You can buy a split boot kit [aka sticky boot], its one you can fit without removing the shaft
Some people hate them, and if not fitted cleanly or properly, can fail within a year. But I have used them in the past, with no problems, cleanliness is the key when fitting and its handy if you have [or can borrow] the proper tool for tightening the metal clips
Quinton Hazell sell them from your local motor factors, think they are about a tenner
