The boots on my 84K mile 201 are severed, but the joints are still okay. So I ordered new boot kits from Pelican, and I plan to use Mobil 1 grease when I install them.

It appears that with the front control arms on jackstands, I can lock the brake with a clamp, loosen the two pinch bolts that retain the stud to the knuckle, then use a floor jack to raise the knuckle assembly at the bottom of the rotor enough to gain sufficient clearance to install the boots, and I've made up a tool to spread the retainer ring to slip it over the stud/boot and seat it at the bottom of the boot.
