I am having issues with my 03 2wd outlander shaking when I accelerate at higher speeds. It is not very noticeable at lower speeds and even at higher speeds it only happens when I am on the throttle. Firestone told me I had bad outer tie rods so I replaced then and got an alignment, but the shake is still very noticeable. Thank you for your help in advance.

 

Step one is to have the tires and wheels examined/balanced by a place that has one of these:
