I'm having an issue with my tent trailer "eating" tires. the shop said that I should just need to replace the axle (a "torflex" rubber torsion axle) as there is no allowance for adjustment and the axle is probably bent. I'm ready and able to replace the axle, but, before I lay down a few hundred dollars for a new axle, is ther a ready way a shadetree mech like me can check to make sure the axle is simply bent and not some other damage to the frame or other that is causing the alignment to be off.

(Does that make sense?)
