i braced an aluminium axle i had on my vit and it made it last a bit longer ... the only other problem with aluminium axles is the 3 bolt hanger bracket also sometimes gets ripped out, destroying the casing when it snaps .. i had this a few times... save the messing around and get a v6 steel front end .. its the only fix in the end... or copy the rear axle conversion to make an ifs front unit like mike hagen runs . its a lot of work but in the end unless you are using a steel axle you are wasting your time if you push your truck hard ... i broke 9 front axles before i fitted the steel unit and lsd's
