Why then does the owner's manual mention that the stock jack should be placed under the axle when changing tires? Could it be that it is OK to use the axle as a lift point for a short time? I find that my 2 1/2 ton hydraulic jack does not go high enough to lift the tire off the ground when I jack under the frame. I would like to jack under the axle; put a jackstand under the frame, remove the wheel and then remove the jack from under the axle so the jeep rests on the jackstand under the frame. Can this potentially damage the axle? |

Letting the axle hang on a frame stand (axle stand under the frame) is how folks change springs and shocks. Jacking at the end of the tube means the axle stands have to be inboard of that or it would mean you jack on the center diff and set the stands outboard which will wreck the poor things.
