Rear inside tire wear. Bent axel?

Hi
I have a 4 year old 30' bullet. I noticed that the inside of both rear tires are completely worn out - a bit on the outsides too but not nearly as bad. The fronts are wearing fine fand only maybe 1/3 gone. I read this can be from a bent axel. I do see a wow in the axle but have also been told that some bend is normal. True?? I don't remember doing anything that would have bent an axle. Replace the axle?

Am I good to replace the tears with new ones or do the fronts need to match?

Thanks for the time.
  • Ouch. Glad to hear it was covered. I didn't notice anything like that but I'll have to have a better look at mine. If nothing is so obvious what else can I look for to know if the axle needs replacing? Am still wondering if the slight arc is normal.
  • Here is what happened to my axle after many very very large chuckholes on I40 between California and Flagstaff Arizona about 8 years ago.

    Notice the axle tube has collapsed.

    Lippert did replace the axle under warranty.

  • Thanks. Strange with the upward arc. I see this on the rear axle that is wearing but not the front which isn't wearing. Is the arc supposed to be only on the rear?
  • There should be an upward arc in the axle. If it weakened and is straight ,you will wear the inside of the tires. Mine did that and had both axles replaced with 4400# vs old 3500#.
  • Just running up and over a 4" curb in a parking lot can bend an axle. I had inside wear on my dual axle Jayco, and even though I had not exceeded my GAWR, one of the posts here recomended getting heavier 5000# axles rather than keeping the original 3500# axles, which I did, and sure enough, inside wear went away. Checking alignment is also a good idea.
