Jacking up rear end while on ramps?

I have my car on ramps right now, front end elevated, but I need to raise up the rear to the same level so I can put in jack stands. My concern is the car rolling off the ramps once I jack up the rear, since the brakes aren't engaged in the front, obviously. Since both rear tires will be lifting off the ground simultaneously, there will be no braked wheels. But the other problem is, if the front wheels are braked, doesn't that mean the car won't "rotate" into a level position? Anyway, looking for advice on avoiding disaster!

Make sure the car is against the rear of the ramp that way the tire has room to rotate as you jack the rear up.

Done this dozens of times. I use the pumpkin of the rear for lifting (this is up to you, just telling you what I do, if you do, make sure it is forward of the rear diff cover.) as long as the wheels on your jack are free to move forward as you lift the rear, you will be fine and don't worry about having the front brakes on. once in the air, I use a spot just forward of the rear lower control arm mounts to place my jack stands. I have another set I use for the rear diff. as I said, I use the pumpkin for lifting the rear of my car, others may say not to and that's their opinion. good luck

As stated above use a floor jack under the pumpkin. My exception is to place the jack stands under the differential instead of the frame. Its a lower point for the stands to reach easier.

And that keeps the axle higher off the ground, allowing more room underneath with the rear springs carrying the car weight.

Most ramps have an up-turned "bump" up front, to tell the driver when the tire is all the way on the flat pad. On my ramps that pad is about 2" high, not much, but unless the rear were raised REAL high, the will not roll off the front of the ramp.

I have lifted by the pumpkin for more years than imaginable with no mishap. Ford as well as others recommend against it because it places high stress on the axle tubes where they enter the pumpkin. In the case of a weak puddle weld there breakage of the weld is possible. If you break one, it will leak fluid there.

Awesome advice guys, thanks. And yes, I've lifted several cars by the rear diff (not just Mustangs) with no problems. It's the best way I've found to avoid damage to the bodywork by jacking at a place other than the jack points. My problem is always finding a point where you can jack up, but still place the jack stands in the proper place. Obviously, you can't jack up at the jack point and also place the stand there. The rear diff trick is a great solution!

When I need all 4 corners in the air, I jack up the fronts and place the ramps under each wheel backwards. The ramps have a built-in stop. Place the stop right at the back edge of the tire. In reverse they prevent the vehicle from rolling back when jacking up the rear.
