You are going to get a lot of varied answers to this question.  I'll
assume you have the canadian slicers.

The drivetrain is similar between 91 and 92.  I lived with this problem
for close to 4 years.  In that 4 year timespan, besides the usual balance
the tires deal, here's a list of things that changed on my car.

I had the knuckles changed as part of the 96 brake upgrade.  This gave me
new wheel bearings.  No change.

Both half-shafts were replaced, including the link shaft assembly.  The
total of all these changes made a big impact but did not complete solve
the 70 MPH issue.

Replaced inner tie rods to remove some play in the wheels.  Needed this go
get a proper alignment.  No change to vibration at 70.

Bought new wheel/tire package upgrade.  This nailed it!  It is a real
pleasure to drive the car now, so I know what you are going through.

Now, what this proved to me is one of two things happened on the original
slicers.  Either one or more wheels has a problem, or one or more tires
has broken internal belt.  This latter thing can happen with radials.  I
was able to quiet things down with the slicers by moving a suspect tire
(that was virtually brand new mind you) to the rear of the car.  So if you
rotate your tires front to back and can feel a difference, that might be
the area to investigate.
