Jacking up with MorRyde IS

I'm going to pull the tires off one by one to have TPMS installed. We are camping, so I'm not breaking down camp to drive to the tire dealer.

I'd prefer to lift each tire rather than lift the trailer frame, but not understanding the instructions in the service manual Located here Instructions are on page 4, and trying to understand It is permissible to jack up a unit equipped with a MORryde Independent Rubber Suspension System only on the Beam Assembly under the Rubber Springs" That appears to be on an angle, so how would I use a bottle jack to raise the wheel?

Trying to raise the wheel as opposed to lifting the whole frame up on one side.

  • Good advice above. I would use a EZ Jack type to lift. Or lift the frame using the trailer mfg instructions. A bottle jack could slip, one with a saddle might be better. The typical tire dealer might be clueless about how to jack a MORryde suspension and just use a scissor jack.

    Regardless connect the tow vehicle for fore-aft stability and raise any stabilizing jacks

    Why not wait until you break camp and have it done? Or install TMPS sensors on the tire stems? Pros and cons to internal vs external sensors.
  • I agree that using a ramp is the safe way...also the easy way.
  • If you have the hydraulic rams simply lift it off the ground. ORRRR buy this if it makes you feel better. TrailerAid Plus.

    I would not lift on the IS suspension!!!

  • Does your RV have jacks? If so can't you lift it off the ground and put jack stands or blocks under it as a measure in case the jacks fail?

    And what kind of TPMS? Most aftermarket ones just screw on to the shrader valve. Sounds like you have ones that need installed to the inside of the rim.
