With alot of cursing and swearing. And a couple of bloody knuckles.
If you can at all find a press, but if you cant like me
Find a socket ( with an extension )the same size as the inner sleave and put the rod over a vice and get a mallet and start hitting. Just be careful that you keep pounding "STRAIGHT DOWN" so you dont get it stuck. Also a little bit of penetrating oil helps, be careful not to splash it in your eyes while your hitting. Dont worry about messing up the old bush, just get it out without messing up the inner surface of the panhard.
Good luck
When you finally get it out check the inner surface of the panhard, if you do have any small scratches or burs either file or crokus cloth them down a "little". Insert the new bush carefully. geting it started (and keeping it)straight is critical. Inserting the bush I used a smaller hammer with kind of like a constant tapping.
Again good luck
