If you have all the tools you need to do it and a decent idea of how it's supposed to be done then it should take you and someone else with the same knowledge about it as you... about 7-10 hours (give or take about 2 hours). My brother and I got mine done in about 10 I think, and we had almost everything we needed (we had to borrow some things like a torque gun to make things move faster) and we only messed up once. So, it's not a lot of work but it does take a decent amount of time even if you know what you're doing and have what you need.
