I have a 2000 Silverado 2wd ext Cab SHort Bed this has the 4.3L V8. I have changed the Brake pads all the way around and have changed the rear shocksl. the Rotors are over 20 thousandths out of spec so they will need to be replaced too. The Front Shocks I know need to be replaced as they are factory originals at 94K miles.
At 45mph the truck feels like a tire is out of balance or round (bounces). I took it in yesterday and had all 4 tires balanced and an alignment done. once I did that it didnt improve the ride it made the bounce worse. Any Ideas on what this could be? Truck feels like a bouncing ball. if you tap the bakes it doesnt change it so I think that eleminates the Brake Job that I did...If you speed up it goes away and if you slow down to 40mph it goes away...
