2014~2021 Suspension part replacement

[Bolini]

Have a 2015 6 115k miles with clunking noises in front & back. Plan on replacing control arms & stabalizer link in the front. What usually wears in the back on these? Trailing arm, upper, lower, lateral & link?

I also have a 2015 Mazda 6.

Have you actually diagnosed where the clunking is coming from?

Control arm ball joints and stabilizer links are good starting points, but it could also be tie rods, strut mounts (though i never had issues with my mounts) or sway bar bushings.

Regarding the rear suspension, check your shock mounts.
