hi guys had an advisory on my mot today on the rear lower arm suspension bushes having play in them, it was described as a cotton reel type bush. i'm guessing he means the ones in the hub? in which case it'll be worth me replacing both i guess is it worth changing the concentric bolt for the camber adjustment at the same time?

If you search my posts I did a bit of a write up but I changed all my nuts and eccentric bolts and my inner track control arm bolts had seized into the bush so couldn't be removed without cutting the heads off.
There is some odd little washers as well if I remember correctly which I also changed.
I like to grease up the bolts when fitting them to nice new bushes
