people say that relying on just jack stands is not safe..i'm guessing 2 jack stands for lifted 2 wheels.(2~3 tons each) If i use 1 jack underneath the frame and another one behind the wheel, would it be safer than using a ramp?

 

When it comes to safety especially a car falling on you one cant be too safe considering most of the time if something happens most of the time no one is around. It really depends what the equipment is rated at. I've seen many ppl fully supend a car in the air with 4 jack stands on each corner.

 

i always use jackstand + jack and a cement block placed nearby there incase one or both give.
never know when a jackass friend might stop by and try to attempt something funny to scare you and it goes wrong.
watched too much final destination crap i guess.

 

^^^^ I do the same. I sure don't want a 3500 pound car on top of me. So far so good, I've change my whole diff pumpkin this way.

 

i agree....F that... lady dialed 911 said her husband was hit by a car..we got there..i had to use the jaws/spreaders to lift the car off of him...bleeding out his ears cuz his control arm almost popped his head like a zit
