My 98.5 A4Q is due for oil and filter change and NYS inspection (plus
replacement of snow tires with summer tires) next month, and in the
last couple of weeks, I've noticed at highway speeds a slight bounce
in the front end. Some times it's more obvious than others, depending
on the road surface, but basically the car doesn't feel like it's
holding its nose down on the road. It doesn't shudder, it just gently
bounces, almost like a Cadillac. What might this be? Do I need new
shocks, new struts? Both front tie rod ends were replaced last May,
and a complete alignment was done by the Audi specialist garage.

There also seems to be a grinding feeling coming from the front that I
can't describe well, and this is noticeable at lower speeds. The
right front corner control arms were replaced last May, too.

Suggestions for what the problem(s) might be? The car has 97,000
miles on it, and I love it, with its still smooth original clutch.
