Hello everyone, I'm new to the forum. I recently got a 2018 Silverado 5.3 AWD with around 107k miles. Now for my problem. When I start off, I feel a jolt/vibration on the front left for around 1 second. If I start off very gently, I can't feel it. The first thing I did was adjust the track. But the problem is still there. I looked at the axle and suspension on the ramp and couldn't find anything there. You can't feel the jolt from the outside either. Noises aren't audible from the outside either. It's loudest as a driver, as it's also transmitted through the steering wheel. I suspect the left engine mount. During the test, the engine tilted slightly, what do you think? Does anyone know the problem? Thanks.
