Mk4 Fiesta Rear Suspension Bushes Help

[lisajo]

Hi,

My fiesta failed its MOT on amongst other things a rear susupsenion bush/pin having excessive play, I understand this means the bush needs replacing.

My question is, is it better to replace the bushes on both sides? im a bit concerned that just changing the side thats failed will cause the car to not be equally balanced?

Thanks if you can help
