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.

In a 2004 Chevy Blazer, 20000 miles. 4 wheel drive front differential actuator failed to engage. Upon inspection it was determined that the actuator had corroded to the point that it need to be replaced. The first replacement part also failed shortly after being connected and a third part needed to be ordered. All replacements were conducted by manufacturer.
