how easy are they to change as ive never done them, is it worth getting powerflex ones, im pretty sure this is where my creaking coming from v annoying, the anti roll bar was abit rusty by the bushes, give it a spray up and now it has got worse lol, really annoyed as going to york on friday so aint got time to get it booked in at skoda , as its still under warranty and the suspension is bout the only thing i havent touched yet lol, also is it 19mm the roll bar on octy rs mk1,

I'd defo get it done under warrenty, as they sometimes have to replace the ARB as well as the bushes.
