Attention: TDR Forum Junkies The details:
98 12V 4x4 quadcab automatic with ~200k miles that I've owned for about 3 months. Its always been a CA truck so no serious rust. I've replaced the track bar, tie-rod ends, front shocks (including shock bolts), steering box, steering shaft, steering stabilizer, and front sway bar links all within the last 1000 miles.
The problem:
My truck has a few different clunks, rattles and vibrations but the one that I'm trying to resolve can best be described as a metal on metal vibration / rattle. It only happens when I'm stopped in gear with the brake on and the wheels straight forward. If I turn the wheel to either side while stopped, the vibration / rattle stops. I believe it stops because the engine smooths out a bit when the wheel is turned and therefore reduces the amount of shaking going on under the hood. The noise is fairly loud and sounds like its coming from directly beneath the driver's floor board. Outside the truck, the noise is amplified by the pickup bed and can be heard underneath the driver's floorboard but is difficult to hear from other locations. The vibration / rattle can be felt, though the noise is significantly more attention grabbing than the feeling.
My exhaust is not contacting anything anywhere and all exhaust clamps / fittings are tight. Nothing in the front end is rubbing or touching. I had a shop check the engine mounts and they said they were fine. My transmission mounts are tight. My pickup bed mounting bolts are tight. My tailgate is not rattling.
Has anyone encountered something like this? I've spent hours underneath the truck prying on things, tightening nuts and bolts, pounding on things, listening for the source, etc. I'm at a complete loss.
