My WRX STI 2010 hatch has recently failed the MOT due to creaking from the front. Which he expects it to be the bushes. So just trying to figure out what size/make I need or is the best.
My anti roll bar measures 22.5mm so I would have thought 23mm.
But 21mm seems to be the standard size for my model. So I'm guessing it's had an aftermarket anti roll bar put on?
What do you think/ recommend?
See pics below
Cheers, Tom

I wouldn't measure the diameter there- it's near where the bar has been bent and the diameter and profile of the tube is likely to be different near the bend. You're best off measuring in a straight section in the middle if possible, making sure the area is free from corrosion with an emery cloth or similar if required. Might even be best removing a bush and measuring the diameter there?
Having said that, I'm not familiar with the std. finish on a hatch ARB but it looks like there's the remnants of silver powdercoat on it which might suggest an aftermarket bar? Someone else on here may be better placed to advise. Looks like it might have multiple places to bolt droplinks into on the left of first picture? That may also suggest an aftermarket item.
Just take the bushes off and grease them up. They creak because the have gone dry
This! It's why I went hardrace rubber in the end. It's the work of a few minutes to unbolt them and re-grease with something sticky and thick - marine sealing grease is what you want.
Looks like Whiteline. To complicate matters, Superpro advertise that as their paint finish is so thick that the bushes are half a mm bigger to accommodate the bar.
I'm surprised that creaking is a fail, without noting wear of any kind. Just grease it, as above.

The new bushes should be here tomorrow anyway
I have some of this, surely it will do the job?
The yellow poly bushes on my whiteline rear ARB squeak like mad, it's another one of those jobs I need to do, as said above, I'm surprised it's a fail if they're not actually worn.

Fitted them today and it has got rid of all the creaking....
But when I took it back in he said just it wasn't the anti roll bar bushes that it failed on. It was actually the wishbone pins/bushes.
If it's the pin bushes I'd have thought it was 36B on this drawing rather than the front bush that you have above.
36b will be the one. Because it is vertical on the hatch and legacy, it wears much faster than the new age horizontal ones. It was changed to a pillowball type on my11 hatches. I would personally use Superpro or Powerflex rather than Whiteline.
If it's worn, a new one will transform your handling, together with 4 wheel alignment.

So it must be these ones?.... I will get the right ones eventually 😅

I'd probably call that a bit thin. Fine for bearings etc. Proper marine grease is borderline glue, it really is that sticky. Amazing stuff for waterproofing!
OK, I know next to nothing about your MOT inspection process, but here in New York state the inspector must write down what has failed on an official rejection form. Do you have anything like that? Because from what I'm hearing it sounds either like the mechanic is 'fishing for business', or else the OP just didn't hear (or want to hear) what the real problem was. Just "creaking" without any play in the suspension sounds like a job for a can of silicon spray lubricant to me. I've never heard of a car failing an inspection just for being squeaky.
Yeah, the car should be provided with a fail sheet.
In that case, it should be obvious what needs to be replaced, yet the OP is first replacing sway bar bushings, then later pivot bushings. Something here does not add up.

The OP confirmed he was wrong about the sway links, his documents confirmed the wishbone bush was failing.
Now, I assume that they were rejected because of play, rather than just squeaking, If a squeaking suspension is enough to fail your car, then there are a lot of illegal cars on the road right now!

It was due to them being 'shredded' but they do look cracked to be fair
