The problem with removing the boots to 'upgrade' the grease is the clamps. The surfaces need to be completely clear of any grease or they will slide off in use.You won't notice and .. a big mess.
The best clamps are Oetiker but they need a special tool to tighten correctly.

There ar alternative clamps. Pelican sell the clamps and tool. I bought a special tool that is tighted with a ratchet because of access issues with the axle fitted to the car.On the bench it is easy.
