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 GMC Sierra 1500 Owner Comments

problem #1

May 182012

Sierra 1500 SLE 4.8L

  • Automatic transmission
  • 147,500 miles


Okay, 1st, I bought the truck used w/ 112,000 mi's in 08. It is now 5-22-12 & i have approx 150,000 mi's.

After having the 3rd transfer case put in this truck, 2 weeks later, I'm hearing grumbling noises. I drive w/ the mechanic, & he hears it. He puts it on the lift & points out some loose prts in the u-joint. He says lets do all the u-joints while were at it. I pick up the truck, & at

25mph, the truck is making a loud vibration noise. I'm amazed the mechanic didn't drive the vehicle after the so called $560.00 repair. Now I'm w/out vehicle for 3 more days, & mechanic is going to replace a rear yoke carrier for drivelines. he doesn't know if this will fix problem. My checkbook is taking a huge hit at this repair place, & i'm not sure if all the repairs done were necessary. Someone please guide me out of this one. I will leave other complaints about the previous repairs.
