Front end shakes/wobbles, feels like tire is going to come off

I recently started having a lot of issues with the steering and suspension components of my car. The first repair that was done (and definitely needed) were the rear wheel bearings. Long story short, the mechanic did not do it right and I ended up needing to get them replaced again right after.
After the second bearing replacement, the noise was gone, but I was still experiencing the same steering wheel issues (excessive side to side play and wobbling at low speeds or going over bumps). I had a certified mechanic do a full inspection and the diagnosis was worn tie rods (driver side inner, passenger side outer). I ordered parts and had both outer and inner tie rods replaced which caused severe misalignment in the front end (which I know an alignment is necessary after tire rod replacement) so I had the front end aligned.
After that, most of the problems went away, however, I am still experiencing a few steering and/or suspension problems.
The car now pulls slowly to the left which I am wondering might be a result of uneven tire tread? Drivers side has significantly more tread than passengers side. I have also been noticing a wobble in the front end that feels like the tire is going to come off, especially at lower speeds. I checked the lug nuts and none feel loose.
I also hear a slight scraping or grinding noise at all speeds but it does not sound like a bearing noise.
Also, the steering wheel is starting to develop side to side play the more I drive it.
I just put a lot of money into repairs so it will be a little while before I can get anything else done, but I wanted to see what some of the possible causes could be or if it sounds like something could have been damaged in the process of getting the other repairs done.
The vehicle is a smaller size SUV V6, automatic, with independent suspension, front disc and rear drum brakes if any of that information helps.
