question on leveling kits and cv leaks?

[resparza0311]

just put in Revtek's leveling kit for my 2002 tundra, kit raised front end 2.5 and rear 1.5, question is... been reading a bit about CV boots leaking due to leveling kits and that a differential drop kit fixes the issue... kinda a newbie when it comes to technical stuff but refuse to have anyone but me work on my truck, do everything myself no matter what... so kinda get the problem of not knowing alot of the problems which will come out of this, anyone got some insight for me? what does the diff drop kit do and will i have problems with my cv boots with the before mentioned leveling kit. thanks in advance!

The boots leak because the internal volume changes, and the stock clamps aren't very tight.

There are two options, you can pick up a clamp tool for 10$ and tighten the stock clamps before you install the kit, or you can use hose clamps and do the same thing. End result is the same.

Diff drops decrease that effect but not by much.
