Rear suspension bushes
 

While trying to change rear shock mount, the bolt for the lower arm to HuB snapped.
I have a replacement bolt but the old one is seized in the bush !!!
Anyone know where I can get a replacement bush before I cut out the old bush?

Any online OEM parts dealer.
But year and model will be needed ;)

Welcome to the forum

It's really difficult to suggest how to remove it without and to reuse or not damage the control arm without at least a clear picture of the broken bolt and surrounding chassis parts. . The part diagram is fine but does not show the real area.

I would try to drill out the snapped bolt.

Is it threaded
 

If the arm isn't threaded ,use a punch and drive it out. Then lube up a new bolt and drive it in and install a new nut . .

Did I miss understand what the OP was asking?
From my reading he was asking about where to get a replacement bushing not how to replace it.

Ya it is not real clear I suppose can be taken a couple different ways bolt or bushing or both? And forget to post the year of the Mazda?
I may have read it the same way because the bushings are easy to find so I would have answered the removal of the bolt like the others did: That is also why I asked for a picture and not a diagram of the area being worked on.
