Im gonna be replacing the rear lower control arms. Do i have to jack up the rear to replace them or can i drive it up my ramps?

I have a set of ramps or planks i made at work. I drive up them (12.5" wide and 15 feet long )and it keeps all 4 tires on them and it lifts the car about 10" up or so. They work awesome for oil changes and exhuast work.

 

The LCA's are the only things that stabilize the rear axle assembly, preventing front-to-back movement. Support the chassis with jack stands under the rear subframes. Support the axle assembly with a floor jack.

 

Good to know, thank you sir
