Hi.... 👋

Replacements are sold by MX-5 Parts as Rear Hub Upper & Lower Lateral Arm Bushes, MX5 Mk4 & RF 2015> ...
Polybush Rear Hub Upper & Lower Lateral Arm Bushes, MX5 Mk4 & RF 2015> | eBay

It's a common problem on the ND that Mazda are aware of, and will make a contribution to the (expensive) repair as long as the car in question has a full service history with Mazda...
However the replacements are 'like-for-like' and not a lasting solution and will soon need replacing again...

Hope this helps?

Hate to be the bearer of bad news, but there are no over the counter tools to fix this.

A member on the fb pages is selling them for 100-150 notes, but someone has done it with a corsa/vectra/omega bush removal tool here but unable to gain more information from that user.

I'm trying to figure out what one it is as if it saves a lot of people a lot of money, it can't be a bad thing.

I've had cars with these bushes before and when I replaced them with poly bushes I had zero issues after, regardless of what anyone says.

Plus Roddison is running them on his track cars, so can't be all bad.

From an engineering perspective ( I haven't looked at the job in detail)....I'd think that the hub would have to be stripped from the car? ( great if you didn't have to but would then as you say require pullers/drifts to remove/replace bushings).
I'd think removing the old bush the more difficult process, but judicious cutting and use of a chisel probably the way ( I've done this on various bushes in the past on a multitude of vehicles).
Drawing in the new bush no more difficult than a length of screwed bar and a strong flat plate to pull it in....These are methods I've used previously.
I don't know if I'm wide of the mark with my assumptions, but don't know anyone that's done this as a D.I.Y job.....
And the bushes on my ND seem okay at the moment! 🤔

I did the tops by removing the hub and then using a press and a 31mm socket to press the old bush out. 31mm being the key here as it will give enough purchase and also not hit the hub itself. The bottom ones are more problematic using a press, but someone has used a Vectra tool to get it to work, what one I have no idea. but I'm not far off finding out what one it is.

Thank you ....Interesting to note should the need arise!....Did you use the new bush kit from Mx-5 parts?
