Control arm pairs

Hey there, M3'ers. Need some advice.

(It is actually for my wife's 328i 2011).

The right front control arm (forward thrust arm) has a worn out bushing. Am planning to replace the control arm this weekend.

My question:
Do I have to replace the left control arm, too? There is conflicting advice on replacing individual arms versus both. In other words, do both sides have to be replaced at the same time?

I think your wife will likely not be able to feel the difference between the two sides. I have unilaterally changed suspension bits on my daily driver cars without any hiccups. An argument for changing both is that if you are diy'ing it you will have all the proper tools out, and in the mindset to do the job

its not a question of whether or not she will notice, it is an issue of putting a worn bushing with a new (firmer) bushing. your alignment may suffer.

Replace both. Make sure you torque the 18mm (tool size) bolt down with the suspension loaded at ride height. Otherwise you'll destroy the new bushing when you lower the car off the jack.
