LCA clearance at frame

How can you tell from that angle?

Here is a better angle.

From your pic, the bushing seems in fine condition

Just an idea, in this image below the center rod inside that bushing seems to sit offset - closer on the chassis side. So if the bushing in your control arm was pressed in rotated 180deg, the center rod would sit too far away from the chassis, which would bring the control arm surface too close to the chassis
May as well look if you got the correct XC70 arm (it has deeper 'channels', like in the picture, it's beefier overall), and not the one for S60 (not sure if it would fit)

The meat around that horizontal bushing looks much beefier than the Lemforder a few posts down, but that picture showing the radius'd side so it could be an optical allusion.

If that's not an issue, I would look into the front shocks and maybe struts overall since they could be allowing too much vertical play.

It also comes to the rubber quality, the quality can vary a lot with the price. Btw, the picture above is not a Lemforder, I think it's a Meyle (not a good quality). Just wanted to show the offset inside the bushing. In the stock Volvo CA the front bushing is made by Boge and looks quite thin but seems to be holding well long time. Detroit Axle may be sourcing the bushings from another part maker, found these reviews on Amazon for a different car https://www.amazon.com/Detroit-Axle-Con ... merReviews

Does the inner CV look a little 'extended' for the car sitting on the ground/wheels turned only part way? Shouldn't it should be closer to the inner limit? I'm wondering if that simply isn't the correct LCA for your vehicle (wider track width). I could be wrong. You'd need to take measurements of the old LCA and compare to the new ones.

The arms were exact is size and dimensions to the stock ones I took off. I am confident they are the correct ones, and I think the cast tolerances were a bit off. I couldn’t really judge the bushings because the old bushings, especially the front, were shot.

Excessive toe-in compressing the bushes causing the LCA to contact the subframe? Note, poor quality rubber that's too stretchy would probably do this under hard braking. Likewise you'd get excessive toe-out under hard acceleration.

Aftermarket non-OEM bush manufacturers often use a one size fits all approach to their rubber 'recipe' across different makes/models. Once in awhile the approach is a crash and burn on certain vehicles that require specific mechanical properties (how the rubber stretches/stiffness etc). That's probably what is going on here. The front-end geometry on these vehicles results in a very unforgiving situation if the rubber on these LCAs isn't 'just so'.

Another 'been there done that' in my repertoire. I tried another brand (not from DA), rubber supposedly 'formulated' just for these cars, but they didn't get it right either. Major issues until I realized what the problem was and took those LCAs off the car.

Loosen the bolts, push/jack up on the LCA at that bushing area and then tighten the bolts. In that picture the LCA front mount looks offset to the bottom.
