​Had a mishap backing out of the garage and caught the passenger side mirror on my 2026 Limited.

I am trying to figure out if this is a fix or a "replace the whole assembly" headache.

​The Damage:

​Blinker: The clear glass/lens for the integrated turn signal is cracked.

​Structural: The mirror housing has a wobble over bumps. Crucially, the three mounting bolts to the door are tight. However, I can physically lift the mirror housing up away from the bases slighly, which tells me something internally snapped or broke.

​What’s still working:

​Electronics: Power-folding, glass adjustment, and heating all work perfectly.

​Sensors: Blind Spot Monitoring and Rear Cross-Traffic Alert are still reading correctly with no dashboard errors.

​Aesthetics: The painted "skull cap" and the actual mirror glass are undamaged.

​Questions:

​On the 2026 Limited trim, can I buy just the internal "skeleton" or sub-assembly and swap my electronics/covers over?

​Has anyone replaced just the turn signal lens on this generation? Is it accessible by just popping the outer cover?

​Given the tech in the Limited (sensors/cameras), is there a calibration risk if I DIY the sub-assembly?

​I would prefer not to buy a whole $700+ assembly if I can just swap the internal frame and the blinker lens. Any advice or part numbers would be appreciated!
