Tires rubbing on underneath of trailer

I noticed recently that the tires on the slide out side have been rubbing on the bottom of trailer. It isn't hitting anything but the fabric type weather covering thus far but obviously needs to be corrected. Any ideas on cause and any suggestions on a fix. Thanks for any and all help.

  • Go to etrailer website and look up springs. Click on more information for dimensions. example

    I would bet that your springs are spent.
  • Contact the nearest spring and axle company. They will be more knowledgeable and cheaper than an RV dealer. Apparently weak springs is a common issue.

    Lippert will be able to answer what size/weight springs you could move up to in the meantime.

    OVERLOADED.

    Wrong size tires (did you or previous owner go to LTs?) Check the manufacturer specs and make sure you have to correct tire size.

    Weak or broken springs.

    Bent axle stub (the ends of axles where the bearings/hubs are which also could have happened while overloaded and hitting a curb or pot hole)..

    Just to name a few possibilities.
  • My 22 year old TT rubs once and awhile. I think the springs are just wore out. It sets close to the ground too. I don't go far so I don't worry much. But, new springs would be nice. Keep me posted on how hard they are to change out. I'm afraid all of my shackle bolts are wore and will be tough to remove.
  • Thanks for the quick responses. The trailer has 3500# Lippert axles. Does anyone know if I could just replace all the springs with 4800# springs? What effect would that have? Trailer is not overloaded by manufactor's rating but it has over 35000 miles on it. Weak, tired springs are a definite possibility, I guess.
  • you wanna fix this NOW, if a tire blows it,ll wear up the bottom of your rv in the tune of thousands of dollars.
