Trailing arm bushes are common to go in the rear on EK's.

Mine need replacing, sounds like a donkey at the moment when I go over speed bumps, also it makes a single clunk noise when you start driving after about 5 metres. I originally thought it was my dampers and handbrake or something, but I got the Honda service centre to check it out and they said it was a common thing.

I'm gonna go for the poly ones from Fulcrum, I'll let you know what the ride is like when it's done.
