Hi all:
A little less than a year ago I bought a 2014 Subaru Legacy. It had around 90,000 miles on it at purchase, and I've put a little over 10,000 on it since. It looked like the car had nearly new tires at sale. During a recent oil change, the technician showed me that the front passenger side tire was down to the threads, but just on the inside of the tire - which is why I hadn't seen it. The other tires were wearing similarly, but not as dramatically.
I had new tires put on today, and then had the wheels aligned to hopefully mitigate that wearing pattern. Naturally, the mechanic came out and said there was further damage and would cost $600+, and he asked about scheduling next week. I wanted more time and a second opinion, so I just took the quote and left. The quote reads, "inspected and found pass rear adjusting link and front lateral arm bent."
I asked a bunch of questions to try and determine the seriousness, safety risk, and importance of repair. Seems like, from what I understand, that the car is perfectly safe to drive - the only risk is the tires wearing way faster than they should, and unevenly. So I'm wondering if I should A) get a second opinion and B) get this repair. On my last car I was told I needed new front struts (to the tune of $2,000+). I drove it for another 1.5 years and 15,000 miles without doing a thing and without feeling unsafe. I also presume that I've driven my current car for 10,000 miles with this current issue.
TL;DR - mechanic noted some issues ("pass rear adjusting link and front lateral arm bent") while doing an alignment. Are they serious enough that I should fix them?
