Well definitely don't take my word for this, but if you're feeling confident it could likely be done in an afternoon. Maybe 4-5 hours. Passengers side only took like 20 minutes, although the first time took a bit longer. For the tension arm- yes torqued with loaded suspension, OE Lemforder. Could have gone this route again as I did purchase through FCP and had already claimed the warranty for the replacement set. Really I would love to try one of those monoball setups but $600 is a little steep so the PF seemed like a good middle.
