My focus is a 53 plate with only 55'000 on and the bushes are totally knackered on the back, i think there is going to be a massive improvment once its all back together. Last MOT it was flagged up that i needed to change a bolt on the rear trailing arm as it was rounded which was the start of this nightmare, i thought if i take off the sub i may as well do a propper job and do ALL the bushes. Its a twat of a job. If the nut does not need to be tacked in place then i may leave it i just have a funny feeling that i will never be able to get to the bolt once its on the car so i better get friendly with someone who has a mig welder
