Where you place stands depends on the job at hand... The rear axel is a good place in most cases, unless you are doing bushings. In that case the area where the jack goes is better. That way you can work the axel as needed..

The front jack points are good places to work the front suspention as if you wanted to deal with the struts...

If you raise the front end for a oil change you can place the stands under the lower control arm.

What is bothering me is no one said to leave the car in neutral and have NO brake set. Place blacks near a wheel fore and aft but not so the wheel can not roll at all! Raising car makes it roll towards a jack, and it must roll or the jack most roll if you raise any pair of wheels at once..

If not you are in danger of having the car slide off the jack, or tipping a jack over!

The jack that comes with the car is meant to change a flat and that is about all it is good for if that... if you were to use 2 jacks like that on the same side you would see the other side drag towards the jacks...

Raising 2 wheels on the same side is not standard...

A half decent floor jack cost about $125.00 and if you intend to work on a car for more or less any project a good jack is what you want. It is Safer and it works faster....

If you raise the front or the rear it matters not.. Once stands are in place under one end it does matter that the jack rolls towards the stand in place!

If the jack does not roll then you are pulling the car OFF the stands.. Stands will not slide.

It might be you think the jack cost is high, but it isn't compared to a trip to the morgue....... Mac
