I have a 2001 Chevy express and when I’m accelerating at higher speeds like from 70-90 mph I hear a vibration oscillating on and off ever 1-2 seconds what do you guys think it could be 🤔 thanks for you knowledge beforehand,thanks ---

Is it 4 wheel drive or rear wheel drive? Either way my first thought is U-joints, second is front hubs. ---

If you don’t feel the vibration in the steering wheel, more likely this is coming from the transmission, driveshaft, or rear wheels. If it is worse during acceleration, the first two are the prime suspects. If it vibrates at speed even with no acceleration, or when coasting down through that speed, something to do w/the rear wheels. ---

I hooked a scan tool up to it and it pulled a crankshaft sensor code, a camshaft sensor code, and something with the timing ---
