Cracked Rear Axle on 5er

Pulled into a fast food place on my way home from Kernville and noticed my rear axle was cracked which made my rear tire protrude out. It was cracked at the u bolt where the leaf springs meet.

Luckily, I noticed it when parked so I pulled the tire off and slowly drove it 1 mile to a possible mechanic. The axle luckily did not come off while driving.

WHAT COULD CAUSE SOMETHING LIKE THAT?

Now that one axle cracked, should I be weary of the other axle. I believe there must be extra force at the u bolt so maybe a leaf spring linkage went out? Lets see what the mechanic says tomorrow. I have to remind him that rv axles have a camber in them.

  • Last summer we had a hub fail while towing. The shop determined that a weld had broken, allowing the axle to move. It was where the Dexter axle is welded to the Forest River mounting bracket.

    Dexter replaced both axles working with our Extra-Ride Extended Warranty.

    Took 31 days to get them in and three hours to get them installed.

    As I looked at the two bad axles, it was obvious the welds were machine made by industrial robots. And that the original axle/ bracket were about 1/8 of an inch off, so it was amazing the welds had held as long as they did.

    That is how something like this happens. Much is done without a human ever really looking at the product to ensure it was done right.
  • I have a 30 foot Jayco 5er. The 5er is 10 years old and I never overload it. What is a reasonable price to replace the axle so I am more informed when I talk to the shop tomorrow?

    Defect or road hazard. Usually they bend and lose alignment.
  • You don't say what kind of RV you have, how old, or how heavy. But I would be taking very good pictures and calling the axle manufacturer first thing Monday morning.
