It just looks like the grease pushed the lip of the rubber out. Can you gently just push it back in?
No. Small screwdriver and some patience. Of course you will have to pop the tie rod end out of the knuckle to get the boot on. No biggie. Pull the cotter pin, wack the casting near the tie rod end with a hammer (preferably a brass one and pull the stem out of the taper.
just wondering what size Tie Rod puller work on the L3301?
