated
concerns become apparent. Thus "You just fixed my xxxxx, and now yyyyy is happening".
How many miles on your T-bird?
Why did you have all of the font end work done in the first place?
