it's not hard at all,i just took the whole spindle out. and pressed on the lower A arm with my foot and it slid right in. just make sure when you put the spacer on top of the coil not to take off the factory rubber pad on top of the coil. and when you get the coil in your gonna need to put a jack underneath the lower A arm so you can jack it up so bolt it back to everthing
i already had the 1.5" daystar before i added spindles. i put the spindles in and a 2" block and it was nose high and i added the 3" block and now it sits perfectly level
tractor supply they came with the pins but you will need to dremel the hole in the frame a tad bigger. just make sure you dont leave it bare metal.
