Here's a tip to make the work easier and quicker...
Don't seperate the ball joint like the manual recomends, instead disconnect the sway bar end link and the front lower control arm mount. That will give you enough play to replace the axle without messing with the ball joint. If your good it should only take about 30 to 45 mins per side
