took me 40 minutes by myself, a set of stands, and 2 OEM jacks to lift up the car, replace, and lower the car. Really simple. Just make sure you dont over tighten, and you screw the bolts in by hand first.
When I do them here at the shop. I don't even use our lift because it takes longer to get it lifted then to just use a jack and crawl under the car and do it.
Like people have said you can have it done in 30ish mins.
