You don't need one on most Honda's...just use an impact and back the nut off. Sometimes lay it down and step on the spring and other times just leave it upright and push down with your hand as you back the nut off. Done it dozens of times and never once had an issue.
Accords and their double triple wishbone reverse multi-link scissor action bs rear suspension can be a pain sometimes though.
well, if you're putting stock suspension back on...a compressor would be necessary.
