Jacking the Pumpkin

[Kilgore Trout]

From the master who created www.bullittarchive.com:
--------------------------------------------
The rear axle is not perfectly straight. To allow the rear end to track correctly, there is about a 1 degree negative camber built into the rear axle. Basically what that means is that instead of axle being parallel with the ground, the differential is a little lower than the center line and the the top of the wheels tilt slightly towards the vehicle.

If you lift the vehicle from the differential, you are putting stress on both left and right axle housings where they meet the differential, at the same time. They were not designed to perform in this manner. Although you may not break anything, you do not want to stress this area or slightly tweak it and remove or reduce this 1 degree negative camber.
--------------------------------------------

But my buddy who is a skilled mechanic says BS to this! What is the answer? It is soooo much easier to just jack the pumpkin...

Look in your owner's manual. For my 2001 Mustang GT it is on page 141 but, just look up jacking or tire changing. They spell it out in bold "Never use the rear differential as a jacking point"

Yeah yeah, I know Ford says not to do it, bullittarchive says not to do it... I guess I won't do it

ever again...

I jack under the car near the torque boxes just in front of where the rear lower control arms connect. That's where the Chilton's manual says to do it.

I jack my 8.8 pumpkin all the time and I never had a problem I am not telling anybody else to do it I'm just not scared of it breaking If any one has experienced a problem from jacking the pumpkin chime in and maybe I'll stop .
