where should I put my jack stands?

[Creager]

Creager, that's kind of what I thought you meant, I had just never heard the term before, that's all.

The weight does transfer from side to side, but it does so through the spring perches on the axle tubes, which transmit the force through the bearings to the axle shaft. Very little of the force due to the weight of the vehicle is borne by the carrier bearings and transmitted to the diff housing. The lateral forces are, but they don't act to bend the axle.

-Joe.

I made that term up hahah

I would figure that my theory would/might in fact bend an axle before jacking on it would. Simply because the force from the weight of the truck plus the kinetic force of the truck is more then the weight of the truck itself... I don’t know I just think of the stuff I don’t actually know ... you are probably much more educated then I. I just build 'em

 

[gijoecam]

You are correct in that the forces will be higher than the static forces, but the way the load will be transferred, it will be bourne primarily by the chassis through the spring. The forces seen at the diff housing are far, far lower than when you try and lift the back end up by the housing.

Bounce the diff off a rock, however.....

thanks guys we put the jack stands on the metal peice between the wheels that is the pic with the bar lowest to the groun with the big mud clump on it

That's the front cross-member. For lifting the front end with a single jack, that's the easiest way, for sure. I'm really not sure that there's a "better" way without using a hoist. (Yet another reason I need one LOL!!)

Nah... I still like using the torsion bars... Hah.

 

[spindlecone]

so nobody understands that your truck shifts weight from side to side over humps, bumps and dips... interesting. I figured anyone with a high-school diploma would find that self-explanatory.

spindlecone, i am glad you know how to put blocks on your jack... mines got a nice rubber cusion hehe

Prior to your edit you said: And spindle, most jacks nowadays have a cusion.
Well mine is old, in the morn I shall slay some geese and command the old Squawe to make a kevlar, down stuffed cushion
Than I can ******* anywhere I want

 

[Crispy Niggets]

ok guys, thanks for all your imput, Im been done for a while, so I hope this thread helps someone else, hopefully not confusing the sh** out of them like it did to me, lol NOW YOU GUYS RESPOND AFTER I HAD COMPLETED THE INSTALL A DAY AFTER THE POST!

No, I understood what you meant, it's just that your theory is flawed. The flaws have been stated else where in this thread, so I won't go into it.

Hey, if it broke, I'd take full responsibility. If these bars can't support the weight of the vehicle, I'm sure that they'd be snapping like twigs everytime you bottom them out on a rock while off roading... same goes for the differential pumpkin as far as I am concerned.

Dunno if this was mentioned but these bars support the weight of the vehicle torsionally, not latteraly shear.

It more or less has been, and that's been my argument from the start..... by resting it on the torsion bar itself, you're placing the bar in bending and shear, loads for which the 'torsion' bar was not designed.

I figured I'd jump in with my 2 cents. When I first got the truck I jacked it up in the front by a metal beam that ran across and under the engine bay. Not sure what that part is called but it did cause it to bend a little. Since then I have been jacking up on the control arms in the front. It's a little tricky to get a 2-ton jack cup and the jack stand in there but it seems to work much better.

In the back I jack and stand by the axle. I read in my Haynes manual that if you jack on the diff it could cause leaks. I did not want leaks so I opted to jack on the tube one side after the other.

Am I doing things correctly now?

 

[IZwack]

Sounds about right. You can still jack it up via that metal cross member that runs under the engine bay (that houses the rack and pinion) - just use a piece of 2x4 lumber (or something similar) between the jack and the cross member so the cup doesnt dig in and bend the metal.

 

[jayhawkexplorer]

Wow. Its threads like this that make me fear for the human race. There are factory jacking points front and rear. None of these points is hard to locate, and are probably easier then using something as stupid as the torsion bars. What is so tough for you guys to figure out about doing things right? This entire thread is kind of like beating my head against a cinder block for hours. I'd probably break it eventually, but I could get hurt a lot in the process. Kind of like jacking by the torsion bars.

 

[spindlecone]

Agree with you Jay 100%
We have 52 posts, on the subject of how to jack up a truck, thats lunacy

 

[IZwack]

but I think its better that we have 52 or 104 posts on this one thread than have some future board member jack up his/her vehicle somewhere where it shouldnt be jacked up.

And we learned a valuable lesson: Don't have your truck serviced anywhere near Ajax, Ontario!

The list go's on

Actually, I work an hours drive from Ajax, Ontario... but hey, your loss... certainly not mine...

But the problem still is that after all these posts, we still have a bunch of ignorant people (including two who claim to be Ford FACTORY SERVICE TECHS) that don't jack vehicles in the correct manner. That's scary. And stupid.

Is a book that comes with all autos, called the owners quide, is normally located in the glove box.
That being said, if one can read, one can figure out the complexitys of how to jack up your truck
