Why is it that the inner boots are more problematic than the outers? It seems like more and more people are saying to watch out for the inner boots and make sure the fins aren't touching. But the inner boots have a more "rolled" shape, not the bellows shape that the outer boots have. Looking at my axles, the outer boots look more prone to wear than the inner ones.

What gives?

the inners rub at the same angle (side to side) all the time but the outers change with turns. The outers are also better designed for flexing than are the inners. The OE boots were never meant for the steep angles we put on them ;)

Downey and CV Unlimited sell hi-angle boots, around $50/axle for the complete kits. But...even they will wear out with too much lift.

The inners run at the same angle, or did you really mean "rub"? I don't really see how the inners could rub, because their fins are so spread apart. About the outer ones flexing in the turn, to me that means they should wear faster. The inners are only maxed out when the suspension tops out.

I guess I'll just have to wait and see which ones spill their guts first, lol.
