Shock Absorber Question/Steering Issue

[JWRS4]

Is it safe to replace a shock absorber on 1 side only on these clios? I have had the o/s/f absorber changed under warranty but the n/s/f is the original on around 30k miles ?

My steering wheel is no longer on centre and drives in a straight line with the steering wheel at a slight angle to the right although I am not 100% sure if it was like this before or not, I have had the car aligned all 4 in the green so not sure what is causing this steering issue

Edit: its a 200 edc 2014

Always best to replace in pairs. Whenever you replace any suspension component it's best to get it stuck on the tracking gauges
