I have another question about my girlfriend's 2003 Montana. About a month ago she got an alignment and rotate and balance cause it was pulling and bouncing really bad. They said they replaced a tie rod end as well. That seemed to help things but now it is back to bouncing really bad at highway speeds. It's bad enough that my girlfriend is afraid to drive it. I jacked it up and checked the wheel bearings and tie rod ends for play by trying to move the tire around. It seemed reasonably tight. I did notice that the tie rod end and the ball joint on the driver's side both have tears in their rubber boots. Is this bouncing most likely due to bad struts, bad balancing job, or something else? Any suggestions and things I should check would be appreciated.
