Thanks Turbs. I understand what you're saying. I possibly have at least as good an understanding of weight and load limits as most folks since I've been dealing with axle issues on 3 different trailers beginning in 2008. I believe that, in an attempt to keep trailer weight down, some manufacturers install axles that are only marginally adequate. I've had 3 bearing failures, one axle destroyed, and spindles grossly out of alignment even though I have never loaded even close to GVWR, and have always been faithful at annual bearing maintenance. I've had one axle replaced under warranty on one trailer, both axles replaced on another trailer (cost shared by manufacturer), and recently on a third trailer, axles realigned. That process on a torsion system involves bending the axle tubes until spindles are in alignment. I'm deeply concerned about what that might have done to the integrity of the axles and mounts. I don't want to install heavier axles so I can haul more stuff; I never have hauled much. I just want to get past 7 years of wondering how far until the next major failure. We tow about 8000 to 10,000 miles each year, and expect some problems, but this has been almost more than I can tolerate.
