Cv Joint Or Engine Mount?

I've got myself on abit of a mission to close of those little annoyances with the car Ford Fiesta 1.25 Petrol 2009 plate (60k miles)



I currently have taken the time to replace the bottom engine mount at a
total cost of £10 and 2 new droplinks in a hope it would stop a knock
happening. I also had some custom work on the exhaust to fix the issue caused by the engine mount.



However I still have a knock when turning to the right, be it what feels
like smooth tarmac or rough - this happen both in and out of gear.
However also to accompany this, when going to pull away there is
sometimes a single knock.



I've been advised to look at the CV joints (this seems simple enough to do by jacking up and inspecting)



Based on the damage to the exhaust from the lower engine mount should I
get the top engine mounts checked? Is this easy enough to check myself? only issue with this is I am unable
to source the parts apart from Ford direct. I havent asked for a price
on them yet!
