Of course, if the boot is compromised and there is water, salt, dirt inside,
the joint should be
cleaned and repacked. You might be able to get it clean enough using a
solvent wash without
opening the joint, but getting new grease into the inner bearings might be a
problem.

Some people actually identify and replace deteriorating boots before they go
completely to hell.

The first boot I replaced, I inadvertantly allowed the joint to
separate(even after being warned and
taking considerable care) , and needle bearings and balls went everywhere.
I finally managed to find
them all, clean everything meticulously, and packed everything back into
place. This was a real
learning experience which I do not care to repeat.
