where do you put your jack

I posted the question a couple of days ago about what jack is best in lifting a 5er. Now, a bigger question is, where do you put the jack and the lift point. I've read several debates on this on the internet in general. Some say lift by the frame only, some say you could twist or bend the frame and never do that. You should lift using the spring u-bolts. On my 5er, there's not much room, you would have to lift way in front of the tire or way in back of the flat tire if you used the frame. Lift on the axle? Spring hangers or u bolts? Where would you lift? I think my book states to lift by the frame, but to do that I would have to put the jack way in front or back of the flat tire which means you would have to jack higher to get the tire off the ground which means a greater chance of twisting the frame.

  • 07.5 Mobile Suites weighing over 18K in pic. Safest easiest way to do maintenance and road side repairs. Also light weight!

  • Bottle jack on the spring perches. I axle flipped my trailer so the springs are on top but the bottom perch still works fine.
  • Bottle jack. Under bottom spring leaf. Only lifts the wheel without lifting the spring flex distance. Safer under flat spring leaf than U bolt or axle between U bolts.
  • If you are not needing to take off all the wheels on one side, don't forget the advantages of leveling blocks/ wood blocks under the tire you do not plan to remove. Greatly minimizes the amount of jacking required.
  • I have had to change a couple tires by the side of the road, compliments of Carlisle China ST tires. :) I put my 10 ton bottle jack under the axle U-bolts, but not on the axle tubing itself.

    Trying to jack the frame high enough to allow a person to remove the tire would require extensive frame support and a very high lift jack. And I wouldn't do it anyway for fear of putting excessive stress on a single point of the frame.

    And yes, my manual says to never use a jack on the axle. IMO another CYA statement insisted upon by the lawyers.
  • I have 6-point levelers and will extend out one side, lift the tires, place the jackstands under the axle at the spring plate, and repeat for the other side.
  • Jacking should always be under the spring hanger. In other words directly under the spring. If for some reason your working on the axles, then by all means you need to jack the frame to get the axles hanging free.
