Front end creaking at low speed, Tie rod ends perhaps? Options

[S8S8]

Since the conversion I've picked up a strange creaking noise from the front end. It happens mainly at low speed, particularly when coming to a slow stop at the traffic lights.

I first noticed it when I had the exhaust fitted up. I thought it might have been something to do with the exhaust rubbing, but I took it back for the guy to have a look at and he reckons it's from dry tie rod ends. He claims that I probably couldn't hear it before because the engine was so loud (no exhaust at all!). He seems like a legit guy, so I don't think he's bullsh!tting me.

Has anyone else experienced this noise? I've done a few searches of the forums and see that tie rod ends do come up as a similar issue. I've gone through and checked all bolts and fittings and can't find anything loose that could be causing the noise.

Any other ideas?

Thanks
