An EXTREMELY high percentage of vibration complaints turn out to be wheel/tire problems, probably over 90%.

It's important to understand that vibration will only be CAUSED by rotating mass. Loose or worn suspension parts will not CAUSE vibration, but will AMPLIFY the vibration.

Whenever you have worn suspension parts, you should certainly see to it, but don't expect that alone to eliminate vibration. If it decreases the vibration, you are only covering up the true source of vibration, not correcting it.

It is not uncommon at all to balance, rebalance...... tires until you're blue in the face only to find that you have a tire with a broken belt or other malady. The 9700 can determine this.

Good luck,
