Getting new Goodyear G614's very soon. Over the years I've had installers tell me different "musts" for safe jacking techniques and jack placement positions. Last time on this large very heavy Grand Junction they used 2 floor jacks (doing one side of the trailer at a time) one jack under each of the axle to spring U bolts points, jacking both wheels "simultaneously' off the ground.
Others have said only jack under the frame, one jack in front of wheels and one behind. But on this trailer I have a propane gas pipe directly covering the underside of the front frame, that would be crushed.
On my lighter trailers, flat bed & horse, the jacking points are not quite as critical because the trailer lifts more easily. But on this heavy trailer damage can be done jacking improperly. Can anyone tell me the right way to lift one side at a time on a large heavy 5ver????
If you have the hydraulic Level-Up system use it. All 4 at once.
