Replacing Your RV Suspension is Easy

Enjoy this DIY video on how to upgrade the suspension on a 2017 Keystone Outback 240URS. I've driven this towable RV for roughly 35,000 miles. We bought it new in 2018 and have traveled as far north and as far west as possible in the continental US. About two years ago I noticed I was going through a set of back tires per year. I had hit a bump on the road and slightly bent the rear axle, which caused the back tires to camber out. Then, on my last big trip to Hershey, PA, I hit another loopy-doo on a northeastern Alabama highway and broke a leaf spring. Regardless of a desire to upgrade, my suspension needed attention.

I found that we did a really great thing by getting under the RV and doing a heavy inspection. There was more rust than I cared for on the springs. The bolts were worn. And the axles were a bare minimum when under a full load. We're upgrading the stock suspension with a Morryde Alltrek 4000 and wetbolt upgrade kit, Dexter D60 axles, and a galvanized five-leaf spring* rather than the four-leaf springs that came stock with this unit. Amsoil water-resistant grease is used in the Morryde Wetbolt Upgrade Kit to ensure a much longer life.

Overall, this project was much easier than I expected. We were careful to preplan our tools and techniques. Below is a list of items you will need to prepare, and Morryde provides great instructions for their parts. We found a good deal on the Dexter D60 6,000 lb axles with 6 x 5.5 12 in hubs at Dexter Parts Online, a great group of guys in western South Carolina.

Tool list:

  • Heavy Duty Jack Stands
  • Floor Jack (recommend 4 Ton)
  • Safety glasses
  • Gloves
  • Ball peen hammer
  • rubber mallet
  • metal punch (flat face)
  • Wrenches
  • 1/2” ratchet and sockets
  • 1/2” torque wrench
  • 1/2” impact wrench and impact sockets
  • Electrical Tools (diagonal cutters, crimpers, 10-12 gauge wire may be needed, zip ties, electrical tape, maybe some flextape 4” wide)
  • Connectors (silicone filled)

This was probably the BEST how-to video I have ever watched. We replaced our Lippert axles two years ago with Dexter but used a suspension shop to do it. Had I watched this video first, I certainly would have replaced the suspension springs and may have even done it myself. Great camera work and use of time. Thanks Robert!!!

Thanks for sharing that experience with us. Couple of questions, did you have to change the steps into the trailer or hitch setup with the additional trailer height? How did your backs hold out ha-ha? I like the idea of using dollys.
