Front Wheels Vibrate While Braking

When you apply the brakes, does your steering wheel vibrate left and right or you feel vibrating coming from the front end? This is actually a common problem with the GTO, which can be easily fixed.

Radius Rod BushingsThe factory radius rod bushings are extremely soft and fluid filled. The result is excessive suspension movement and vibrating pedal feel upon braking. The factory bushings prematurely wear, which may also cause your tire alignment to constantly be off and possibly cause the tire to rub on the front strut while turning.

Replacing the radius rod bushings is a must for all 2004-2006 GTO owners. This can easily be done by yourself with fairly simple tools.
