Bob thanks for your reply.

I wanted to ask you; did you do the job by yourself?
Do I have to take the springs out? My neighbor has a spring compressor tool, I think.
I suspect such a job is a big undertaking. I replaced the UCAs, but that was relatively simple, I think.
If you did the work on your own, could you please advice with steps that I have to follow?

Thank you again,
John
