Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Developed a strange knocking that sounds like a bad rod almost, no check engine light, no loss in performance just a very annoying knocking. Worst when it's cold in between 2-3, 500 RPM's. Progressively got worse over time, I got rid of the truck before I had to buy an engine.
