I like to run a hot bath leave them in for 20 mins, get a helper... Tap with dead blow hammer or a regular hammer and block of wood... any bit of lube on the aluminum skid helps even veggie oil or dish soap works.
Make sure they are going on straight, when they are good and warm it's easy to wreck them by tapping them off course which chews through the side of them... Take ur time and don't be afraid to give it a good wack.... Some of the aftermarket hyfax aren't exactly perfect, so it will likely require a bit of swearing!
I am praying for sno for us man! and I don't pray, lol
