Most important thing I can think of for a noob to know pulling tie-rods and suspension arms,

i. don't take the nut right off, just loosen it so a few threads so the nut is still on the end by at least a few threads.
ii. Put pressure on the joint using the puller, but not don't actually pull the joint apart by winding the puller's nut or bolt: With a little pressure put on the joint, you just tap a strong piece of metal closest to the joint with a 4lb hammer and it will pop out.
iii. Undo the nut and remove.

I broke 2 pullers doing that on my first 5er, until someone showed me.
