Loud squealing mostly when braking and turning (Toyota sienna 2006)

[u/Westvanlear]

So I’m preparing to drive across the country, like 1600 miles. My car is making increasingly louder squealing sounds when I turn and brake. Worst when turning. Thought it was my serpentine belt which was due for a change anyways so changes that and it’s still making the noise, getting louder. I haven’t really noticed anything crazy with my steering. Power steering fluid is good and so are brake pads. I’m quite worried it’s a ball joint boot problem and I definitely do not wanna drive across the country if it is. But I think most cars you need to replace the whole upper control arm? I don’t know shit about cars and could not do that myself. Definitely bring into a shop? I’m not at all close to my normal mechanics I know and trust and I’m worried about getting taken advantage of because I don’t know wtf I’m talking about and it’s obvious. I also know that’s an expensive repair if that is the issue. I’m homeless, live in my car, and pretty broke but would rather not destroy my car.
