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.

2004 Jeep Wrangler Owner Comments

problem #1

While moving rocks in my yard, I put the transfer case in low and locked the axles, both front and rear. The front driver side U-joint exploded, damaging the inner and outer axles. The vehicle was undrivable. I do failure assessment for my work and have determined incorrect heat treating of the critical drive train components to be suspect. This is suppose to be a heavy duty vehicle. Moving rocks is hardly heavy duty. There are also a lot of "replacement" axles available on the aftermarket that state they are "more" heavy duty than stock. A neighbor down the street experienced the same failure prior to me. My vehicle missed the warranty by 2,700 miles but is 2 years under. Repairs are expected to be $1,000 plus labor.
