My car has been clunking at low speeds over rough roads lately, and I think I've pinned it down to the drop link on the nearside as there is a bit of play in it.

Is it wise to replace both sides at the same time or can I be a cheapskate and just replace the nearside?

I managed to get away with changing one side

It's wise to replace both sides. Especially if more than likely you'll end up with a part slightly different to the other side.

If you want an upgrade... Then you could get 2 meyle HD ones for £40...

*shrug*

Just changed the one in the end. Hooray, knocking noise gone
