General Suspension Question for not a Tundra

So I'm at "that point" with my wife's car. Its a 2012 Flex with 160k miles and has been problem free minus a $300 part that went haywire years ago. Just been routine maintenance otherwise. Just put new tires on it (~$1100) and went for the 4 wheel alignment like a good soldier adhering to the warranty requirements on said tires.

The garage had it for ~4 hours for the alignment and couldn't get it back in spec. Left camber is out -2 and right is out +1.3. I have no idea what that means other than eventually I'll have uneven wear on the tires. But it drives straight, so partial win? I was told I needed new struts. Ok. Quoted me for $684 out the door and I told them I'll think on it and get a second opinion.

Went to the other garage I use (that replaced these very struts in 2021 at 131k miles) and was given the list... New struts, new control arms, new sway bar linker, and rear shocks and a rotation... all for ~$2400. They said this would be "doing the job right." Do a KBB or edmunds guess and this is half the value of that car.

Its been a solid car thats been paid off for years and my wife still loves it. I don't mind putting money into, but at the same time I don't want to be sold some BS from a garage. Is this something that should be taken care of? Or just let it eat tires until the car quits?

 

My question is since the struts were replaced just 3 years ago, why do you need new ones?

 

From my "minivan offroading adventures". No, kidding. The garage only replaced the struts, but not the coils/spings/etc. Why they need to be done again is beyond me. Its been a frustrating experience. If I let it eat the tires and replace those in 4 years the car will have ~200k miles and financially I'm still ahead even paying another 1k for tires.
