Cast-o-line

I have a std 80 series and after a trip last year to central aust, it suffered quite bad wear on the outer side of the left front tyre. Prior to the trip the vehicle had a new set of ARB springs installed which gave the vehicle about a 40mm lift. Before this, this type of tyre wear was present, but not to this extent. The caster and camber have been measured as:

Caster: Left +3/4, Right +3/4
Camber: Left +1/4, Right +3/8
Toe in 0.5mm.

I have been told that the eccentric bearing of the cast-o-line can correct this problem. Has anybody used this product and is there anything I should be aware of?

Thanks
