Think I've got a bent rear axle tube, this is on a dump truck so for a background to the issue, chronic overloading is a daily occurrence.
Getting some pretty gnarly tire wear on my inner dual on one side of the rear axle on my tandem. Inflation issues as a culprit are ruled out, I have cat's eyes equalizers, keep up on them and check them to make sure they have not failed.
This leads me to believe I've got a tweaked banjo housing (drive axle tube, not a house for my banjo), is there a way that I can measure this myself with basic shop tools, or is figuring this out a job for a shop equipped to do 3 axle alignments?
Also aside from down time, anyone who'se had this problem would you be able to give me the long and short of repairing / cutting and re-welding vs replacing with a new or possibly used axle?

If it is bent bad enough to eat tires badly you can probably see it but put a level on the side of the tires top to bottom. Then jack it up check the bearings, rotate it a half turn let it down and check it again. Also check the others so you know what you are looking for. Use a tire square to check duel mating, they should be with in 1/4 inch and the smaller diameter tire normally gets scrubbed off. Scribe the outside tires and measure between the lines as close as possible from top and bottom, front an rear. Make a gauge with a 2x4 and two pieces of 1/4 all thread rod, ground to a point, if you have to. If it's bent buy a used one.

You will have to remove axles and ck, all bearing free/play and have someone with a end play gauge set all of your bearings inside hubs before you start replacing the tubes, if you find more than 4 to 5 thou. of wobble free/play you found the tire eating problem, it takes some time to adj. them back down to your axel spec. by tighten the out side nut to spec. then ck. end play again you should look up inside spec sheet but most are set to 1 thru 5thou. end play

The best way is to pull tires and axles, check that your wheel bearings are good and snug them up for no end-play. The use a precision level on the axle mount surfaces of the hubs, they should be parallel. Only works with a good level or angle gauge that will measure fractions of a degree though. When you're done, you'll have to reset the end-play to specs.
Do you have any issues with axle gaskets blowing out? Loose bearings and bent axles often chaff the gaskets out.baha Thanks this. -
I had one inside tire wearing on the inside but I was also getting choppy wear on my steers. was a misaligned rear axle. 3 axle alignment fixed it good.
call alignment shops and ask if they can bend axles to adjust camber or if they are only able to shim it?
if they can't bend it then they aren't a proper alignment shop, go to the right guys fir this one.
