my car, 1998 ford explorer 82k miles , recently very vibrating when I run on a slightly uneven road. It becomes shaking on uneven freeway at speed 60 miles. I have did agliment, tire rotation and tire balance but the problem still stays the same. I was wondering if something is wrong with the suspension system. If so, where can I bring it in to fix the problem? Is it good idea to take it to the ford service (dealer)?
Thanks in advance.
