Upper control arm bushings
Is there an easy way to remove the rubber bushing from the upper A arm without damaging them? I have not yet tried to use a press but before I did I thought I would ask,
Thanks.
Thanks.

Why would you want to remove them and not damage them? You might just as well replace them with some new ones...
When they're good and you want to paint the A-arms, just cover the bushings with some masking tape (or don't ;-) )

Short answer- No theres not even a hard way.
The problem being that pressing out the first bush requires that you do it using the upper A arm mounting bracket thingy (I'm always stumped what to call it - the thing the bushes pivot on) and because of it's design it just pushes the rubber out of the outer steel casing of the bushing which remains in the A arm.
It would I think be possible to fabricate something to prevent this happening but I reckon it would cost a lot more than just buying a new A Arm with new bushings.

In that case it's easy - Support one end of the A arm and press out the centre of the bush in that end using the mounting bracket. Turn over the A arm and repeat for the other bush using using 38-40mm OD mandrel. Then hacksaw carefully through about half of the outer steel casing of each bush and use a thin cold chisel to split the outer case from an O into a C. Push out with fingers.
Putting new bushes in is more difficult.

Thanks. It does look like it is easier to do with a press. I will give it a try. I am simply trying to get the center part out so I can plate it.

If you don't have access to a press you can use a properly sized drill to drill out the rubber material between the pivot pin and the outside of the bushing. This will free it up enough to allow you to get the pivot out. Then you just have to remove the remaining portion of the bushing per the hacksaw method Jon mentioned.
