There's a difference in doing the anti-roll bar bushes (as Buckster has done) and doing the suspension arm bushes. The arms can be difficult to remove - sometimes the only way is to cut them off and then you need a new arm. One could change the bushes on the new arm for different ones, I suppose, but it's an added cost. Some fit aftermarket arms with improved bushes already fitted. Example of some of these here:

2008 TDV8 - it was a labour of love and is much missed

Hi
I'm also having the ARB - anti-roll-bar bushed replaced - just I'm getting it done
as I'm not that confident on the actual work

But yes, when the suspension arms need doing then deffo will get replacements with the bushes already in. Current car - 2016 MY17 L494 in black - sometimes towing a Buccaneer Cruiser.
