I have a 92'940T that continues to shake no matter what I seem to do to rectify the situation. The following is what has been replaced/done: tires rotated & rebalanced, front end aligned, strut rod bushings replaced, sway bars upgraded w/new bushings, Tie rod ends/ball joints inspected and found good & tight, upgraded strunts & springs, tires inspected for even wear pattern - confirmed.....Additional symptoms, usually at its worst @60-65mph, practically disappears when going around right turns/curves, but comes back as soon as wheel turned back straight, and lastly when car is first driven each day (when cold)as car is driven through curves & wheel is turned, there will be a sudden/slight jerk of the wheel in the direction of the curve, either right turn or left, but once the car warms up this is no longer a problem...could this be a steering rack malfunction.....Thanx....Severely puzzled
