My fuel pump gave out ( I've had no other problems with my blazer before this, it ran just beautifully) recently and I had it replaced.

  We have the same problem. Had oil changed in rear differential and it seemed to help for a couple of months. Next is transmission service. It feels like the jolly green giant just grabs the rear of my blazer and yanks real quick. That is the only way I can describe it. Good luck with that and if I find anything else out I will post for you.

Don't faint, they are pretty cheap and easy to find. Unlike the front calipers, the rear are made of aluminum. When you push the piston back in to accomodate the new, ... Read More
