Had the front axles replaced about 4 months ago and I can feel the vibration starting through the steering wheel and gas pedal. I dread taking it back again because they kept in ten days last time. I guess i'll wait till it really gets bad so I don't have to drive the repair guy all over the place trying to duplicate the problem again. On a good note I just averaged 39 mpg on a 1000 mi trip fully loaded.
