    This happened after I was changing the brake pads on my front rotors and the jack buckled because of uneven sand underneath as shown in this picture.

    Ever since then my steering wheel feels very loose, car sways at high speeds, steering wheel jitters above 80mph, and the car micro-steers on its own which requires constant adjustment by steering wheel.

    I've had busted sway bars before and this is not it, I already checked and replaced the sway bars to be sure. With busted sway bars the steering feels sensitive at high speeds and will sway in windy conditions. But doesn't micro-steer randomly from left to right without moving steering wheel. What part is likely damaged?

    So so now all you have to do is you've got the car back on the road put it in blacktop or concrete Jack the car up again and on this side take a long pry bar and wedge it in between things and bounce the pry bar gently and see if you see any slop anywhere got to be something The sand shouldn't have really heard it even if it rolled off the jack I've done that with one of my generation threes not paying attention didn't hurt a thing No looseness no alignment needed nothing I was changing the hubs which is a little more involved than changing the brake pads I'm assuming you are sure that the wheel is on tight and so on.? You can't have any looseness falling off the jack with the wheels aimed straight ahead usually results in the jack getting a little bent especially if it's the jack that came with the car I don't know what you would have been jacking the car up with in that sand You would have need your mini floor jack slid on a 2x4 better. But anyway that's where you are or you can just drive it to a alignment place like Mavis tire or something they'll tell you real quick what's wrong with it this is generally very simple and quit diagnosis.

    You need to safely work under your car, using a scissor jack on sand is very dangerous.

    There may be multiple issues with your car. From alignment, wheel balance, bad bushings, bad struts, end links, etc. You really need to thoroughly look at the suspension bits and make sure nothing is loose or damaged.

    ^ This.

    I know, hindsight. We’ve got a smallish square of 3/4” plywood in the hatch tray, maybe 10” square. And wheel chocks.

    Ain't no way I'm going underneath my car with just a scissorjack. Changing a brake pad doesn't require you to go under.
