Replacing the subframe bushings

Hello! I’d like to know if replacing them is possible by hand with a threaded rod and adapters (and a brute force). I can buy a 3/4" acme threaded steel rod with nuts. They seem to have pretty strong threads. Or I need to find a shop with a side hydraulic press?
Thank you.


What are the subframe bushings?

Front subframe rear bushing. The subframe holds the engine and the front suspension. You’ll find pictures if you google XJ40 or xj6 front subframe.
