Does anyone happen to know the thread/size of the lower control arm bolt nut? Day dreaming about a non-destructive removal method and need to cost out a tap…

 

Gave up googling too fast…. Appears to be 9/16 UNF

 

Front or rear suspension?

 

Front!

planning to make a sacrificial extension and a correct angle pipe thing to press the lower fulcrum out.

 

I had to use a sawzall with a metal cutting blade, which wwill just go between the cage and the wishbone eye, to cut my fulcrum pin each side of the cage, and thus release the wishbone. Then burn the old bush out of the wishbone eyes, and then I could bash out the pin, eventually, from the cage. I hope you do not have to go to these lengths!
Use loads of nickel anti-seize on the new pin where it gos through the cage.
