Next step. I am learning that all is not what is was or seems to be.
Working on the Knuckle unit now and was set to install new " PIN " bushing in the lower end.
The OLD one looks threaded and screwed out and smooth back in.
The NEW one is similar to the inner upper / lower control arm bushings, as it appears to cuts its way in.
I hesitate to just jam the new bushing into the threaded knuckle before consulting with you here.
Advice please from all.
Many thanks again.
