Tentum, I'd listen to Dave Willis... I mean no disrespect to the other forum members... but... I have been reading the forum for a while now... I have read what Lippert supposedly states, "jack up from the frame only or the world will end" Now I want you to visit the world of what if... what if you rode over a an obstacle, wouldn't one tire raise more than the one next to it ? What if, instead, you raised it the same amount with a jack... Shush, what if you changed tires now ??? Opps, so much for the God of NO "NO.... ya can't or shouldn't". I am going to jack my RV up by the axle just to see what happens... know what I think ? NOTHING will happen... again, I think Dave Willis and the guys in the shop been there done that.... JMO Tom I see no reason giving physics and stress why you can't just jack up one axle to change a tire... If Lippert or anyone else can give me an engineered explanation with stress loads and arm weight dynamics, then I see no reason WHY we can't raise our RV's using the axle JMO Tom
PS. Hey Lippert, ya up to my challenge ?
