When I measure the run-out in my axle(hubs off, motor running in first gear), one side is perfect, the other side has about 1/16" of wobble. Should you get these fixed right away, or wait until you really bend it? Also, is there a stronger axle out there? I wasn't getting too wild, just landed on 1 back tire.

 

You can send it back to Lonestar and have it straightened under warranty if you registered it when bought. RPM makes a good axle but I don't think it is any stronger, they just have a better warranty.
