Totally agree with Wes about the puller versus pickle fork. Used both and there's no comparison. OTOH, all I own is a pickle fork so that is what I do most of my TREs with. TRE puller's on the list along there with a press, plasma cutter...gotta keep prioritizing :-)
Bit of advice: Often one of the most difficult parts of this job are getting the steering arms off the knuckles. Factory (or work-alike) SST would rock for getting that sucker off. I will say that a couple I have done came off (relatively) easy, but once they've been on there for a couple decades they can be some work.
Do the bottom retainers first, for whatever reason they always come off easier, then you can pound a drift up on the underside of the steering arm seat. Like I wrote, sometimes they come off reasonable, other times they can be a bear.
