Well...I'm WAITING!
Starting to think the Firestone Complete Auto Care I use must have lost a few of their good mechanics or something since the last time I was there. Truck has been there since last Wednesday. They got to it initially on Saturday. I called them yesterday. They said the initial fix didn't work. STILL waiting on an update from them. The last couple of times I've used them, they were prompt, and always called to update me on what was happening.
