My blazer has been driving like crap for a while now and slowly getting worse. It would shoot to the left side of the road if you let go of the wheel and when you braked it would shoot to the right of the road. I got sick of it. This weekend I replaced the gear box, tie rod ends, and calipers. Now she drives on the straight and narrow. Its hard to explain the feeling when you take your hand off the wheel, aply the brakes and the truck stops in a striaght line. Its like a whole new truck. Also I had bought a new throttle cable about two years ago and I just now put it in. I guess the old one had some slack in it, because I'm getting alot more power out of my truck. I don't think the old one was opening the throttle all the way. I just had to share another mechanical triumph. It sure feels good. Thanks for your time.
