Its a pain. You first have to drop the torsion bars under the truck. Then get a pulley puller and push the torsion bars back up to remove the metal pieces holding the torsion bars in. Remove the puller and take the torsion bars off. You will then need to remove the bracket holding the torsion bars. ONce that is done, you will have enough clearance to drop the tranny. The hard part is getting the torsion bars back on. Come to think of it, I think you can buy a tool from Ford to pull the torsion bars off. It pretty expensive that why I use a pully puller. Not all F-150s have torsion bars. Buy a Chilton Repair Manual for your correct year. It'll tell you everything step by step.
You need to crank them up.
In the tread there are small 'bars' at the bottom surface about 2-3 mm high, when average tread wear is down to these 'bars' you should get new tires.
no it does not.
first you will need to have a crown vick in order to do this,
Yes you do have to remove the bars or at least the torsion bar cross member and to do that you either need the otc tool or use a two jaw puller make sure to measure the bolt height before you start and set it the same they control your ride height
If it 4x4 you need to crank the torsion bars so no rubbing happens but you can easily put 285/70R17
You really need the Bentley Manual as this could be really DANGEROUS. The only way to raise or lower it is to take apart the suspension. The spring plates that connect to the Torsion bars are under several hundred pounds of pressure. They have "torsion bars" that you can rotate to raise or lower it. The "torsion bars" have splined ends, one end is fine (eg40) and the other is coarse (eg20). You rotate the bars one way and the cover the other way to raise it a lot or a little. Do a search on the internet as there are places that walk you through it also. Be aware as you may have to have the rear end realigned.
What about it? What do you need to know?
You need a torsion key.. most mechanics can twist the bar for cheap
We need more info. Need to know the symptoms. Need to know what it does and does not do.
I need to calculate the stress resulting from a torsion moment on a hollow steel section as well as a flat plate.
