Anyone tried to install urathane grease boots on torsion bars?

Boil water, turn the burner off, throw the boots in the hot water for about a minute or so and they slip over easier.

Others say that you can put a lot of grease on them, place a piece of wood under the boot and stand the bar on the end, set on the boot. You then take anothe 2x4 wood and place it on top of the bar, smack the top piece of wood with a 4-5 lb. hammer and the torsion bar slides right in with one good hit.
