Hi, I'm new here but, need some help diagnosing an issue I'm having. I have a 5-speed manual and months ago I started noticing that when shifting hard or downshifting I'd get some clunking under the hood. Now, my first thought was "oh no, it's either transmission or motor mount!" Brought it to aamco to have them put it on the lift and check it all out. They said absolutely nothings wrong with it. They said I probably "wasn't shifting right" I've been driving for 15 years and learned how to drive in a ____ty 89' Corolla 5 spd manual that 2nd had gone out in. So I pride myself in being able to drive anything and I've actually only owned clutches besides one automatic bmw X3 only because they didn't have a manual option. I know how to drive a clutch. Anyways, now it's to the point that the driver's side what seams to be wheel is violently shaking and humming especially when I get up to 50-75 on the highway. It will completely stop if I turn the wheel slightly left but if I turn it even a little right it gets much louder. At low speeds like turning into the gas station or down a street it doesn't click or pop. So, I haven't suspected a cv joint. I was thinking wheel bearing. Jacked it up and tried to wobble side to side and up and down and it's perfectly tight both ways. Got new tires since I noticed that particular tire was worn uneven on the tread. Didn't help. I do know the previous owner did some upgrades to the suspension, got drilled/slotted rotors, sway bars, cold air intake, carbon fiber hood, and after market rims. If that helps. What else could it be? I'm very stressed about this and need to fix it ASAP. Any ideas would be greatly appreciated!
