but as I explained to Josh today, tire vibration issues are there and stay there, they dont come and go away. These pacificas are some of the most money gobbling cars on the road. In Josh's case the vibration was coming from his rear tires.. one had 12 psi one had 18. a tire perfectly balanced but not properly inflated will develop a shake.
As far as the alignment goes LF toe was off .06 degrees which could be any number of things upto and including what way the tie rod was pointing when the last guy set the alignment. At the end of each alignment adjustment, you are to jounce the front end or equalize the rotational socket of the joint. this helps set everything level for an accurate measurement.
josh's front and rear ends are tight as tight can be. As were Eli's last time I checked them.
I've seen intermittent vibrations from any of the following
front cv joints/axles
driveshafts/ carrier bearings
bad spot in a shock or strut.
The only thing to do is rule out the tires and wheels first because thats the cheapest/ easiest thing to do.
I'm not sure if Josh is still getting any vibration after today, but Eli you're welcome to send your wife back up and we'll check the balance on the tires.
