No instructions like the Moog joint that has you seat the boot. Moog says to use a channel lock or socket to drive the boot down. There is about a 3/16” gap between the bottom of the boot and the top of the control arm. Take a look at the photo, I think I should do something similar to Moogs instructions.
There's a metal ring in that bottom boss of the boot. You can pull it down with the channel locks or remove the spindle again and drive it on with a socket. Exhaust pipe is too thin and will cut the rubber on top of the ring. Use a rag, doubled over for the channel look too. It does need to go all the way down to seal.
