The R&R is 90% of the job, the real PITA.

No, don't pull the rack for just a torn boot!  The high pressure rod seal
will start to leak soon enough, then replace both.  The ZF boots are good
but some of the aftermarket boots have a very short life. BTDT also, my 5K
rack went for 100K with torn boot.  Nothing behind the boot that a little
water and dirt will harm anyway.  DFI if IAB!

It would require removing the external hydraulic tubing to slop the new boot
over the cylinder, as I recall.  No internal disassembly.  Certainly not
worth the effort just for the boot.

Another reason for DIY.
